Nothokemas is an extinct genus of terrestrial herbivore the family Camelidae, endemic to North America from the Oligocene through Miocene 30.8— 20.430 mya, existing for approximately 10.757 million years.[1]

Taxonomy

Nothokemas was named by White (1940) [also said to be 1947]. It was assigned to Camelidae by White (1940) and Honey et al.[2]

Morphology

Four specimens were examined for estimated body mass by M. Mendoza, C. M. Janis, and P. Palmqvist. These specimens were estimated to weigh:

Fossil distribution

Fossil distribution is concentrated along the Gulf Coast from Texas to Florida in 11 different sites.
