Coryphodon fossil map
Where fossils of Coryphodon have been found, shown on the Earth as it looked about 56 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 56 million years ago (the time slice nearest the median age of the fossils) using the Merdith et al. (2021) plate model; positions are approximate. Open on the timeline map →

About Coryphodon
Coryphodon (from Greek κορῦφὴ, "point", and ὀδοὺς, "tooth", meaning peaked tooth, referring to "the development of the angles of the ridges into points [on the molars].") is an extinct genus of pantodonts of the family Coryphodontidae.
Coryphodon was a pantodont, a member of the world's first group of large browsing mammals. It migrated across what is now northern North America (being among the largest of fauna in Wasatch Formation), replacing Barylambda, an earlier pantodont. It is regarded as the ancestor of the genus Hypercoryphodon of Late Eocene Mongolia.
Coryphodon is known from many specimens in North America and considerably fewer in Europe, Mongolia, and China. It is a small to medium-sized coryphodontid which differs from other members of the family in dental characteristics.
