Trilobites[]

Research[]

A study on the rates of evolution of trilobites in the Cambrian is published by Paterson, Edgecombe & Lee (2019), who interpret their findings as indicative of Cambrian rather than Precambrian origin of trilobites, and as indicating that the Cambrian explosion had already largely concluded by the time the typical Cambrian fossil record begins (∼521 Ma).^[107]
A study on repaired injuries in trilobite specimens from the Cambrian Ruin Wash Lagerstätte (Nevada, United States) is published by Pates & Bicknell (2019), who interpret their findings as indicative of species specific predation on Cambrian trilobites, and of enlarged spines in some trilobite species serving as possible predation deterrents.^[108]
A study on the morphology and ontogeny of Changaspis elongata, based on data from specimens from the Lazizhai section of the Balang Formation (Cambrian Stage 4; Guizhou, China), is published by Du et al. (2019).^[109]
A cluster of over a 100 juvenile trilobites belonging to the genus is reported from the Cambrian (Paibian) Conasauga Formation (Georgia, United States) by Schwimmer & Montante (2019).^[110]
A study on patterns of occupancy and diversity trajectories in late Cambrian-early Ordovician trilobite communities from the Argentine Cordillera Oriental is published by Serra, Balseiro & Waisfeld (2019).^[111]
A study on the phylogenetic relationships of members of the family Olenidae is published by Monti & Confalonieri (2019).^[112]
A study on the phylogenetic relationships of members of the olenid subfamily is published by Hopkins (2019).^[113]
Nine specimens of ebbestadi preserving all key stages of the exoskeleton moulting process are described from the Lower Ordovician Fezouata Formation (Morocco) by Drage et al. (2019).^[114]
A study on clusters of Ampyx priscus from the Ordovician Fezouata Shale of Morocco is published by Vannier et al. (2019), who interpret these clusters as evidence of a collective behaviour rather than a result of passive transportation and accumulation.^[115]
A study on the phylogenetic relationships of the species and subspecies assigned to the phacopid genus is published by Oudot et al. (2019).^[116]
A study on the morphological changes in the ontogeny of the Ordovician phacopid trilobite Calyptaulax strasburgensis is published by Jacobs & Carlucci (2019).^[117]
A well-preserved body cluster of 18 specimens of Arctinurus boltoni is described from the Silurian Rochester Shale (New York, United States) by Bicknell, Paterson & Hopkins (2019).^[118]
A study on development and evolution of the cephalon and the pygidium in phacopid trilobites is published by Oudot et al. (2019).^[119]
A study on the internal structures of eyes of trilobites belonging to the genera Asaphus and is published by Scholtz, Staude & Dunlop (2019);^[120] the study is subsequently criticized by Schoenemann & Clarkson (2021).^[121]^[122]
A study on the variability of trilobite moulting behaviour is published by Drage (2019).^[123]

Description of new bradoriid fossils from the Chengjiang biota, revealing hitherto unknown morphological differences in limb anatomy between bradoriid species, is published by Zhai et al.
