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

Most fossils are found in sedimentary rock and not igneous or metamorphic because

• fossils form at the surface where plants and animals live.

• the processes that create igneous and metamorphic rocks, intense heat and pressure would destroy the fossils.

• animals and plants don't live near volcanoes

A geologist hiking through the woods in Ohio finds rocks containing fossils in a stream bank. The fossils look similar to animals currently living in the ocean. Which conclusion should the geologist make based on the discovery of these fossils?

• Animals that live in the stream today lived in the ocean long ago.

• The area of the woods and stream was an ocean long ago.

• The area with the stream will become part of the ocean in the future.

Even though cast fossils look like the original bone or shell, they are different because they:

• preserve both hard and soft parts of the organism

• are made of rock, minerals, and sediment

• have skin, hair, and feathers
