Explanation:

Paleontology is the study of pre - historic life. Fossils are remains or traces of ancient species, often preserved in rock. Mold fossils are formed when the organic material decays leaving an imprint. Cast fossils are the opposite, where sediment fills a mold. Petrified fossils are when an organism turns to stone through permineralization. Carbon films are thin carbon - rich layers of an organism. Trace fossils are signs of an organism's activities like footprints.

Answer:

Paleontology is the study of the life that existed in prehistoric times. Examples of fossils include shells, bones, and imprints made by leaves. Fossils are the remains or traces of ancient species that have been preserved. Fossils are not actual remains of an organism. They are formed from the hard parts or impressions left behind. When sediment fills in the remain of a dead organism and later on the soft parts of the organism do not persist, leaving a hollow imprint in the rock. A cast fossil is the opposite of a mold fossil. A cast makes a 3 - D impression of remain buried in the sediment. Petrified fossils are the remains of an organism that has turned into a mineral, rock, or stone through the process of permineralization. A carbon film, also known as carbonaceous film, is the thin carbon - rich layer of an organism that has been preserved as a fossil. Carbon films are created when the organisms undergo a lot of pressure & leaves a perfect outline. Trace fossils are the traces of previous life forms. These can be the day - to - day activities that are preserved and fossilized. Examples can be footprints, burrows, or even bite marks.
