  • 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.[143]

(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.[149]

  • 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.[153]
  • 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.[154]
  • A study on the systematics of Devonian trochurine trilobites is published by Van Viersen (2021).[155]

  • A study on the composition and microstructure of the carapace of Chuandianella ovata is published by Liu, Fu & Zhang (2021), who interpret their findings as indicating that this arthropod reinforced its carapace with phosphatic mineralization.[173]
  • A study on the post-embryonic development of Chuandianella ovata is published by Liu, Fu & Zhang (2021).[174]
  • Braddy & Dunlop (2021) argue that Parioscorpio venator was a cheloniellid-like arthropod with large raptorial appendages.[175]

  • A study on the morphology and possible intraspecific variability of Sinoburius lunaris is published by Schmidt et al. (2021).[180]
  • A fossil larva lacking segmentation of the carapace, closely resembling the trilobite protaspis, is described from the Ordovician (Darriwilian) of central Siberia by Dzik (2021), found associated with other skeletal elements of the angarocaridid Girardevia;[181] however, Lerosey-Aubril & Laibl (2021) subsequently interpret this specimen as actually belonging to the trilobite genus Isotelus or a related taxon, and conclude that protaspid larvae represent a developmental trait unique to trilobites.[182][183]
  • A study on the possible relationships between eurypterid morphology, the ease with which members of this group experienced ecdysis, and longevity of eurypterid species is published by Brandt (2021).[184]
  • A geometric morphometric analysis of data from eurypterine eurypterid specimens is presented by Bicknell & Amati (2021).[185]
  • Redescription of Leiopterella tetliei is published by Braddy, Dunlop & Bonsor (2021).[186]
  • Bicknell, Melzer & Schmidt (2021) reconstruct prosomal appendages of Eurypterus tetragonophthalmus and Pentecopterus decorahensis, model the flexure and extension of these appendages.[187]
  • A study on the range of motion of prosomal appendages in Megalograptus ohioensis and Mixopterus kiaeri, and on its implications for the knowledge of the likely foraging strategies of these eurypterids, is published by Schmidt et al. (2021).[188]
  • Bicknell et al. (2021) report the discovery of exceptionally preserved central nervous system in a specimen of Euproops danae from the Carboniferous Mazon Creek fossil beds (Illinois, United States).[189]
  • A specimen of Euproops danae preserving anatomical details of the prosomal musculature is described from the Carboniferous Lawrence Formation (Kansas, United States) by Bicknell et al. (2021).[190]
  • Redescription and a study on the phylogenetic relationships of Prolimulus woodwardi is published by Lustri, Laibl & Bicknell (2021).[191]
  • Revision of Sloveniolimulus rudkini, based on data from new fossil material from the Anisian Strelovec Formation (Slovenia), is published by Bicknell et al. (2021).[192]

General research

  • A study on the evolution of the arthropod labrum is published by Budd (2021), who reevaluates the morphology of the Cambrian stem-euarthropod Parapeytoia and evaluates its implications for the knowledge of the origin of the labrum.[194]
  • Liu et al. (2021) report the discovery a previously undetected exite at the base of most appendages of Leanchoilia illecebrosa, as well as morphologically similar (and likely homologous) exite in the same position in Naraoia spinosa and Retifacies abnormalis, and evaluate the implications of this discovery for the knowledge of the origin of exites in arthropod phylogeny.[195]
