• Trace Fossil

• Cast Fossil

• Mold Fossil

A woolly mammoth or ancient hominid might be found in frozen tundra such as the arctic circle. This type of fossil would be

• preserved or original remains

• permineralized or petrified

• carbonized or carbon film

• trace

This type of fossil is formed from dung or waste materials and allows scientists to infer the feeding habits of ancient animals.

• gastroliths

• coprolites

• halites

• chemo-synthesis

These fossils are distinguishable from other fossils because they were scattered over a large region, very common, and lived during a short span of geologic time. They also help geologists date a particular layer of rock or other fossils found in a similar layer.

• trace

• index

• permineralized

• mold and cast
