Calymene Trilobites

Trilobites are arthropods which were some of the first species to develop a hard exoskeleton. Some species were also amongst the first animals to develop eyes, and in some places, they have been preserved in outstanding quality. Some had many segments, while other had very few.

Species ranged from very small species, measure less than a cm in length, to larger species, which reach over half a metre.
