Implications of Timanian thrust systems in the Barents Sea and Svalbard on using paleontological constraints for plate tectonics reconstructions [version 2; peer review: 1 approved, 2 approved with reservations] [PDF]
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.

Geophysical Monograph Series, Page 435-447., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

The median eyes of trilobites [PDF]
Scientific Reports, 2023 AbstractArthropods typically possess two types of eyes—compound eyes, and the ocellar, so called 'median eyes'. Only trilobites, an important group of arthropods during the Palaeozoic, seem not to possess median eyes. While compound eyes are in focus of many investigations, median eyes are not as well considered.

Crawlers on the Seabed – The Famous Devonian Trilobites of Gerolstein [PDF]
Geoconservation Research, 2021 This paper introduces the Middle Devonian trilobites of Gerolstein, found on the famous trilobite fields of Gees and at the Auberg hill in Gerolstein.

The oldest known digestive system consisting of both paired digestive glands and a crop from exceptionally preserved trilobites of the Guanshan Biota (Early Cambrian, China). [PDF]
PLoS ONE, 2017 The early Cambrian Guanshan biota of eastern Yunnan, China, contains exceptionally preserved animals and algae. Most diverse and abundant are the arthropods, of which there are at least 11 species of trilobites represented by numerous specimens.

Discovery of trilobite trace fossils from the Early to Middle Cambrian, Tabas Block, Central Iran [PDF]
Journal of Stratigraphy and Sedimentology Researches, 2017 Early to Middle Cambrian successions exposed at the Shirgesht area, Tabas Block of central Iran has yielded a high diversity and abundant ichnofossils with arthropod trackways. These trace fossils contain diverse ethological patterns, including furrowing

Coupled exuviae of the Ordovician Ovalocephalus (Pliomeridae, Trilobita) in South China and its behavioral implications [PDF]
PeerJ, 2020 Ecdysis was a vital process during the lives of trilobites. In addition to preserving the morphological changes in trilobite ontogeny, the preservation of its action often captured interesting behavioral information.

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.
