The paper reports a healed predation scar on a Cambrian apex predator, providing evidence of trophic complexity in Cambrian food webs.

This study uses morphometric analysis to resolve a long-standing taxonomic debate about two Upper Ordovician arthropods, placing them within Vicissicaudata.

This study uses 3D modeling to evaluate the planktonic lifestyle of the Silurian trilobite Deiphon by analyzing its morphology and buoyancy.

This study quantifies the hierarchical importance of factors affecting trilobite cephalic disparity using Linear Mixed-Effects Models and finds family-level classification better explains morphometry than order-level or other variables.

The paper analyzes trilobite cephalic morphology across the Palaeozoic to determine factors driving morphological disparity and its temporal variation.

The paper examines the evolution of dorsal ecdysial sutures in trilobites and their relatives, finding that their origin is ambiguous and may be either ancestral or convergent.

This study uses computational fluid dynamics to show that genal prolongations in trinucleimorph trilobites generated negative lift, helping them stay on the seafloor in fast-flowing water.
