Classified animal picture guide. Highlighting the link

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

The followings are largest size of small extinct species. The explanation in brackets is the ages they lived in extinct species, and the habitat in extant 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.
