of species shows the images, and clicking the link shows Evolutionary Tree.The following fossils from the geologic age to the prehistorical age are excavated in Antarctica. 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.
