How are fossil found?

Fossils are usually found in sedimentary rock, which formed near prehistoric rivers. Some are buried deep underground, but others are discovered when wind or rain removes just a thin layer of dirt. Mary Anning discovered many fossils that had been revealed by landslides.

How do fossils help us?

Fossils of any kind are useful in “reading the rock record,” meaning they help us decipher the history of the earth. They can help us determine the geologic age and environment (the paleoenvironment) in which they were deposited.

Fossils are the preserved remains, or traces of remains, of ancient organisms. Fossils are not the remains of the organism itself! They are rocks.

However, if you want your remains to become a fossil that lasts for millions of years, then you really want minerals to seep through your bones and replace them with harder substances. This process, known as ‘permineralisation’, is what typically creates a fully-fledged fossil. It can take millions of years.

fossils and the remains of vertebrate animals (those with a backbone). The US federal land laws forbid any collection of vertebrate fossils without an institutional permit, but allow hobby collection of common invertebrate and plant fossils on most federal land , and even commercial collection of petrified wood.
