of species shows the images, and clicking a link shows Evolutionary Tree.

The early Cambrian in Paleozoic spanned from 542 to 513 millon years ago. The explanation in brackets is the ages they lived in extinct species. Note that Mya is million years ago. For example, "48.6～40.4 Mya" shows a range between 48.6 and 40.4 million years ago. The time range is shown in the Geological Time Table. The followings are a part of the Evolutionary Tree.
