Trilobite Fossils

It is difficult for even the true trilobite enthusiast to explain the almost mystical appeal that these amazingly diverse organisms hold over them.

Trilobites were sea creatures and lived in very shallow water to very deep water, although some existed on land. Most fossilised remains of trilobites are always found in rocks containing fossils of other salt-water animals such as brachiopods, crinoids, and corals. Trilobite means, “Three lobes.” referring to their body sections. They are most closely related to modern horseshoe crab and moult their exoskeleton much like crabs.


Trilobites, first appeared at the beginning of the Cambrian Period, about 542 million years ago and became quite abundant with over 20,000 variations before becoming extinct in the Permian Period about 251 million years ago.
