Archaeopteris fossil plant- SphenophytaProgymnosperm Devonian through Mississippian
Ediacaran Fossils- phylum Cnidaria (?), Annelida (?) Late Proterozoic (pC)
Burgess fauna Canadia Segmented worms- Annelida- Late Precambrian to recent Polychaete worm from Mazon Creek
Burgess Fossil- Hallucigenia sparsa originally classified as an annelid (segmented worm) recently reclassified as an Onychophoran (velvet worms)
Waptia- Burgess shale fauna, an Arthropod, probably a crustacean

Sponges- Porifera, 4 Classes, (Demospongia, Hexactinellida, Calcarea, Archeocyatha, possibly Stromatoporoids), many orders From the early Cambrian to present
Crinoids and Sand dollar- Echinodermata, Crinodea and Echinoidea, and numerous Orders Cambrian to recent
Sea star and Brittle star, Echinodermata,Asteroidea and Ophiuroidea, numerous Orders Cambrian to recent
Phylum Mollusca- most numerous behind arthropods • Classes • * Aplacophora-no shells * Monoplacophera - Chitons • * Polyplacophora- 2 shelled * Scaphopoda - Tooth shells • * Gastropoda - snails * Bivalvia - clams, oysters, mussels • * Cephalopoda- octopus, squid

Snails- Mollusca, Gastropoda Cambrian to recent
Belemnite Mollusk- Mollusca, Belemnoidea, Carboniferous (Mississippian) to Tertiary
Bivalve Mollusks- e.g., clams, oysters, scallops Mollusca (Pelecypoda), Bivalvia, and 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 and other localities (e.g., China).
