Over earth’s history, there have been many different types of animal life. We know this because of fossils that have been found in many parts of the world. Amphibians, reptiles, and mammals have dominated the earth at different times.
Animals Past and Present takes a look at what types of animals were present during different time periods. It also explains how such things as plate tectonics, climate, and other factors affected these animals and the ecosystems they lived in.
