Presentation Transcript

  1. Chapter 6 – The Rock and Fossil Record http://youtu.be/ClJ5lwl_wM0 3 ½ min Fossil Rock Anthem PALEONTOLOGY the study of fossils or past life “paleo” means old or ancient

  2. EXTINCT • Extinction is the death of every member of a species. • To be extinct means to be no longer on this Earth. Woolly Mammoth Dodo bird Saber Tooth Tiger Quagga

  3. FOSSIL the preserved remains, traces, or imprint of an organism http://youtu.be/Zo49Pyhii-k 3 min  BBC – Earth’s rarest and ancient fossils http://www.youtube.com/watch?v=3rkGu0BItKM&feature=share&list=PLOxx_Ap1N_kcgyHcmqdi5cnYRNuihA8Mw 2 ½ min  What are fossils

  4. BODY FOSSIL The actual remains of an organism, including bones, shells, teeth, and seeds.

  5. http://youtu.be/068GcVD3VaE 5 min  Petrified Forest National Park PETRIFACTION The process by which the organic material of an organism is replaced with hard minerals. Petoskey rock – fossilized coral from Michigan petrified dinosaur bone agate (rock)

  6. MOLD The imprint or shape (empty space) left by an organism’s body or movements.

  7. CAST A mold left by an organism’s body or movements that has been filled with minerals or sediment. The cast forms inside the mold.

  8. AMBER Insects, frogs, lizards and plants have been preserved in soft, sticky tree sap. Overtime, the sap hardens into amber, which can be used in jewelry.

  9. TRACE FOSSILS Details preserved in rock provide info about the activities of prehistoric animals, including animal tracks, trails, burrows, and nest. Animals burrowed through the soft sediment at the bottom of the ancient seas. Amphibian tracks

  10. http://youtu.be/nBfMa62fkHA 3 ½ min La Brea Tar Pits La Brea Tar Pits The extinct animals discovered at Rancho La Brea were trapped in the asphalt (tar) between 11,000 to 50,000 years ago. They may have lived in the Los Angeles region for much of the last 100,000 years. Before that time the Los Angeles Basin was covered by the Pacific Ocean. Asphalt is very sticky, particularly when it is warm. Small mammals, birds, and insects that would come into contact with it would be immobilized as if trapped like flies on flypaper.

  12. A Time Line of Earth’s Past http://youtu.be/zklzOjmz7Wk 5 min  The Ages of Rock/Fossils RELATIVE AGE The age of a fossil or layer of rocks as compared to other fossils and rock layers found above and below it. Scientists can use the order of layers to find relative age of a fossil. The lower layers in the rock are older because they settled first. Newer layers formed on top of the older layers.

  13. ABSOLUTE AGE The exact numerical age of a fossil. Dating fossils have helped scientists explain the theory of continental drift.

  14. Using Fossils to Date Rock INDEX FOSSILS Are well-known organisms that lived a short time and then became extinct. AmmoniteTrilobite marine mollusk related to horseshoe crab By dating the rock layers above and below these fossils, scientists can determine the time span in which the organisms that formed the fossils lived.

  15. Georgia State Fossil Petrified shark tooth Georgia designated the shark tooth as the official state fossil in 1976. A fairly common fossil on the Georgia coastal plain, the fossilized shark tooth is prized by collectors. These prehistoric shark teeth are found in a range of colors - most common are black or gray, less common are the white, brown, blue, and reddish-brown teeth. Many types of sharks lived in prehistoric Georgia - the oldest teeth date back about 375 million years. One of the largest extinct species of shark was Otodontidae Carcharocles megalodon.

  16. Time Marches On… A unit of geologic time Era - Paleozoic Era • “Paleo” means ancient, old or in the past • “Zoic” means life or animal • Marine life was abundant. • Ended with the largest mass extinction http://youtu.be/XdeYhMd5RDM 4 min Paleozoic Era http://youtu.be/FlUes_NPa6M 10 ½ min Mass Extinctions

  17. Mesozoic Era • “Meso” means middle • Age of Reptiles • Small mammals appeared • Another mass extinction occurred at end of the era.

  18. Cenozoic Era • “Ceno” means recent • Began 65 million years ago • Continues to present time • Age of Mammals

  19. Mammals • Mammals had unique adaptations that may have helped them to survive climate change: • Regulating body temperature (warm-blooded) • Bearing young that developed inside the mother • Dinosaurs were unable to adapt which caused their disappearance from Earth (cold-blooded and egg-laying).
