Miotylopus is an extinct genus of terrestrial herbivore in the family Camelidae, endemic to North America from the Late Oligocene through Early Miocene 24.8—20.6 mya, existing for approximately 4.2 million years.[1]

Taxonomy[edit]

Miotylopus was named by Schlaikjer (1935). It is not extant. Its type is Miotylopus bathygnathus. It was assigned to Camelidae by Schlaikjer (1935) and Carroll (1988).[2]

Morphology[edit]

Four specimens were examined for estimated body mass by M. Mendoza, C. M. Janis, and P. Palmqvist. These specimens were estimated to weigh:

  • 77.0 kg (170 lb)
  • 75.6 kg (170 lb)
  • 59.7 kg (130 lb)
  • 53.8 kg (120 lb) [3]

Fossil distribution[edit]

Fossil distribution is restricted to Wyoming and Nebraska to Southern California.
