The Early Permian in Paleozoic spanned from
299 to
270 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 italic and bold figures, e.g.
488, show out of the range. The time range is shown in the
Geological Time Table. The followings are a part of the Evolutionary Tree.
