Transcript of Fossils
Study of prehistoric time/life
remains preserved in rock
Fossil record is not complete due to weathering
Evidence the organism was there (not a part of it)
EX. foot prints, coprolite (poop), bite marks
1) Lived a short time
3) Abundant (lots of them)
4) Easy to identify
Original vs Replaced Remains
Identify the following as original or replaced
EQ: How do different types of fossils form?
Fossils are found in sedimentary rocks
Why? because they form under low heat
Empty space left behind by an organism
3D replica (formed inside mold)
Can you ID these fossils as molds and casts
Hard parts (bones, teeth) are replaced by minerals
The Actual Remains
Ex. amber (tree sap) and frozen in ice
Frozen mammoth hair
Terror bird's bone minerized
lizard stuck in tree sap
Identify the type below
steps of fossil formation
Soft parts rot or decompose
bones and teeth are buried under sediment
Remains are replaced with minerals and turned into rock
