Paratylopus is an extinct genus of terrestrial herbivore the family Camelidae, endemic to North America from the Eocene through Oligocene 38.0—30.8, existing for approximately 7.2 million years.[1] It belongs to mammal class.
Taxonomy
Paratylopus was named by Matthew (1909) [named as subgenus by Matthew 1904; raised to genus level]. It was assigned to Camelidae by Matthew (1909) and Carroll (1988).[2][3]
Morphology
Four specimens were examined for estimated body mass by M. Mendoza, C. M. Janis, and P. Palmqvist. These specimens were estimated to weigh:
- 52.2 kg (120 lb)
- 44.8 kg (99 lb)
- 38.5 kg (85 lb)
- 42.9 kg (95 lb) [4]
Fossil distribution
Fossil distribution is centered in western Wyoming, eastern Nebraska to northeastern Colorado to southwestern South Dakota.
