This phenomenon happens because there are predators and other elements that take advantage of the lack of animal life. Examples of such elements can be human based. Other factors that cause extinctions include rapid climate changes and massive asteroid collisions. Some examples of plants also go extinct like the Passenger Pigeon or the Endangered Polar Bear. In order to help you better understand these events, here is a list of some animals that disappeared from Earth.

The first animals to go extinct were forms of mammals. The Dinosaurs became extinct about 65 million years ago, which is the earliest example of extinction. The next animals to disappear were birds. A record number of birds went extinct during the Cretaceous geological period.

A number of amphibians and fishes also became extinct. Amphibians include the Triceratops, Stegosaurus, Pteryx, and Ankylosaurians. They made up a number of genera, including Patagopteryx and Ornithischia. Fishes include the Diogenidae, Squamata, and Ensifera. There are a number of sharks too.
