Research
- Revision of the fossil record of whip spiders is published by Haug & Haug (2021).[23]
- Guo, Selden & Ren (2021) describe an adult lagonomegopid female, part of an egg sac and lagonomegopid spiderlings preserved in four pieces of Burmese amber, and interpret this finding as evidence of maternal care in fossil spiders.[24]
- An exuvium of a member of the genus Myrmecarchaea is described from the Eocene Cambay amber (India) by Wood, Singh & Grimaldi (2021), representing the first member of the family Archaeidae from Cambay amber reported to date.[25]
- An indeterminate deutonymph belonging to the family Sejidae is described by Joharchi, Vorontsov and Walter (2021) from Burmese amber, which represents the oldest record of the parasitiform mite clade Mesostigmata.[26]

Research
- A study on middle–late Cambrian trilobite diversity patterns in South China is published by Zhang et al. (2021).[139]
- Sun, Zeng & Zhao (2021) describe digestive structures of representatives of five trilobite genera from the Cambrian Mantou Formation and Zhangxia Formation (Liaoning, China).[140]
- Hou, Hughes & Hopkins (2021) report structural details of the upper limb branch of Triarthrus eatoni and Olenoides serratus, and interpret their findings as indicating that the upper limb branch of trilobites served a respiratory function.[141]
- A study on the morphology of Redlichia rex and Olenoides serratus, aiming to determine whether these trilobites were adapted for durophagy, is published by Bicknell et al. (2021).[142]
- A study exploring the existence and the nature of growth gradients along the main body axis of Oryctocarella duyunensis is published by Dai et al (2021), who interpret O. duyunensis as the first trilobite with documented determinate growth.[143]
- Description of all meraspid stages of Oryctocarella duyunensis, based on data from specimens from the Cambrian Balang Formation (Hunan, South China), is published by Dai et al. (2021).[144]
- A study on the ontogenic moulting sequence of Arthricocephalites xinzhaiheensis, based on data from specimens from the Balang Formation, is published by Wang et al. (2021).[145]
- A study on post-embryonic axial growth in Estaingia bilobata is published by Holmes, Paterson & García-Bellido (2021).[146]
- A study on the functional performance of Placoparia cambriensis in water is published by Esteve et al. (2021), who interpret their findings as indicating that this trilobite was not able to swim, but it was capable of hopping locomotion, and it might represent a transitional form between benthic animals without swimming skills and animals able to swim near the benthos.[147]
- A study on the phylogenetic relationships within Harpetida, and on the impact of the Ordovician–Silurian extinction events on this group, is published by Beech & Lamsdell (2021).[148]
- The first known Silurian trilobite specimen preserved with soft parts reported to date (a specimen of Dalmanites preserved with appendages and alimentary system) is described from the Herefordshire Lagerstätte (United Kingdom) by Siveter et al. (2021).[149]
- A study on the long-term evolutionary history of Devonian trilobites in North Africa is published by Bault et al. (2021).[150]
- A study on the hydrodynamics of queuing behaviour in Trimerocephalus chopini is published by Song et al. (2021).[151]
- Evidence from trace and body fossils indicative of the presence of trilobites in brackish-water settings is presented by Mángano et al. (2021).[152]
- A study on the chemical changes in the exoskeleton of trilobites induced by diagenesis, based on data from pygidia of Athabaskia anax from the Miaolingian of San Isidro (Argentina), is published by D'Angelo et al. (2021), is published by D'Angelo et al. (2021), who argue that some morphological characteristics of the trilobite pygidia are in fact results of chemical and structural changes taking place during fossilization, and evaluate possible systematic implications of the chemical data, advising caution when using morphological characteristics of the exoskeletons to establish new taxa.[153]
- The study on the internal structures of eyes of trilobites belonging to the genera Asaphus and Archegonus published by Scholtz, Staude & Dunlop (2019)[154] is criticized by Schoenemann & Clarkson (2021).[155][156]
- A study on the biomechanics of the trilobite cephalon is published by Esteve et al. (2021), who interpret their findings as indicating that in the sutured trilobites the cephalon was able to withstand greater stresses than in their non-sutured counterparts, and argue that the ability to withstand greater burrowing loads enabled trilobites to successfully invade bioturbated and more consolidated sediments during the Cambrian substrate revolution.[157]
- A study on the compound eyes of trilobites belonging to the group Phacopina is published by Schoenemann et al. (2021), who interpret their findings as indicating that these trilobites had hyper-compound eyes hiding an individual compound eye below each of the big lenses, resulting in each of the compound eyes comprising tens or hundreds of small compound eye systems.[158]
- A study on the systematics of Devonian trochurine trilobites is published by Van Viersen (2021).[159]
