Afrotheria Past and Present - Animals in the Habitats and the Fossil sites, and Biodiversity
The followings are extinct Afrotheria excavated and extant Afrotheria in the world. 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.
