First record of Telephina (Trilobita) from the Ordovician of northeastern Estonia and its stratigraphical implications [PDF]
Estonian Journal of Earth Sciences, 2011 For the first time a telephinid trilobite was recorded from the shallow-water rocks of the North Estonian Confacies Belt in the oil-shale mining area of northeast Estonia.

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 ...

Micropollutants and the Restructuring of Microbial Resilience in the Anthropocene. [PDF]
Glob Chang BiolAnthropogenic activities continuously introduce diverse micropollutants into environmental systems through multiple pathways, generating an increasingly complex chemical background. Persistent exposure to this chemical complexity may progressively reshape microbial ecosystems, shifting the functional baseline from which microbial communities respond to

Stratigraphy and Palaeontology of Trilobites in Kuhbanan Formation in the Akbar-Abad Section (North of Kerman) [PDF]
Journal of Sciences, Islamic Republic of Iran, 2010 Cambrian sedimentary facies are exposed throughout north part of Kerman region. Trilobites’ faunas are the most common invertebrate fossils within the Cambrian strata. The section is made of 217 m of sandstone, shale, limestone and dolomite.

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 ...

Upper lower Cambrian (provisional Cambrian Series 2) trilobites from northwestern Gansu Province, China [PDF]
Estonian Journal of Earth Sciences, 2014 Upper lower Cambrian (provisional Cambrian Series 2) trilobites are described from three sections through the Shuangyingshan Formation in the Beishan area, northwestern Gansu Province, China. The trilobite fauna is dominated by eodiscoid and corynexochid

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.
