Species
  • P. cedrensis

Paralabis is an extinct genus of terrestrial herbivore the family Camelidae, endemic to North America from the Oligocene 33.3—30.8 mya, existing for approximately 2.5 million years.[1]

Taxonomy

Paralabis was named by McKenna (1966) [named as subgenus by Lull 1921; raised to genus level]. It was assigned to Camelidae by McKenna (1966) and Honey et al. (1998).[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:

  • 92 kg (200 lb)
  • 49.7 kg (110 lb)
  • 37 kg (82 lb)
  • 33.8 kg (75 lb) [3]

Fossil distribution

Fossil distribution is restricted to Wyoming and eastern Nebraska.
