Priscocamelus is an extinct genus of terrestrial herbivore in 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]

Taxonomy

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.
