The many different ways organisms are preserved gives fossils different characteristics. Permineralization is when an organism dies and sediment enters the body, filling in the pores of a leaf, or a bone or a shell.Oftentimes, minerals from the sediment will eventually replace the organism's tissues, leaving a replica of the original organism.Free 5-day trial Fossils provide scientists with many clues about Earth's history, offering evidence of dinosaurs and strange plants that existed in the past.This lesson will define a fossil, look at different types and characteristics of fossils, and then describe how fossils are formed.

Many things can happen at this point: the Hadrosaur can dissolve, leaving a mold or cast fossil behind, or minerals can permeate the bone, leaving a permineralization fossil.

Fossilization, or fossil formation, is actually pretty rare.

The right organism has to be in the right place at the right time.

Let's use a Hadrosaur as an example to explore the world of fossilization.

The Hadrosaur is happily walking along a riverbank when a mudslide occurs, killing and burying him.
