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.
