Late Cambrian animals (Time serires) - Wildlife in the Fossil sites

Classified animal and plant picture guide. Clicking the Organism name shows the images, and pointing the Organism name shows the tooltip with three links at the left-top corner.
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.
