Fossil Trilobite Paralajurus in Matrix Specimen A

Approximately 521 - 252 Million Years Old The name Trilobite means three lobed and refers to the main axial lobe which is flanked by side-ribs on the left and right, not the head, thorax, and tail that one might assume. They were one of the most common creatures of the Paleozoic era and went extinct before dinosaurs ever appeared. Their exoskeletons lent themselves easily to fossilization due to the high calcite content. Each family has distinct variations- so you can pick out one or a few that match your fossil style. Paralajurus is a genus of trilobites—those ancient, bug-like sea creatures that lived hundreds of millions of years ago.

Like other trilobites, Paralajurus crawled around the sea floor, probably scavenging for food—but who knows? Maybe it just liked hanging out at the bottom with the corals and shells. It’s got that classic trilobite look,
