Exploring abnormal Cambrian-aged trilobites in the Smithsonian collection [PDF]
PeerJ, 2020 Biomineralised trilobite exoskeletons provide a 250 million year record of abnormalities in one of the most diverse arthropod groups in history. One type of abnormality—repaired injuries—have allowed palaeobiologists to document records of Paleozoic ...

Trilobite ‘pelotons’: possible hydrodynamic drag effects between leading and following trilobites in trilobite queues [PDF]
Palaeontology, 2017 AbstractEnergy saving mechanisms in nature allow following organisms to expend less energy than leaders. Queues, or ordered rows of individuals, may form when organisms exploit the available energy saving mechanism while travelling at near‐maximal sustainable metabolic capacities; compact clusters form when group members travel well below maximal ...

Open Research Europe, 2023 Background The Svalbard Archipelago is commonly believed to have been located at comparable latitude and, possibly, to have been attached to Laurentia in the early Paleozoic (500–420 Ma) based on trilobite assemblage similarities.

Pseudophillipsia (Carniphillipsia) (Trilobite) from the Permian Jamal Formation, Isfahan, Iran [PDF]
Journal of Sciences, Islamic Republic of Iran, 2017 The aim of this study is to bridge a gap in the existence of Trilobites in the marine Permian successions of Iran by exploring a stratigraphic section of the Permian in Jamal Formation (Dizlu section). Based on comprehensive field studies and laboratory
