IMPERIAL MAMMOTH

Imperial Mammoth Fossils For Sale

LATE PLIOCENE TO PLEISTOCENE PERIOD:  4.9 million to 10,000 years ago

Emerging 55 million years ago, the group of mammals called Proboscideans are identified by the presence of tusks and a trunk and include mammoths, mastodons and elephants.  The oldest mammoth remains have placed the beginnings of the beasts in Africa but eventually, they migrated to Europe and Asia.

The Imperial Mammoth (Mammuthus imperator) was a massive Ice Age beast, the largest mammoth that ever lived in North America.  It is a contemporary of the Columbian Mammoth and a descendant of Mammuthus meridionalis, an earlier species that migrated across the Bering Land Bridge into North America around one million years ago.  The Mammoth and the Columbian Mammoth are often confused but a way to remember the difference is that Imperial mammoths had tusks that crossed whereas Columbian mammoths did not.  These mammoths ranged from Alaska to Florida and as far south as Mexico and Central America.  While most think of the Woolly Mammoth to be large, it was not and especially when standing alongside the giant Imperial Mammoth.  The Imperial Mammoth stood almost 16 feet at the shoulder as opposed to the Woolly Mammoth who stood only about 9 feet at the shoulder.  The Imperial Mammoth weighed about 8-10 tons and could consume about 700 pounds of vegetation a day.  The life span for a Imperial Mammoth was 60 to 80 years.  They became extinct 17,000 years ago along with all other Proboscideans in North America.  Associated Paleo-Indian stone tools have been found at some fossil sites indicating these massive beasts were hunted by early North American Indians.  The famous scene of mammoths being attacked by Saber Cats in the La Brea tar pits in California are of the Imperial Mammoth.
