Extinction Paleontology Earth Sciences
Extinction Paleontology Earth Sciences
Most animals and plants that ever lived died out long before the present. The fossil record reveals that there are several periods of time in the earth's past when the extinction rate was very high (e.g., at the Cretaceous/Tertiary boundary, and the Permian/Triassic boundary) - causing mass extinctions of a large percentage of the species.
This category contains sites dealing with the subjects of extinction and mass extinctions in the fossil record.
