Paratylopus is an extinct genus of terrestrial herbivore in 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

Restoration of Paratylopus (upper right) and other animals from the late Oligocene of Oregon

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.
