List of Australian and Antarctic dinosaurs
Valid genera
| Name | Year | Formation | Location | Notes | Images |
|---|---|---|---|---|---|
| Antarctopelta | 2006 | Snow Hill Island Formation (Late Cretaceous, Maastrichtian) | Antarctica | Possessed unusual caudal vertebrae that may have supported a "macuahuitl" as in Stegouros[1] |  |
| Atlascopcosaurus | 1989 | Eumeralla Formation (Early Cretaceous, Aptian to Albian) |  Australia |
Only known from remains of jaws and teeth |  |
| Australotitan | 2021 | Winton Formation (Late Cretaceous, Cenomanian to Turonian) | Australia |
The largest dinosaur known from Australia, comparable in size to large South American dinosaurs. Potentially a synonym of the contemporary Diamantinasaurus[2] |  |
| Australovenator | 2009 | Winton Formation (Late Cretaceous, Cenomanian) | Australia |
Analysis of its arms suggests it was well-adapted to grasping[3] |  |
| Austrosaurus | 1933 | Allaru Formation (Early Cretaceous, Albian) | Australia |
Its holotype was found associated with marine shells |  |
| Cryolophosaurus | 1994 | Hanson Formation (Early Jurassic, Pliensbachian) | Antarctica | Had a distinctive "pompadour" crest that spanned the head from side to side | .jpg) |
| Diamantinasaurus | 2009 | Winton Formation (Late Cretaceous, Cenomanian) | Australia |
May have been closely related to South American titanosaurs, suggesting they dispersed to Australia via Antarctica[4] |  |
| Diluvicursor | 2018 | Eumeralla Formation (Early Cretaceous, Albian) | Australia |
Lived in a prehistoric floodplain close to a high energy river |  |
| Fostoria | 2019 | Griman Creek Formation (Late Cretaceous, Cenomanian) | Australia |
Four individuals have been found in association |  |
| Fulgurotherium | 1932 | Griman Creek Formation (Late Cretaceous, Cenomanian) | Australia |
Fragmentary, but may have been an elasmarian[5] |  |
| Galleonosaurus | 2019 | Wonthaggi Formation (Early Cretaceous, Barremian) | Australia |
Its upper jaw bone resembles a galleon when turned upside down |  |
| Glacialisaurus | 2007 | Hanson Formation (Early Jurassic, Pliensbachian) | Antarctica | Basal yet survived late enough to coexist with true sauropods[6] |  |
| Imperobator | 2019 | Snow Hill Island Formation (Late Cretaceous, Maastrichtian) | Antarctica | Initially described as a basal paravian although it may potentially be a unenlagiine[7] |  |
| Kakuru | 1980 | Bulldog Shale (Early Cretaceous, Aptian) | Australia |
Poorly known |  |
| Kunbarrasaurus | 2015 | Allaru Formation, Toolebuc Formation (Early Cretaceous, Albian) | Australia |
Preserves stomach contents containing ferns, fruit and seeds[8] |  |
| Leaellynasaura | 1989 | Eumeralla Formation (Early Cretaceous, Aptian to Albian) | Australia |
One referred specimen has an extremely long tail. If it does belong to this genus, it would be three times as long as the rest of the body |  |
| Minmi | 1980 | Bungil Formation (Early Cretaceous, Aptian) | Australia |
Had long legs for an ankylosaur, possibly to help it run into bushes for protection[9] |  |
| Morrosaurus | 2016 | Snow Hill Island Formation (Late Cretaceous, Maastrichtian) | Antarctica | Closely related to Australian and South American ornithopods[5] |  |
| Muttaburrasaurus | 1981 | Allaru Formation, Mackunda Formation (Early Cretaceous to Late Cretaceous, Albian to Cenomanian) | Australia |
Possessed a short oval bump on its snout originally thought to have been a sound chamber although it is now believed to belong to a modified premaxilla[10] |  |
| Ozraptor | 1998 | Colalura Sandstone (Middle Jurassic, Bajocian) | Australia |
Potentially the oldest known abelisauroid[11] |  |
| Qantassaurus | 1999 | Wonthaggi Formation (Early Cretaceous, Barremian) | Australia |
Distinguished from other contemporary ornithopods by its relatively short dentary |  |
| Rapator | 1932 | Griman Creek Formation (Late Cretaceous, Cenomanian) | Australia |
Known from only a metacarpal |  |
| Rhoetosaurus | 1926 | Walloon Coal Measures (Late Jurassic, Oxfordian) | Australia |
Retains four claws on its hind feet, a basal trait |  |
| Savannasaurus | 2016 | Winton Formation (Late Cretaceous, Cenomanian to Turonian) | Australia |
May have spent more time near water than other sauropods[12] |  |
| Serendipaceratops | 2003 | Wonthaggi Formation (Early Cretaceous, Aptian) | Australia |
Possessed a robust ulna similar to that of ceratopsians and ankylosaurs, but was likely a member of the latter group[13] | |
| Timimus | 1993 | Eumeralla Formation (Early Cretaceous, Albian) | Australia |
Potentially a tyrannosauroid.[14] If so, it would be one of the few Gondwanan members of that group |  |
| Trinisaura | 2013 | Snow Hill Island Formation (Late Cretaceous, Campanian) | Antarctica | The first ornithopod named from Antarctica |  |
| Weewarrasaurus | 2018 | Griman Creek Formation (Late Cretaceous, Cenomanian) | Australia |
Unusually, its fossils were preserved in opal |  |
| Wintonotitan | 2009 | Winton Formation (Late Cretaceous, Cenomanian) | Australia |
More gracile than other contemporary titanosaurs |  |
Invalid and potentially valid genera
- Agrosaurus macgillivrayi: Although originally reported as being from Australia, it may actually be from Europe, possibly being synonymous with Thecodontosaurus.
- "Allosaurus robustus": Originally described as a new species of Allosaurus, but may actually represent a megaraptoran or abelisauroid.
- "Biscoveosaurus": Said to be a large ornithopod contemporary with Morrosaurus.
- Walgettosuchus woodwardi: It has been considered synonymous with Rapator, but too little is known of both genera to be certain.
