"A fossil is the preserved remains or impressions of a living organism such as a plant, animal, or insect. Some fossils are very old. Studying fossils helps scientists to learn about the past history of life on Earth. "
What is a Fossil?
Two Types of Fossils:
"Body fossils — fossils where some portion of the actual organism's body remains as part of the fossil (tooth or piece of bone). Trace fossils — fossils where there isn't any actual part of the original organism, but "traces" of the organism are preserved. (molds, animal tracks, casts, and impressions)."
Where Do We Find Them?
"Fossils are found all over the world. Most fossils are found in sedimentary rock such as shale, limestone, and sandstone."
