The late Cambrian in Paleozoic spanned from
496 to
488 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.
