What is "hemiauchenia"

Hemiauchenia is a genus of lamine camelids that evolved in North America in the Miocene period approximately 10 million years ago. This genus diversified and moved to South America in the early Pleistocene as part of the Great American Interchange, giving rise to modern lamines. The genus became extinct at the end of the Pleistocene.

Remains of these species have been found in assorted locations around North America including: Florida, Texas, Kansas, Nebraska, Arizona, Mexico, California, Oklahoma, New Mexico, Colorado and Washington. The "large-headed llama", H. macrocephala, was widely distributed in N. and Central America, with H. vera being known from the western U. S. and northern Mexico. H. minima has been found in Florida, and H. guanajuatensis in Mexico.
