Presentation Transcript

  1. Geological Range of Plants

  2. Archaeopteris fossil plant- SphenophytaProgymnosperm Devonian through Mississippian

  3. Archeapteris stump

  4. Calamites - plant

  5. Geological range of various phyla

  6. Ediacaran Fossils- phylum Cnidaria (?), Annelida (?) Late Proterozoic (pC)

  7. Burgess fauna Canadia Segmented worms- Annelida- Late Precambrian to recent Polychaete worm from Mazon Creek

  8. Burgess Fossil- Hallucigenia sparsa originally classified as an annelid (segmented worm) recently reclassified as an Onychophoran (velvet worms)

  9. Waptia- Burgess shale fauna, an Arthropod, probably a crustacean

  10. Phylum, Class, Order Rugose Coral (Horn Coral) Cnidaria, Anthozoans, Rugosa Cambrian (?) Ordovician-Permian

  11. Branching Corals, Cnidaria, Anthozoa, Tabulata Ord to Permian

  12. Scleractin Corals- Cnidaria, Anthozoa, Scleractinia Triassic to recent

  13. Triassic to recent Ord to Permian

  14. Brachiopods- Brachiopoda, 6 Classes, 25 Orders Cambrian to present

  15. Bryozoans, Lophophorata, 3 Classes, 9 Orders Early Ordovician to present

  16. Sponges- Porifera, 4 Classes, (Demospongia, Hexactinellida, Calcarea, Archeocyatha, possibly Stromatoporoids), many orders From the early Cambrian to present

  17. Crinoids and Sand dollar- Echinodermata, Crinodea and Echinoidea, and numerous Orders Cambrian to recent

  18. Sea star and Brittle star, Echinodermata,Asteroidea and Ophiuroidea, numerous Orders Cambrian to recent

  19. 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

  20. Ammonite Cephalopod- Mollusca, Cephalopoda, Ammonoidea Devonian to Cretaceous Nautiloid Cephalopod- Mollusca, Cephalopoda, Nautiloidea Cambrian to recent

  21. “Tusk” or “Tooth” shells - Mollusca, Scaphopoda Ordovician to recent

  22. Snails- Mollusca, Gastropoda Cambrian to recent

  23. Belemnite Mollusk- Mollusca, Belemnoidea, Carboniferous (Mississippian) to Tertiary

  24. Bivalve Mollusks- e.g., clams, oysters, scallops Mollusca (Pelecypoda), Bivalvia, and numerous Orders Cambrian to recent

  25. “Tully monster” - unknown systematics- possibly Mollusca Found only in Mazon Creek Fm, Pennsylvanian System only State Fossil!

  26. 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).

  27. Trilobites-Arthropoda, Trilobita, and many Orders
