Michenia is an extinct genus of terrestrial herbivore in the family Camelidae, endemic to North America from the Oligocene through Pliocene 24.8—4.9 mya, existing for approximately 19.9 million years.[1]
Taxonomy
Michenia was named by Frick and Taylor (1971). Its type is Michenia agatensis. It was assigned to Camelidae by Frick and Taylor (1971) and Carroll (1988).[2][3]
Morphology
Two specimens were examined for estimated body mass by M. Mendoza, C. M. Janis, and P. Palmqvist. These specimens were estimated to weigh:
- 224.9 kg (500 lb)
- 121.9 kg (270 lb) [4]
Fossil distribution
Fossil distribution ranged from California to Texas to Alberta, Canada and to Idaho and Nebraska.
