BLOG: Could Cloning Tech Resurrect the Mammoth?
The hybridization of mammoths may explain other fossils that look like intermediates between the two species. These fossils were sometimes assigned to the species Mammathus jeffersonii, but further research may show them to be hybrids of the woolly and Columbian mammoths.
The woolly mammoth was a smaller furrier beast, that lived in the north closer to the glaciers of the Ice Ages, from Alaska through Canada, and east to the Great Lakes and New England. The larger Columbian mammoth lived further south. It inhabited the western and southern portion of the U.S. as far south as Florida, and nearly to Chiapas in Mexico.
The mammoths should not be confused with the American mastodon (Mammut americanum), another ancient elephant from North and Central America.
