Arachnid research
- Shanks & Selden (2022) describe the first trigonotarbid specimens from the Carboniferous Shelburn Formation of Indiana and Senora Formation of Oklahoma.[26]
- A study on the anatomy of Protoischnurus axelrodorum is published by Carvalho et al. (2022), who interpret this scorpion as a probable early member of the crown group of Iurida, possibly a stem hormurid.[27]
- Xuan, Cai & Huang (2022) describe two immature scorpions from the Cretaceous amber from Myanmar, assigned to the genus Chaerilus.[28]
- Revision of recluse spiders from the Dominican amber is published by Magalhaes et al. (2022), who transfer the species "Loxosceles" aculicaput to the family Drymusidae and to the genus Drymusa.[29]

Trilobite research
- A study on patterns of segment allocation and expression in the bodies of trilobites throughout their evolutionary history is published by Hopkins & To (2022), who argue that neither taxonomic turnover nor enrolment behaviour of trilobites can sufficiently explain the studied changes of segmentation patterns.[133]
- A study on the early evolutionary history of trilobites is published by Holmes & Budd (2022), who argue that the first appearance datum of trilobites in the fossil record closely reflects their evolutionary origins, and that there is no compelling evidence to suggest an extended cryptic evolutionary history for this group.[134]
- Bicknell et al. (2022) describe malformed trilobite specimens from the Cambrian Beetle Creek Formation (Llanfawr Mudstones (Wales, United Kingdom), and attempt to determine the origin of the studied injuries.[135]
- A study on the injured specimens of Redlichia takooensis and Redlichia rex from the Cambrian Emu Bay Shale (Australia) is published by Bicknell et al. (2022), who argue that R. rex was likely the chief producer of the injuries in the studied specimen and of large shelly coprolites in the Emu Bay Shale biota, and represents one of the earliest cannibalistic trilobites.[136]
- Losso & Ortega-Hernández (2022) report evidence of the presence of significantly modified and reduced
- A study on the phylogenetic relationships of members of the olenid group Hypermecaspidinae is published by Monti, Tortello & Confalonieri (2022).[138]
- Revision of Ordovician trilobite collections from Shan State (Myanmar) and Yunnan (China), first described by F.R.C. Reed, is published by Fortey, Wernette & Hughes (2022).[139]
- A study on the growth and mortality of Triarthrus eatoni, reevaluating the data presented by Cisne (1973),[140] is published by Pauly & Holmes (2022).[141]
- Edgecombe & Fortey (2022) describe a specimen of Asaphellus tataensis from the Fezouata Formation (Morocco) preserved with antennae bearing a series of round, dome-shaped organs of uncertain homology and function, larger than sensilla on the antennae of other arthropods.[142]
- A study on the degree and structure of modularity in the heads of Calyptaulax annulata and Cloacaspis senilis is published by Vargas-Parra & Hopkins (2022), who consider the best modularity models to be those in which the eyes and anteriormost cranidium formed a single module, or belonged to two modules that highly covaried relative to other modules.[143]
- Bicknell & Smith (2022) seven new abnormal specimens of Odontopleura (Sinespinaspis) markhami from the Silurian (Telychian) Cotton Formation (Australia), interpreting their abnormalities as teratological developments through genetic malfunctions, and evaluate likely causes of abnormalities in Silurian trilobite specimens in general.[144]
- A study on the distribution patterns of Devonian trilobites from Morocco and northwestern Algeria through time and space is published by Bault, Crônier & Bignon (2022).[145]
- A study on the morphological diversity and possible relationship between morphology and environmental and/or ecological factors in Devonian trilobites from North Africa is published by Bault, Crônier & Monnet (2022).[146]

- Biomechanical study of the chelicerae of pterygotid eurypterids is published by Bicknell et al. (2022), who argue that pterygotid chelicerae were functionally analogous to scorpion chelae, and that Erettopterus bilobus and Pterygotus anglicus had a generalised diet and were apex predators of their ecosystems, while Acutiramus bohemicus was adapted to piercing and slicing the cuticle of other eurypterids, and Jaekelopterus rhenaniae was adapted to capturing large, highly mobile, armoured prey.[178]
