1.9" Very Rare, Spiny Heliopeltis Trilobite - Issoumour, Morocco

This is the first example of this incredible, spiny, Corynexochid trilobite that I've been able to offer. It is a 1.9" long Heliopeltis johnsoni from Issoumour, Morocco. This trilobite is literally all spines, with a very small thorax and dramatic occipital spines.

It is preserved and a counter-flexed position like every other example of the species that I have seen. There is some restoration towards the end some of the spines.

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.
