Fossils 4th Grade Educational Facts
Bold Kids
Fossils are a type of rock that contain the remains of a long-dead animal. They are used by scientists to study the history of life on Earth. These rocks can also tell scientists how ancient animals died and where they lived. There are many types of fossils. Some are found in sedimentary rock, which is formed when layers of sand, mud, and water harden over time. Sedimentary rock is often found beneath lakes and swamps.
