Eudinoceras fossil map
Where fossils of Eudinoceras have been found, shown on the Earth as it looked about 45 million years ago and on today’s map.
Dots are fossil collections recorded in the Paleobiology Database. The “then” view moves today’s fossil sites back to their positions 45 million years ago (the time slice nearest the median age of the fossils) using the Merdith et al.

About Eudinoceras
Eudinoceras is an extinct genus of pantodont in the family Coryphodontidae. The first fossils were discovered in the Irdin Manha Formation by palaeontologists Henry Fairfield Osborn and Roy Chapman Andrews in 1923, and were assigned to the genus Eudinoceras, due to both thinking it was a dinoceratan closely related to Dinoceras (now known as Uintatherium). As more complete specimens were recovered, the animal was identified as a pantodont more related to the genus Coryphodon.
Eudinoceras was described from 2 premolars & jaw elements. However, more teeth and fragmentary skull material have been found throught Mongolia and China.
