Zlichovaspis Trilobite & Large Leonaspis With Flying Spines

This is a very aesthetically prepared association of two different species of trilobites from Atchana, Morocco. There is a large, spiny Leonapsis, whose spines have been prepared "flying" free of the limestone. There is also a partially enrolled Zlichovaspis rugosa which would be about 3" long if outstretched. Expert preparation and excellent detail on both specimens. A very displayable piece.

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 with over 25k currently described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left an excellent fossil record.
