[1] This is contrasted with grazing , usually associated with animals feeding on grass or other lower vegetations.
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 .
These two groups now comprise 36% and 60%, respectively, of all South American rodent species. The corresponding figures are 10% and 27% for Central America, 2% and 10% for Mexico, 0.5% and 3% for North America north of Mexico, and 72% and 27% for recent endemic Caribbean rodents.

Ancestral sigmodontine rodents [3] apparently island-hopped from Central America to South America 5 or more million years ago, [4] [5] [6] prior to the formation of the Panamanian land bridge. They went on to diversify explosively, and now comprise 60% of South America's rodent species, while only making up 27% of Central America's. [n 2]
