A cast is when that mold has been filled in with rock or minerals. Carbonization-Carbonization is a process in which the more volatile substances of the organism (hydrogen, oxygen, nitrogen, etc) are removed, leaving behind the carbon.These fossils typically appear as a thin, dark film on the rock. This type of preservation is common among plant fossils. cast is when that mold has been filled in with rock or minerals.

Fossils are not only the actual remains of organisms, such as teeth, bones, shell, and leaves (body fossils), but also the results of their activity, such as burrows and foot prints (trace fossils), and organic compounds they produce by biochemical processes (chemical fossils).lant Fossils The fossilization of plants markedly differs from that of animals. The leaves are frequently reduced to a carbon film in a process known as carbonization or distillation.
