| 释义 |
The Irdin Manha Formation is a geological formation from the Eocene located in Inner Mongolia, China, a few kilometres south of the Mongolian border ({{Coord|43.7|112.0|display=inline}}, paleocoordinates {{Coord|45.2|105.7|display=inline}}).[1] U.S. paleontologists Henry Fairfield Osborn and Roy C. Andrews discovered two premolars on the site in 1923, and {{Harvnb|Osborn|1924}} assigned the specimen to the new genus Eudinoceras because he believed it to be related to "Dinoceras" (now known as Uintatherium). Within a decade, however, as more complete specimens were recovered, the animal was identified as a Mongolian relative to the North American pantodont Coryphodon.[2] See also
