These fossils typically appear as a thin, dark film on the rock. A mold fossil, also known as a cast fossil, carries a three-dimensional imprint of an organism. When sediment buries an organism, some of the materials that make up the organism evaporate, or become gases. Carbon Film Fossils: Carbon film fossils form when the levels of heat and pressure that form sedimentary rocks squeeze elements such as hydrogen and oxygen out of remains, leaving behind imprints in the form of thin films of carbon on the rock. Feb 14, 2025 · Fossils are the remains or traces of organisms that lived long ago and have been preserved.
