Thylacine

Reproduction

There is evidence for at least some year-round breeding (cull records show joeys discovered in the pouch at all times of the year), although the peak breeding season was in winter and spring.^[45] They would produce up to four joeys per litter (typically two or three), carrying the young in a pouch for up to three months and protecting them until they were at least half adult size. Early pouch young were hairless and blind, but they had their eyes open and were fully furred by the time they left the pouch.^[68] The young also had their own pouches that were not visible until they were 9.5 weeks old.^[45] After leaving the pouch, and until they were developed enough to assist, the juveniles would remain in the lair while their mother hunted.^[69] Thylacines only once bred successfully in captivity, in Melbourne Zoo in 1899.^[70] Their life expectancy in the wild is estimated to have been 5 to 7 years, although captive specimens survived up to 9 years.^[48]

In 2018, Newton et al. collected and CT-scanned all known preserved thylacine pouch young specimens to digitally reconstruct their development throughout their entire window of growth in their mother's pouch. This study revealed new information on the biology of the thylacine, including the growth of its limbs and when it developed its 'dog-like' appearance. It was found that two of the thylacine young in the Tasmanian Museum and Art Gallery (TMAG) were misidentified and of another species, reducing the number of known pouch young specimens to 11 worldwide.^[68] One of four specimens kept at Museum Victoria has been serially sectioned, allowing an in-depth investigation of its internal tissues and providing some insights into thylacine pouch young development, biology, immunology and ecology.^[71]

Feeding and diet

The thylacine was an apex predator,^{[4][page needed]} though exactly how large its prey animals could be is disputed. It was a nocturnal and crepuscular hunter, spending the daylight hours in small caves or hollow tree trunks in a nest of twigs, bark, or fern fronds. It tended to retreat to the hills and forest for shelter during the day and hunted in the open heath at night. Early observers noted that the animal was typically shy and secretive, with awareness of the presence of humans and generally avoiding contact, although it occasionally showed inquisitive traits.^[72] At the time, much stigma existed in regard to its "fierce" nature; this is likely to be due to its perceived threat to agriculture.^[73]

Historical accounts suggest that in the wild, the thylacine preyed on small mammals and birds, with waterbirds being the most commonly recorded bird prey, with historical accounts of thylacines predating on black ducks and teals with coots, Tasmanian nativehens, swamphens, herons (Ardea) and black swans also being likely items of prey. The thylacine may also have preyed upon the now extinct Tasmanian emu.^[74] The most commonly recorded mammalian prey was the red-necked wallaby, with other recorded prey including the Tasmanian pademelon and the short-beaked echidna. Other probable native mammalian prey includes other marsupials like bandicoots and brushtail possums, as well as native rodents like water rats.^[75] Following their introduction to Tasmania, European rabbits rapidly multiplied and became abundant across the island, with a number of accounts reporting the predation of rabbits by thylacines.^[76] Some accounts also suggest that the thylacine may have preyed on lizards, frogs and fish.^[77]

European settlers believed the thylacine to prey regularly upon farmers' sheep and poultry.^[a] However, analysis by Robert Paddle suggests that there is little evidence that thylacines were significant predators of sheep or poultry (though some accounts suggest that they may have attacked them on occasion), with many sheep deaths likely caused by feral dog attacks instead.^[79] Throughout the 20th century, the thylacine was often characterised as primarily a blood drinker; according to Robert Paddle, the story's popularity seems to have originated from a single second-hand account heard by Geoffrey Smith (1881–1916)^[80][81] in a shepherd's hut.^[82]

Recent studies suggest that the thylacine was probably not suited for hunting large prey. A 2007 study argued that, while it could open its jaws wide like modern mammalian predators that consume large prey, the canine of the thylacine was not suited for slashing bites like that of large canids, indicating, based on the assumption that the bite was largely derived by its skull, that it hunted small to medium-sized prey as a solitary hunter.^[83] A 2011 study by the University of New South Wales using advanced computer modelling indicated that the thylacine had surprisingly feeble jaws; animals usually take prey close to their own body size, but an adult thylacine of around 30 kg (66 lb) was found to be incapable of handling prey much larger than 5 kg (11 lb), suggesting that the thylacine only ate smaller animals such as bandicoots, pademelons and possums, and that it may have directly competed with the Tasmanian devil and the tiger quoll.^[84][85] The dental microwear of the thylacine, though containing larger pits and more of them, overlapped significantly wth that of the Tasmanian devil.^[86] Another study in 2020 produced similar results, after estimating the average body mass of thylacine as about 16.7 kg (37 lb) rather than 30 kg (66 lb), suggesting that the animal did indeed hunt much smaller prey, although it was capable of taking down larger prey when necessary.^[39] The cranial and facial morphology also indicate that the thylacine would have hunted prey less than 45% of its own body mass, consistent with modern carnivores weighing under 21 kg (46 lb) which is about the average size of a thylacine.^[87][39]

A 2005 study showed that the thylacine had a high bite force quotient of 166, which was similar to that of most quolls, indicating that it may have been able to hunt larger prey relative to its body size.^[88] A 2007 study also suggested that it would have had a much stronger bite force than a dingo of similar size, though this particular study argued that the thylacine would have hunted smaller prey.^[83] A biomechanical analysis of the 3D skull model suggested that the thylacine would have likely consumed smaller prey, with its skull displaying high levels of stress that are not suited to withstand forces, and with its bite forces being estimated at a smaller value than that of Tasmanian devils.^[84] A 2014 study compared the skull of a thylacine with that of modern dasyurids and an earlier thylacinid taxon Nimbacinus based on biomechanical analysis of their 3D skull models; the authors suggested that while Nimbacinus was suited to hunt large prey with a maximum muscle force of 651 N (146 lb_f) which are similar to that of large Tasmanian devils, the thylacine skull displayed a much higher stress in all areas compared to its relatives due to its longer snout.^[85] If the thylacine was indeed specialised for small prey, this specialisation likely made it susceptible to small disturbances to the ecosystem.^[84]

It has been suggested on the basis of the canine teeth and limb bones that the thylacine was a solitary pounce-pursuit predator that hunted smaller prey with trophic niches similar to relatively smaller canids like the coyote, and that it was not as specialised as large canids, hyaenids and felids of today: its canine lacked the adaptation for producing slashing or deep penetrating bites, and its anatomy was not suited for running fast in high speed.^[26][89] However, the trappers reported it as an ambush predator hunting alone or in pairs mainly at night.^[45][90] The elbow joint morphology and the forelimb anatomy of the thylacine also suggest that the animal was most likely an ambush predator.^[91][92]

The stomach of a thylacine was very muscular, capable of distending to allow the animal to eat large amounts of food at one time, probably an adaptation to compensate for long periods when hunting was unsuccessful and food scarce.^[45] In captivity, thylacines were fed a wide variety of foods, including dead rabbits and wallabies as well as beef, mutton, horse and, occasionally, poultry.^[93] There is a report of a captive thylacine that refused to eat dead wallaby flesh or to kill and eat a live wallaby offered to it, but "ultimately it was persuaded to eat by having the smell of blood from a freshly killed wallaby put before its nose."^[94]

Extinction on the Australian mainland

Australia lost more than 90% of its megafauna around 50–40,000 years ago as part of the Quaternary extinction event, with the notable exceptions of several kangaroo and wombat species, emus, cassowaries, large goannas, and the thylacine. The extinctions included the even larger carnivore Thylacoleo carnifex (sometimes called the marsupial lion) which was only distantly related to the thylacine.^[95] A 2010 paper examining this issue showed that humans were likely to be one of the major factors in the extinction of many species in Australia although the authors of the research warned that one-factor explanations might be over-simplistic.^[95] The youngest radiocarbon dates of the thylacine in mainland Australia are around 3,500 years old, with an estimated extinction date around 3,200 years ago, synchronous with that of Tasmanian devil, and closely co-inciding with the earliest records of the dingo, as well as an intensification of human activity.^[96] Recent studies have documented additional thylacine depictions in Arnhem Land, including examples in rock art styles that may date to within the last 1,000 years, raising questions about whether the species may have persisted locally later than previously assumed, although this remains uncertain.^[97]

A study proposes that the dingo may have led to the extinction of the thylacine in mainland Australia because the dingo outcompeted the thylacine in preying on the Tasmanian nativehen. The dingo is also more likely to hunt in packs than the more solitary thylacine.^[98] Examinations of dingo and thylacine skulls show that although the dingo had a weaker bite, its skull could resist greater stresses, allowing it to pull down larger prey than the thylacine. Because it was a hypercarnivore, the thylacine was less versatile in its diet than the omnivorous dingo.^[99][83] Their ranges appear to have overlapped because thylacine subfossil remains have been discovered near those of dingoes. Aside from wild dingoes, the adoption of the dingo as a hunting companion by the indigenous peoples would have put the thylacine under increased pressure.^[98]

A 2013 study suggested that, while dingoes were a contributing factor to the thylacine's demise on the mainland, larger factors were the intense human population growth, technological advances, and the abrupt change in the climate during the period.^[100][101] A report published in the Journal of Biogeography detailed an investigation into the mitochondrial DNA and radio-carbon dating of thylacine bones. It concluded that the thylacine died out on mainland Australia in a relatively short time span.^[102] A study published in 2025 proposed that gene losses which accumulated throughout the thylacine's evolutionary history made the species more susceptible to extinction. The authors of the study suggest that genetic traits which would have made the thylacine more capable of adapting to environmental changes were lost and that these losses may have contributed to their eventual demise.^[103]

Ken Mulvaney has suggested, based on the high number of rock carvings of the thylacine on the Burrup Peninsula, Aboriginal Australians were aware of, and concerned about the thylacine's dwindling numbers around that time.^[104][105]

Decline and extinction in Tasmania

Although the thylacine had died out on mainland Australia, it survived into the 1930s on the island of Tasmania. The number of thylacines living at any given time prior to the arrival of Europeans is unclear, with a rough estimate of 2,000-4,000 or less given by Eric Guiler & Philippe Godard,^[64][106] and a higher estimate of 5,000 given by David Owen.^[107] They were rarely sighted, but slowly began to be credited with numerous attacks on sheep. This led to the establishment of bounty schemes in an attempt to control their numbers. The Van Diemen's Land Company introduced bounties on the thylacine as early as 1830, and between 1888 and 1909, the Tasmanian government paid £1 per head for dead adult thylacines and ten shillings for pups. In all, they paid out more than 2,200 bounties,^[64] but it is thought that many more thylacines were killed than were claimed for. Its extinction is popularly attributed to this hunting by farmers and bounty hunters.^{[48][108][109]}

In addition to persecution, it is likely that multiple factors rapidly compounded its decline and eventual extinction, including competition with wild dogs introduced by European settlers,^[110] erosion of habitat, already-low genetic diversity, the concurrent extinction or decline of prey species, and a distemper-like disease that affected many captive specimens at the time.^{[46][64][111]} A study from 2012 suggested that the disease was likely introduced into the wild thylacine population by humans around 1896. The marsupi-carnivore disease, as it became known, dramatically reduced the lifespan of the animal and greatly increased pup mortality,^[112] and spread across the island's thylacine population in an east-to-west pattern. Contemporary reports from the 1930s credit disease as the greatest threat to the species, although some later researchers have questioned its impacts in comparison to hunting.^[64] Work in 2012 indicated that the last of the thylacines in Tasmania had limited genetic diversity due to their complete geographic isolation from mainland Australia.^[113] Further investigations in 2017 showed evidence that this decline in genetic diversity started long before the arrival of humans in Australia, possibly starting as early as 70–120 thousand years ago.^[41] By the beginning of the 20th century, the increasing rarity of thylacines also led to increased demand for captive specimens by zoos around the world, placing yet more pressure on an already small, bottlenecked population.^[114] Despite the export of breeding pairs, attempts at rearing thylacines in captivity during the 20th century were unsuccessful, and the last thylacine outside Tasmania died at the London Zoo in 1931.^[115]

A 1921 photo by Henry Burrell of a thylacine holding a chicken in its mouth was widely distributed and may have helped secure the animal's reputation as a poultry thief. The image had been cropped to hide the fact that the animal was in captivity, and analysis by one researcher has concluded that this thylacine was a dead specimen, posed for the camera. The photograph may even have involved photo manipulation.^[116][117]

Thylacines apparently experienced population crash after 1905, with the total population estimated to be less than 700-800 individuals by the end of the government's bounty campaign in 1909.^[64][118] The species continued to decline, had become vanishingly rare by the 1920s. Despite the fact that the thylacine was believed by many to be responsible for attacks on sheep, in 1928 the Tasmanian Advisory Committee for Native Fauna recommended a reserve similar to the Savage River National Park to protect any remaining thylacines, with potential sites of suitable habitat including the Arthur-Pieman area of western Tasmania.^[119] By the 1930s, only four small subpopulations of thylacines in western Tasmania definitively survived, with the largest number of sightings in the Arthur-Pieman area.^[64]

The last known thylacine to be killed in the wild was shot in 1930 by Wilf Batty, a farmer from Mawbanna in the state's northwest. The animal, believed to have been a male, had been seen around Batty's house for several weeks or months.^{[120][121][27]} The last definitive record of a wild thylacine was a young male individual captured in late 1931 by James Millar Kaine and sold to exotic animal dealer James "tiger" Harrison, who sold several other thylacines to various buyers during his career.^[27][122] The animal was caught alive, but had a broken leg and had been beaten with a farm hoe. It was treated for its injuries by a local doctor, after which it was returned to Harrison.^[122] Later captures of thylacines in 1933 or 1936 are sometimes suggested, but these may be misreported.^[27]

Although there had been a conservation movement pressing for the thylacine's protection since 1901, driven in part by the increasing difficulty in obtaining specimens for overseas collections, political difficulties prevented any form of protection coming into force until 1936. Official protection of the species by the Tasmanian government was introduced on 10 July 1936, 59 days before the last known specimen died in captivity.^[123] The thylacine held the status of endangered species until the 1980s, because international standards at the time stated that an animal should not be declared extinct until 50 years had passed without a confirmed record. Since no definitive proof of the thylacine's existence in the wild had been obtained for more than 50 years, it met that official criterion and was declared extinct by the International Union for Conservation of Nature in 1982^[2] and by the Tasmanian government in 1986. The species was removed from Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) in 2013.^[124]

Last known individual

The last captive thylacine lived as an endling (the known last of its species) at Hobart Zoo (alternatively Beaumaris Zoo) until its death on the evening or night of 7 September 1936.^[27][125] The circumstances of the endling's capture, its life history, death and sex are debated, and conflicting information has been reported. It is occasionally claimed that the last animal was the offspring of a female housed at the zoo during the 1920s, despite it having a distinctive scar on its leg from a snare trap that implies wild capture, and the zoo not having thylacines for a period between 1929 and 1930. The date of the endling's apparent capture (and historically its date of death as well) is sometimes reported to have been 1933 or 1934, but there are no surviving records of any live thylacines being sold after 1931.^[27] Author Stephen Sleightholme and coauthors proposed that the thylacine caught by James Kaine in 1931 may have been sold to the Hobart Zoo,^[122] but in a later work Sleightholme and another author considered this incorrect and suggested the last wild capture was ultimately sold by James Harrison to a buyer that was not a zoo or museum.^[27]

According to authors Gareth Linnard and Sleightholme, the endling was a male accidentally snared as a juvenile in 1930 near Mount Bischoff, and temporarily kept by the local Delphin family as a paid attraction along with an injured juvenile female. The Hobart Zoo purchased the juvenile male thylacine from the family in late 1930 after the female, which may have been its sibling, had already died. This male had a distinctive snare scar around its leg which it carried throughout its life, and which is visible in all photos and videos of the zoo's thylacine during the 1930s. It deteriorated in health throughout 1936, and according to Linnard and Sleightholme died of age-related complications in September of that year after being housed at the zoo for nearly six years. After death its body was apparently lost, possibly having been sent to museum director Colin Mackenzie, who collected thylacine remains.^[27]

According to authors Robert Paddle and Kathryn Medlock, the male captured by the Delphin family actually died in May 1936 and was replaced shortly afterwards. These authors propose the endling was instead an elderly female captured by Elias Churchill with a snare trap that was sold to the zoo in May 1936.^[126] This sale was not publicly announced because the use of traps was, according to these authors, illegal, and Churchill could have been fined.^[125] After its death, the remains of the female endling were transferred to the Tasmanian Museum and Art Gallery, where they were not properly recorded by the museum because the animal had been caught illegally. The remains would then lay undiscovered for decades until a taxidermist record dated from 1936 or 1937 mentioning the animal was noticed in 2022.^[127] Linnard and Sleightholme have criticized this account, as May 1936 predated the species being protected and thus there would be no need for secrecy, Churchill only recounted a single, separate instance of catching a thylacine alive during the 1920s, and a report from 1937 notes no reliable wild thylacine sightings for years.^[27]

An earlier work by Paddle claims the animal is believed to have died as the result of neglect—locked out of its sheltered sleeping quarters, it was exposed to a rare occurrence of extreme Tasmanian weather: extreme heat during the day and freezing temperatures at night.^[128] This account of the animal's death has been widely publicized since, but has subsequently been questioned in favour of the animal dying of old age. The sleeping quarters of the thylacine exhibit were apparently readily openable from outside, and it was considered a valuable star attraction by the zoo. Visitors near the end of the animal's life also described it as mangy, limping, and old, which is consistent with its appearance in the two last known photographs of the animal from 1936. This implies the animal was near the end of its species' naturally short lifespan.^[27]

In May 1968, an individual named Frank Darby, claiming to be a curator at the Hobart Zoo, invented the myth that the endling was called Benjamin. Darby discussed the matter with the Victorian naturalist Graham Pizzey, and the account entered the Melbourne press and exploded in popularity. Despite being regularly debunked over the years due to Darby never working at the zoo and clearly being unfamiliar with the species, the myth continues to circulate even in modern-day media, with Wikipedia itself repeating the invention.^[129]

A 45 second black-and-white motion picture showing the Hobart Zoo's presumed last thylacine in its enclosure was taken in 1933, by naturalist David Fleay.^[130] In the film footage, the thylacine is seen seated, walking around the perimeter of its enclosure, yawning, sniffing the air, scratching itself, and lying down. Fleay was bitten on the buttock whilst shooting the film.^[130] In 2021, a digitally colourised 80-second clip of Fleay's footage of the thylacine was released by the National Film and Sound Archive of Australia, to mark National Threatened Species Day. The digital colourisation process was based on historic primary and secondary descriptions to ensure an accurate colour match.^[131][132] The last known footage of this individual, and of the species, was filmed in 1935 by Sidney Cook for the promotional film Tasmania the Wonderland.^[133]

Searches and unconfirmed sightings

Between 1967 and 1973, zoologist Jeremy Griffith and dairy farmer James Malley conducted what is regarded as the most intensive search for thylacines ever carried out, including exhaustive surveys along Tasmania's west coast, installation of automatic camera stations, prompt investigations of claimed sightings, and in 1972 the creation of the Thylacine Expeditionary Research Team with Dr. Bob Brown, which concluded without finding any evidence of the thylacine's existence.^[134]

The Department of Conservation and Land Management recorded 203 reports of sightings of the thylacine in Western Australia from 1936 to 1998.^[72] On the mainland, sightings are most frequently reported in southern Victoria.^[135]

According to the Department of Primary Industries, Parks, Water and Environment, there have been eight unconfirmed thylacine sighting reports between 2016 and 2019, with the latest unconfirmed visual sighting on 25 February 2018.^[136]

Since the disappearance and effective extinction of the thylacine, speculation and searches for a living specimen have become a topic of interest to some members of the cryptozoology subculture.^[137] The search for the animal has been the subject of books and articles, with many reported sightings that are largely regarded as dubious.^[138]

A 2023 study published by Brook et al. compiles many of the alleged sightings of thylacines in Tasmania throughout the 20th century and claims that, contrary to beliefs that the thylacine went extinct in the 1930s, the Tasmanian thylacine may have actually lasted throughout the 20th century, with a window of extinction between the 1980s and the present day and the likely extinction date being between the late 1990s and early 2000s.^[65][139]

In 1983, the American media mogul Ted Turner offered a $100,000 reward for proof of the continued existence of the thylacine.^[140][141] In March 2005, Australian news magazine The Bulletin, as part of its 125th anniversary celebrations, offered a $1.25 million reward for the safe capture of a live thylacine. When the offer closed at the end of June 2005, no one had produced any evidence of the animal's existence. An offer of $1.75 million has subsequently been offered by a Tasmanian tour operator, Stewart Malcolm.^[142]

Possible revival

The Australian Museum in Sydney began a cloning project in 1999.^[145] The goal was to use genetic material from specimens taken and preserved in the early 20th century to clone new individuals and restore the species from extinction. Several molecular biologists dismissed the project as a public relations stunt.^[146] In late 2002, the researchers had some success as they were able to extract replicable DNA from the specimens.^[147] On 15 February 2005, the museum announced that it was stopping the project.^[148][149] In May 2005, the project was restarted by a group of interested universities and a research institute.^[142][150]

In August 2022, it was announced that the University of Melbourne would partner with Texas-based biotechnology company Colossal Biosciences to attempt to re-create the thylacine using its closest living relative, the fat-tailed dunnart, and return it to Tasmania.^[151] The university had recently sequenced the genome of a juvenile thylacine specimen and was establishing a thylacine genetic restoration laboratory.^{[152][153][154][155][156]} The research from the University of Melbourne was led by Andrew Pask.^[157] The project was regarded with scepticism by other, uninvolved scientists.^[157]

DNA sequencing

A draft whole genome sequencing of the thylacine was produced by Feigin et al. (2017) using the DNA extracted from an ethanol-preserved pouch of a young specimen provided by Museums Victoria. The neonatal development of the thylacine was also reconstructed from preserved pouch young specimens from several museum collections.^[68] Researchers used the genome to study aspects of the thylacine's evolution and natural history, including the genetic basis of its convergence with canids, clarifying its evolutionary relationships with other marsupials and examining changes in its population size over time.^[158]

The genomic basis of the convergent evolution between the thylacine and grey wolf was further investigated in 2019,^[159] with researchers identifying many non-coding genomic regions displaying accelerated rates of evolution, a test for genetic regions evolving under positive selection. In 2021,^[160] researchers further identified a link between the convergent skull shapes of the thylacine and wolf,^[158] and the previously identified genetic candidates.^[159] It was reported that specific groups of skull bones, which develop from a common population of stem cells called neural crest cells, showed strong similarity between the thylacine and wolf^[160] and corresponded with the underlying convergent genetic candidates which influence these cells during development.^[159] In 2023, RNA was extracted from a 130-year-old thylacine specimen in Sweden; this represented the first time RNA has been extracted from an extinct species.^[161] In October 2024, a 99.9% thylacine genome was sequenced from a well-preserved skull that is estimated to be 110 years old,^[12][162] allowing for the full genome of the species to be sequenced three months later.^[163]

Official usage

The thylacine has been used extensively as a symbol of Tasmania. The animal is featured on the official Tasmanian coat of arms.^[164] It is used in the official logos for the Tasmanian government and the City of Launceston.^[164] It is also used on the University of Tasmania's ceremonial mace and the badge of the submarine HMAS Dechaineux.^[164] Since 1998, it has been prominently displayed on Tasmanian vehicle number plates.^[165][166] The thylacine has appeared in postage stamps from Australia, Equatorial Guinea, and Micronesia.^[167]

Since 1996,^[168] National Threatened Species Day has been commemorated annually in Australia on 7 September, the date on which the last known thylacine died in 1936.^[169]

In popular culture

The thylacine has become a cultural icon in Australia.^[170] The best known illustrations of Thylacinus cynocephalus were those in John Gould's The Mammals of Australia (1845–1863), often copied since its publication and the most frequently reproduced,^[171] and given further exposure by Cascade Brewery's appropriation for its label in 1987.^[172] The government of Tasmania published a monochromatic reproduction of the same image in 1934,^[173] the author Louisa Anne Meredith also copied it for Tasmanian Friends and Foes (1881).^[171] The thylacine is the mascot for the Tasmanian cricket team.^[174] A series of postage stamps that feature Mickey Mouse characters with Australian animals features a thylacine stamp in the collection.^[175]

In video games, boomerang-wielding Ty the Tasmanian Tiger is the star of his own trilogy during the 2000s.^[176] Tiny Tiger, a villain in the popular Crash Bandicoot video game series, is a mutated thylacine.^[177] In Valorant, agent Skye has the ability to use a Tasmanian tiger to scout enemies and clear bomb-planting sites.^[178]

The animal has made appearance in film and television. Characters in the early 1990s' cartoon Taz-Mania included the neurotic Wendell T. Wolf, the last surviving Tasmanian wolf.^[179] The Hunter is a 2011 Australian drama film, based on the 1999 novel of the same name by Julia Leigh. It stars Willem Dafoe, who plays a man hired to track down the Tasmanian tiger.^[180] In the 2021 film, Extinct, a thylacine named Burnie, along with a group of other extinct animals, help the movie's main characters travel through time to rescue their species from extinction.^[181] In the 2022 science-fiction show The Peripheral the Tasmanian tiger is brought back into existence from DNA extracts.^[182] An animated web series titled "De-extincting Tasie" meant to explain the revival of the species by Colossal Biosciences and University of Melbourne features a thylacine named Tasie, a satire of the Mr. DNA character from the Jurassic Park media franchise.^[183]

In Aboriginal tradition

Rock art featuring thylacine-like animals are found throughout Northern Australia, particularly in the Kimberley region.^[184]

Various Aboriginal Tasmanian names for the thylacine have been recorded, such as coorinna, kanunnah, cab-berr-one-nen-er, loarinna, laoonana, can-nen-ner and lagunta,^[185][186] while kaparunina is used in Palawa kani.^[187][188]

One Nuenonne myth recorded by Jackson Cotton tells of a thylacine pup saving Palana, a spirit boy, from an attack by a giant kangaroo. Palana marked the pup's back with ochre as a mark of its bravery, giving thylacines their stripes.^[189] A constellation, "Wurrawana Corinna" (identified as within or near Gemini), was also created as a commemoration of this mythic act of bravery.^[190]

An early European record tells how Aboriginals believed bad weather was caused by a thylacine carcass being left exposed on the ground, instead of being covered by a small shelter.^[191]
