• Phylum Mollusca- most numerous behind arthropods
• Classes
• Aplacophora-no shells Monoplacophera -
  Chitons
• Polyplacophora- 2 shelled Scaphopoda -
  Tooth shells
• Gastropoda - snails Bivalvia -
  clams, oysters, mussels

25
Bivalve Mollusks- e.g., clams, oysters,
scallops Mollusca (Pelecypoda), Bivalvia, and
numerous Orders Cambrian to recent
26
Tully monster - unknown systematics- possibly
Mollusca Found only in Mazon Creek Fm,
Pennsylvanian System only State Fossil!
27
Arthropod systematics- most abundant
organisms presently four Classes with many
dozens of Orders Trilobita- trilobites Chelice
rata- 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 and other
localities (e.g., China).
