Rare, 3.7" Silurian Phyllocarid (Ceratiocaris) Fossil - Scotland
This is a rare, Silurian aged Phyllocarid (Ceratiocaris papilio) collected in Scotland. It's 3.7" in length and it's exceptionally well preserved on a nice section of shale. Comes with an acrylic display stand.
Phyllocarids are a type of arthropod that developed during the Cambrian. They had a hard protective shell, hinged carapace, and were thought to have a lifestyle similar to shrimp. Exactly how they fit into the arthropod taxonomy is still under debate, with it being proposed to represent a stem-lineage euarthropod or a primitive branchiopod crustacean.
