Mold and Cast Formation of Fossils

The video explains how fossils are formed when plants or animals are buried by sediments. Two types of fossils, molds and casts, are discussed. Molds are spaces left after the organism decays, while casts form when these spaces are filled with minerals or sediments. The video highlights the significance of casts in paleontology, as they preserve the shape and features of ancient organisms.
