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:
- 73.8 kg (160 lb)
- 78.8 kg (170 lb)
- 48.0 kg (110 lb)
- 52.3 kg (120 lb) [3]
Fossil distribution
Fossil distribution is concentrated along the Gulf Coast from Texas to Florida in 11 different sites.
