Hemiauchenia[1] is a genus of laminoid camelids that evolved in North America in the Miocene period about 10 million years ago. This genus diversified and expanded into to South America in the Late Pliocene approximately 3 to 2 million years ago, as part of the Great American Biotic Interchange. The genus became extinct at the end of the Pleistocene. The monophyly of the genus has been considered questionable, with phylogenetic analyses finding the genus to paraphyletic or polyphyletic, with some species suggested to be more closely related to living lamines than to other Hemiaucenia species.[2][3]
