Titanotylopus - large extinct members of the family Camelidae (Camelidae), lived in North America from the late Miocene to about the mid-Pleistocene (10.3 million - 850 thousand years ago). In the genus is known only species - T. nebraskensis.
The genus name «Titanotylopus» - derived from the Greek words Τιτάν, τύλος and πούς - "Titan", "callus" and "foot". In general, the literal translation sounds like "a giant calloused foot."
Notable examples of these megacamels belonged to animals from 2.5 to about 3 meters in height in the back and weighing up to 2,5 tons. Thus, together with Aepycamelus, Megacamelus and Gigantocamelusit it is a tremendous camels in North America.
Outwardly, they looked like rather strange high on the huge humpback "camel-llamas." Shorter body was formed, probably to save energy. To the high spinous processes of thoracic vertebrae, towering up above the big barrel chest, fastened developed musculature. All of this is probably due to the fact that they had to make long seasonal migrations.
The cause of extinction Titanotylopus, perhaps, were the Pleistocene glaciation, which have resulted in the North American mainland has repeatedly formed a huge ice sheet, which significantly limited the habitat of these camelids. And, accordingly, such climatic "shakeup" could not affect the plant-based food. Also, could play a significant role distribution of mammoths migrated from Asia to North America. These huge green eaters themselves often form the landscape, breaking, eating and trampling the trees, as do African elephants.
