Mold fossils- an empty space is left when an organism is buried in sedimentary and it decays.Cast fossils- Minerals in rocks fill space left by a decayed organism.(replica)Trace fossils- Markings left by an animal. (footprints, trail, or burrow)Petrified fossils- Minerals penetrate and replace all or part of an organism.Imprint fossils
two charachteristics that all good sources of animal fossils have in common are they occur in fairly large numbers in rock layers and have clearly distinguished charchterisitics
An ideal sequence of rock layers that contains all the known fossils and rock.
