During the Miocene period, approximately 10 million years ago, the genus Hemiauchenia - lamine camelids - evolved in North America. As part of the Great American Biotic Interchange, this genus diversified and moved to South America in the Early Pleistocene, giving rise there to modern lamines. The genus became extinct at the end of the Pleistocene. This is a perfect preserved tooth of Hemiauchenia macrocephala, with just a small damage in the root section.
