Pseudolabis 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

Pseudolabis was named by Matthew (1904). It was assigned to Camelidae by Matthew (1904) 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:

  • 105.3 kg (230 lb)
  • 84.4 kg (190 lb)
  • 77.9 kg (170 lb)
  • 54.3 kg (120 lb) [3]

Fossil distribution

Fossil distribution is restricted to two sites in Wyoming and Nebraska.
