All about Fossils
A fossil is the preserved remains or traces of something that lived long ago. Fossils are usually found in sedimentary rock. They can be bones, teeth, shells, footprints or even droppings that have turned to stone over millions of years.
Fossils form when a living thing is buried quickly by mud or sand, so soft parts decay but minerals seep in and replace the hard parts.
Fossils are like clues from the past. By studying them, scientists learn what animals looked like, what they ate and how the climate has changed.
