Paragraph: (Science-textbook/science-g3-37.txt)
Sent 1: Fossils may form in other ways.
Sent 2: Fossils can be preserved almost completely.
Sent 3: In this process, the organism doesnt change much.
Sent 4: As seen below, tree sap may cover an organism.
Sent 5: With time, the sap hardens.
Sent 6: It turns to into amber.
Sent 7: The original organism is preserved.
Sent 8: This is very exciting for scientists.
Sent 9: They are able to study the DNA of the organism that no longer lives on Earth.
Sent 10: Some animals have been found frozen in ice.
Sent 11: Others have been found in tar pits after falling in.
Sent 12: Molds and casts are another way organisms can be fossilized.
Sent 13: Have you ever walked in soft mud and left footprints?
Sent 14: Once in a while, these traces of organisms can be preserved.
Sent 15: In this case, nothing is left of the organism.
Sent 16: A mold is an imprint of an organism that is preserved in rock.
Sent 17: The organisms remains break down completely.
Sent 18: There is nothing left of the original plant and animal.
