Indohyus is an extinct genus of Artiodactyla (Artiodactyla) mounted on the front of about 48 million years ago, the Indian subcontinent lived. Indohyus is considered to be the link between land mammals and whales . Indohyus was about the size of a raccoon and most closely resembles the African stag pig . The thickened ear bone is the most important feature thatspeaksfor the direct descent of whales from Indohyus , because this feature is only found in whales. A strong thickening of the outer bone layers, the so-called osteosclerosis , also indicates that the animals have already partially lived in the water. This characteristic can also be found in the hippos alive todayand it allows an energy-saving, wading method of locomotion under water.
