Bones can decay like any other organic material. Sometimes, however, bones can be preserved in rock - those are called fossils.
Yes, fossils found in tar pits can be actual bones of prehistoric animals. The tar pits preserve organic material such as bones, teeth, and plant remains by trapping them in the sticky tar, where they can become fossilized over time. These fossils provide valuable information about past ecosystems and the creatures that inhabited them.

Some types of evidence of ancient life that can be preserved as fossils include bones, teeth, shells, footprints or trackways, and imprints of soft tissues. Plant material such as leaves, wood, and pollen can also be fossilized.
Fossils form when something dies and it decays over theyears. Thenall you see are the bones. Like dinosaurs bones!
