Paralabis is an extinct genus of terrestrial herbivore in 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.
