What Are Fossils?

Fossils are the remains or traces of ancient life. Fossils can be mineralized bones, teeth, shells, wood, or actual unaltered material from an organism, like frozen mammoth flesh, bones and fur. Eggs, nests, footprints, leaf impressions, burrows, and feces are examples of trace fossils. One thing all fossils have in common, they are OLD, at least 10,000 years old.
