Spiny Lichid (Acanthopyge) Trilobite - Insane Preparation!
This is an incredible, lichid trilobite prepared by one of the best trilobite preparitors in the world. It is a rare and stunning example of Acanthopyge from the Lhandar Formation of Morocco. This inch long trilobite is arched and has been prepared using low pressure air abrasives under high magnification to expose it from its stony tomb.
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.
