Photograph by James L. Amos The iconic arthropods of the Cambrian were the trilobites, which left a huge number of fossils. Trilobites had flattened, segmented, plated bodies that helped to ...

A discovery made over half a century ago in Antelope Springs, Utah, continues to raise eyebrows in the scientific community.

The most familiar and abundant species of trilobites in North America may have followed an exotic survival strategy. Elrathia kingii, found in Middle Cambrian formations in Utah, lived exclusively in ...

Focused on Cambrian fossils, the study reanimates a species long trapped in the pages of forgotten paleontology.

For over a century, the Cambrian arthropod Helmetia expansa remained a mystery. Discovered by paleontologist Charles ...
