Malacostracan research

• Description of the fossil material of members of Pygocephalomorpha from the Carboniferous Piesberg quarry (Lower Saxony, Germany), including a record of Anthracaris gracilis which was previously reported from the Mazon Creek fossil beds (Illinois, United States) and from Bickershaw (Lancashire, United Kingdom), and a study on the distribution of eumalacostracan crustaceans from Carboniferous deposits of North America and Europe is published by Pazinato et al. (2022).
• Redescription of Oncopareia bredai and a revision of other species previously referred to the genus Oncopareia is published by Tshudy et al. (2022).
• A study on the evolution of carapace morphology of hermit crabs and changes of composition of their assemblages through time is published by Fraaije et al. (2022), who reinstate Probeebeidae as a distinct family, and name a new family Paguropsidae.
• A study on sexual dimorphism and intersex specimens in the population of hundreds of specimens of the Cretaceous crab Dakoticancer overanus Jones, Schweitzer & Feldmann (2022).
• Ossó et al. (2022) report the first known fossil material of Pleolobites from the Paleocene (Thanetian) of Togo, and reevaluate the phylogenetic affinities of this and other fossil portunoid crabs.
• A concretion containing an adult and a juvenile individual of Trichopeltarion greggi, representing the first association of an adult female and a juvenile crab of the same species in the fossil record reported to date, is described from the Miocene Greta Siltstone (New Zealand) by Feldmann & Schweitzer (2022), who interpret this finding as possible evidence of maternal care of juveniles.

Other crustacean research

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.
• 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.
• Bicknell et al. (2022) describe malformed trilobite specimens from the Cambrian Beetle Creek Formation (Australia), Chisholm Formation (Nevada, United States) and Wheeler Formation (Utah, United States) and from the Ordovician Llanfawr Mudstones (Wales, United Kingdom), and attempt to determine the origin of the studied injuries.
• 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.
• Losso & Ortega-Hernández (2022) report evidence of the presence of significantly modified and reduced endopodites underneath the seventh thoracic and first pygidial tergites of Olenoides serratus and interpret these appendages as likely functional analogs to claspers.
• A study on the phylogenetic relationships of members of the olenid group Hypermecaspidinae is published by Monti, Tortello & Confalonieri (2022).
• 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).
• A study on the growth and mortality of Triarthrus eatoni, reevaluating the data presented by Cisne (1973), is published by Pauly & Holmes (2022).
• 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.
• 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.
• 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.
• 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).
• 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).
• A study on changes in global distribution of trilobites during the late Paleozoic is published by Brezinski (2022).

• Redescription of Triopus draboviensis is published by Van Roy, Rak & Fatka (2022), who also provide a revised diagnosis for Cheloniellida, and exclude Parioscorpio venator from this clade.
• Redescription of the ventral morphology of Retifacies abnormalis and a study on the implications of this taxon for the knowledge of the relationships and evolution of Cambrian artiopods is published by Zhang et al. (2022).
• A study on the appendicular organization in Pygmaclypeatus daziensis and on its ecological and evolutionary implications is published by Schmidt et al. (2022).
• Description of the organization of the central nervous system of a specimen of Mollisonia symmetrica from the Burgess Pass (Burgess Shale; British Columbia, Canada) is published by Ortega-Hernández et al. (2022).
• A study on the evolutionary stability in the history of fossil and living xiphosurids is published by Bicknell et al. (2022).
• Revision of Australian xiphosurids Austrolimulus fletcheri, Dubbolimulus peetae, Tasmaniolimulus patersoni and Victalimulus mcqueeni, and a study on the temporal range of these taxa is published by Bicknell et al. (2022), who reinterpret T. patersoni as living in the Triassic rather than Permian.
• New specimen of Vaderlimulus tricki, providing new information on the anatomy of this xiphosuran and representing the first record of muscles in an austrolimulid reported to date, is described from the Olenekian Thaynes Group (Idaho, United States) by Lerner & Lucas (2022).
• A study on the ontogenetic stages, allometry and ecology of Paleolimulus kunguricus is published by Naugolnykh & Bicknell (2022).
• A study on the anatomy of the chelicerae of Slimonia acuminata, based on data from a new specimen, is published by Lamsdell (2022).
• Braddy & Gass (2022) redescribe tracks from the Ordovician Martinsburg Formation (New York, United States) assigned to the ichnotaxon Palmichnium gallowayi, attribute these tracks to a medium-sized stylonurid eurypterid, and interpret them as the earliest trace fossil evidence for mass migrations of eurypterids into nearshore environments to molt and mate.
• 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.
• New fossil material of Tuzoia with exceptionally preserved soft tissues is described from the Cambrian Burgess Shale (Canada) by Izquierdo-López & Caron (2022), who interpret this arthropod as adapted to predation or scavenging while swimming along the seafloor, and interpret it as an early member of Hymenocarina.
• A study on the functional morphology of Ercaicunia multinodosa, aiming to determine the posture used by this arthropod to overcome resistance and to obtain most lift while sliding in the water column, is published by Li et al. (2022).
