PseudoarctolepisDescription: This unusual Phyllocarid arthropod is known as Pseudoarctolepis sharpi. Phyllocarids are one of the lesser known branchiopod crustaceans from the Cambrian where they are among the earliest animals with a hard shell. They have a fairly large carapace, which protects the anterior part of the body. This structure hinged along the dorsal edge like a bivalve. Usually only the carapace is found. This one has both of the stabilizing arms preserved.
