Giant Mammoth Skull Discovered by Bulldozer Operator

A bulldozer operator at a sand pit in northwestern Oklahoma got quite a surprise this month when he spotted a huge skull that belonged to a Columbian mammoth. These giants were plentiful across the plains of Oklahoma during the Pleistocene epoch, which lasted from about 1.8 million to 11,700 years ago, said Leland Bement of the Oklahoma Archaeological Survey. The discovery was not unheard of, as the Survey typically receives about three "mammoth-sighting" calls a year, Bement said.
