What is a Coryphodon related to?
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, replacing Barylambda, an earlier pantodont. It is regarded as the ancestor of the genus Hypercoryphodon of Late Eocene Mongolia.
Where was the Coryphodon found?
The pantodont Coryphodon is a frequently found component of early Eocene terrestrial faunas in North America, distributed widely from the Arctic to the Gulf Coast.
When did Coryphodon go extinct?
to 52 million years ago
Coryphodon, genus of extinct primitive hoofed mammals known from Late Paleocene and Early Eocene deposits (those that date from about 63.5 to 52 million years ago) in North America and Early Eocene deposits in Europe and eastern Asia (the Paleocene epoch, which preceded the Eocene epoch, ended about 54,000,000 years …
What is the meaning of Coryphodon?
Coryphodon (meaning peaked tooth) is an extinct genus of mammal. It was widespread in North America between 59 and 51 million years ago. It is regarded as the ancestor of the genus Hypercoryphodon of Mid Eocene Mongolia. Coryphodon was a pantodont, a member of the world’s first group of large browsing mammals.
Is there a sexual dimorphism in Coryphodon teeth?
Uhen & Gingerich 1995 noticed a sexual dimorphism in Coryphodon: the canines tend to be either very large or very small compared to cheek teeth, and, comparing to modern hippos, there is reason to assume males had larger canines than females. Owen, Richard (1845). Odontography; a treatise on the comparative anatomy of the teeth.
What did Coryphodon eat in the winter?
Chemical studies of fossil bone show that in the summer, Coryphodon ate flowers, leaves, and swamp plants. In the winter dark, they survived on pine needles, dead leaves, and fungi. This flexible diet allowed the species to spread widely across the Eocene world.
What is the average body weight of a Corydoras eocaenus?
Based on a regression analysis of ungulates, Uhen & Gingerich 1995 estimated the mean body mass for the type species C. eocaenus to 340 kg (750 lb), 600 kg (1,300 lb) for C. radians, and possibly as much as 700 kg (1,500 lb) for C. proterus and C. lobatus.
