What is carbonization of fossils?

Carbonized fossil remains (also called carbonizations) may result when organisms are rapidly buried, especially in low-oxygen conditions. Carbonized remains are thin, approximately two-dimensional films of carbon preserved on a flat surface of rock.

What can we learn from trace fossils?

Sometimes, tracks and fossils do tell us something about the organism, for example, dinosaur footprints. Examining the footprints left behind by dinosaurs give us a hint as to the size of the dinosaur. Most of the time there is a certain proportionality between an organism’s body and its legs (feet.)
