3.1" Crotalocephalus Trilobite With Three Reedops - Atchana, Morocco

Crotalocephalus Trilobite With Three Reedops - Atchana, Morocco #210265

This is a really displayable piece from the Lhandar Formation of Morocco. There are four trilobites, present on this aesthetically sculpted block of limestone. The largest trilobite is a 3.1" long Crotalocephalus, not to be confused with the common Crotacephalina from the same formation. They can be distinguished by the longer tail spines in Crotalocephalus. There are also three Reedops trilobites present on the piece. The base of the rock is fairly flat so it displays nicely without the need for a display stand.

Trilobites were a very diverse group of extinct marine arthropods. They first appeared in the fossil record in the Early Cambrian (521 million years ago) and went extinct during the Permian mass extinction (250 million years ago). They were one of the most successful of the early animals on our planet: over 25,000 species have been described, filling nearly every evolutionary niche. Due in large part to their hard exoskeletons (shells), they left an excellent fossil record.
