Death-defying Morphologies: Mass Extinction and Disparity in the Order Harpetida [PDF]
The trilobite order Harpetida has long been easily recognized but poorly understood. This study seeks to better understand the phylogenetic relationships within Harpetida, with a view towards using this group to explore the relationship between ...

Los trilobites fueron artrópodos marinos paleozoicos, provistos de una cutícula dorsal mineralizada (exoesqueleto) y fosilizable, la que permitió que tengan gran representación en el registro fósil.

Modularity of a Cambrian ptychoparioid trilobite cranidium [PDF]
Modularity of the cranidium of Crassifimbra? metalaspis , a Cambrian ptychoparioid trilobite, is investigated using landmark-based geometric morphometric methods to gain insight into the integration among morphogenetic processes responsible for shaping ...

Systematics, paleobiology, and taphonomy of some exceptionally preserved trilobites from Cambrian Lagerstätten of Utah [PDF]
Mid-Cambrian biotas of the Spence, Wheeler, Marjum, and Weeks formations in Utah are exceptionally diverse. Continued collecting has produced additional trilobites here assigned to one new genus, Meniscopsia, and 25 new species.

028-Taxonomy and Preservation of Lower Cambrian Trilobites, Carrara Formation, Southern CA [PDF]
Trilobites are an extinct group of arthropods made up of three distinct body parts produced by calcite that disarticulate after molting. Trilobites lived in shallow, tropical, marine environments and left an excellent fossil record. The Cambrian is known

Rapid volcanic ash entombment reveals the 3D anatomy of Cambrian trilobites [PDF]
Knowledge of Cambrian animal anatomy is limited by preservational processes that result in compaction, size bias, and incompleteness. We document pristine three-dimensional anatomy of trilobites fossilized via rapid ash burial from a pyroclastic flow ...
