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.
