  1. The Fossil Record SC-07-3.5.1 Learning Objectives Be able to describe the fossil record and knowledge gained from studying them List evidence to explain reasons why the fossil record is incomplete Be able to explain why ocean fossils can be found on mountain tops

  2. Starter An animal or plant had to be very "lucky" to become a fossil, and even luckier to have its fossil remains discovered. Fossilization is an infrequent occurrence that is highly dependent on chance. In the past, like today, the remains of most organisms were eaten by animals, consumed by microorganisms, or weathered away. Only dead organisms that are buried in sediment quickly can escape these destructive natural processes and become fossils. After remains have been buried and preserved, they may still be destroyed by geological processes, or exposed and weathered away before people can find them.

  3. Organisms that were very rare in their environment might never have been fossilized simply because the odds of preservation favor more numerous organisms. Animals with small and delicate bones, such as small birds and amphibians, would be less likely to be preserved - and discovered - than larger organisms with tougher bones. Soft-bodied organisms like worms are even more poorly represented in the fossil record because they had no hard parts that could resist decay. We usually learn of their existence only if we find fossilized burrows, or trackways or impressions left by their bodies in soft sediments. Scientists studying ancient ecosystems such as this one try to collect fossils from as many types of organisms as possible, but they never expect to find fossil evidence of everything that lived there. THINK ABOUT IT- Is the fossil record complete? Review the evidence you just read and list details to support you choice.

  4. How to become a fossil... … well, first the organism has to die... Then it must be lucky enough to land near water so the fossilization process can occur... Watch the video below to learn more, you will need to summarize if a fossil is still bone or has changed into something else...

  5. Interpreting the fossil record Visit the link below to help answer the questions listed on your organizer/study guide The Fossil Record SKIM the top section, but begin reading at “How reliable is the fossil record”. While reading, pay close attention to details that may help explain why the fossil record has been compared to a giant jigsaw puzzle and what fossils tell us. How can the fossil record tell us about environmental conditions of the past?

  6. Ocean fossils on a mountaintop... FOR REAL??? That’s crazy... Or is it?? Read the article link below to help solve the mystery of how ocean fossils can be found on mountaintops The New York Times: WHALE FOSSILS HIGH IN ANDES SHOW HOW MOUNTAINS ROSE FROM SEA
