Trilobites were a large group marine arthropods with more than 20,000 described species – related to other hard shelled creatures such as crabs, scorpions and insects. They all had jointed legs. The name trilobite refers to the 3 longitudinal divisions of a trilobites body - a central axial lobe with a pleural lobe on each side. Like modern insects, they also have 3 divisions of their body; a head or cephalon, a thorax, and a tail area or pygidium.

These fascinating ancient creatures lived throughout most of the Paleozoic Era, for about 300 million years. The earliest species date back to the Cambrian Period, about 520 million years ago. They are grouped into 10 distinct Orders, which are extremely varied, ranging in size from just over 1 mm to 720 mm. Some types were covered in spectacular curving spines.
