  1. Fossils!

  2. What are fossils? • Fossils are the preserved remains of a living thing that died.

  3. Different types of fossils! • There are 6 main types of fossils!! • Mold Fossils • Cast Fossils • True Form Fossils • Carbon Films • Trace Fossils • Body Fossils

  4. Mold Fossils • The imprint or impression of a living thing • Form after hard parts have been buried and then dissolved by water Photo Credit: edt907finalproject.wikispaces.com

  5. Cast Fossils • Form when a mold is filled in with a mineral Photo Credit: ykonline.yksd.com

  6. Carbon Films • Look like images or pictures! • Created when every part of an organism decays or dissolves except the carbon. Photo credit: www.studydroid.com

  7. Trace Fossils • Formed when an organism leaves an imprint and that imprint is filled with minerals or another substance like volcanic ash. • Teeth marks, prints, nests, and more! Photo Credit: www.bbc.co.uk

  8. True Form Fossils • A fossil of the entire body of an organism • Formed when the organism’s tissues or hard parts did not decay Photo credit: silentkiller6.glogster.com

  9. Body Fossils • Usually teeth and bones turned to stone • Minerals harden the bones or sometimes replace the actual bone itself and just make it a stone Photo credit: quizlet.com

  10. Fossilization? • Sediment • Layers (minerals) • Movement • Erosion Photo credit: jpostema.napsk12.org

  11. Unaltered Preservation • Amber, tar, ice • True form fossils! Photo Credit: ngm.nationalgeographic.com

  12. Permineralization/ Petrification • Minerals seep in and replace the original tissues • Creates a rock-like fossil • Most dinosaur fossils are made from this! • Body fossils! Photo Credit: www.dailysciencefix.com

  13. Carbonization • The carbon inside the thing that died stays • Carbon films! Photo Credit: www.newark.osu.edu

  14. Authigenic preservation • Molds or casts! Photo credit: petrifiedwoodmuseum.org

  15. Fossil Record • By looking at a fossil we can learn so much about the earth!! Photo credit: www.globalchange.umich.edu
