Classified animal 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 Ordovician 2st era in Paleozoic spanned from 488 to 443 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.
