Aciculolenus, Wujiajiania & Labiostria Trilobites - Mckay Group
This is a cool association of three different genus of trilobites from the Mckay Group of British Columbia. The rare one of this piece is a .25" long Aciculolenus palmeri. There are also a pair of Wujiajiania on the same side of the shale and a Labiostria molt on the back of the rock.
About Trilobites
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.
