Priscocamelus is an extinct genus of terrestrial herbivore the family Camelidae, endemic to North America from the Oligocene through Miocene 24.8—20.6 mya, existing for approximately 4.2 million years.[1]

Priscocamelus was named by Stevens (1969) [in Stevens et al.]. Its type is Priscocamelus wilsoni. It was assigned to Camelidae by Stevens (1969) and Carroll (1988).[2]
Morphology
Body mass
Four specimens were examined for estimated body mass by M. Mendoza, C. M. Janis, and P. Palmqvist. These specimens were estimated to weigh:
- 106.3 kg (230 lb)
- 98.3 kg (220 lb)
- 91.4 kg (200 lb)
- 72.3 kg (160 lb) [3]
Fossil distribution
Fossil distribution is restricted to two sites in the Rio Grande valley of Texas.
