Description

fossil tooth of an ancient camel, cm 2.2 x 2.1 x 2.4.

Camelids appeared about 45 million years ago during the middle of 'Eocene in North America. The Protylopus was the size of a rabbit, yet with four fingers on each foot. By the end of Eocene, about 35 million years ago, camelids, such as Poebrotherium, lost two fingers side, and were about the size of a modern goat.
The family diversified, but remained confined to the North American continent up to 2-3 million years ago, when representatives arrived in Asia and, after the formation of dell'istmo Panama, in South America.
Three groups of species have survived to today: the dromedary of northern Africa and southeast Asia, the camel of Central Asia and the group of South America, diversified in a series of closely related forms, classified as four species: the llama, alpaca, guanaco and vicuna.
Among the fossil camelids remembers an American genus, the Titanotylopus, 3.5 meters high at the shoulder (compared to about two meters of the largest current Camelidae). Other extinct forms had smaller the size of a gazelle, as Stenomylus. Finally, there is a variety very tall, giraffe-camels, adapted for feeding on the leaves of high trees as Aepycamelus and Oxydactylus.
