Abstract
A right metacarpal III represents the first North American record of the giant anteater ( Myrmecophaga tridactyla ). Recovered in northwestern Sonora, Mexico, with a rich vertebrate fauna of early Pleistocene (Irvingtonian) age, it belongs to a cohort of large mammals that dispersed from South America to North America along a savanna corridor. Presumably habitat and climatic changes have subsequently driven this mammalian family more than 3000 kilometers back into Central America from its former expansion into temperate North America.This publication has 6 references indexed in Scilit:
