Presentation Transcript

  1. Calcite Reaction • Calcite is composed of calcium, carbon and oxygen • CaCO3 = Calcium Carbonate • Found naturally as calcite and chalk • Acid reacts and gives off carbon dioxide (CO2)

  2. Formation of limestone • Calcium carbonate becomes so concentrated in the sea water that calcite crystallizes out of the sea water to form limestone. • Most limestone forms with organisms usually found at the bottom of shallow seas.

  3. Fossil Groups Corals Bivalves Shellfish Two hinged shells Examples are clams and mussels Gastropods Snail like animals Single shell • Sea creatures • Live solitary or in colonies Brachiopods • Shellfish • Attached to sea bottom

  4. More Fossil Groups Trilobites Crinoids Known as sea lilies Marine creatures that attach to a seabed Plant Fossils Ferns are typical of floodplains and swamps • Extinct sea creatures • Earliest form of arthropod

  5. Fossil Evidence Kaibab Formation Toroweap formation Brachiopods, bryozoans 260 million years old • Braciopods/ sponges • 260 million years old

  6. Coconino Sandstone Hermit Shale Fern and insect wings 275 million years old • Fossils of animal tracks • Lizard tracks • 270 million years old

  7. Supai Group Redwall Limestone Braciopods 360 million years old • No Fossils • 325-275 million years old

  8. Temple Butte Limestone Muav Limestone Brachiopods, trilobites 530 million years old Bright Angel Shale Trilobites, burrows, tracks and trails of snails worms and trilobites 540 million years old • Primitive armored fish, conodonts • 385 Million Years Arthropods- insects, arachnids, crustatians

  9. Tapeats Sandstone Vishnu Schist No fossils 1.7 billion years old • Tubeworm burrows • 545 million years old
