Bivalve Mollusks- e.g., clams, oysters, scallops Mollusca (Pelecypoda), Bivalvia, in addition to numerous Orders Cambrian to recent “Tully monster” – unknown systematics- possibly Mollusca Found only in Mazon Creek Fm, Pennsylvanian System only State Fossil! Arthropod systematics- most abundant organisms presently four Classes with many dozens of Orders Trilobita- trilobites Chelicerata- spiders, scorpions, horseshoe crabs Crustacea- crabs, shrimp, lobsters Uniramia- insects May be several other Classes that should be added, related to organisms found in the burgess shale in addition to other localities (e.g., China).

Trilobites-Arthropoda, Trilobita, in addition to many Orders
