Scientists with the Tate Geological Museum at Casper College last year uncovered approximately 120 bones from a mammoth estimated to be up to 2 million years at a site outside of Douglas.
Museum Director Dave Brown said several important bones have yet to be found, including the skull, tusk, lower jaw and several leg bones. The mammoth site us under 24-hour guard and is on private land.
"We found a good part of (the skeleton) last year," Brown said. "The primary thing we are looking for now is the skull and the tusk."
Workers last year found a portion of one tusk measuring 4 feet long and 9 inches in diameter, Brown said.
"At this point there have been no human remains found," Brown said. "So this one probably wandered down into a gully and died."
The mammoth is called "Dee," in honor of bulldozer operator Dee Zimmerschied, who discovered the first bones while bulldozing an oil well drilling site in 2006.
Brown said the mammoth was about 14 feet high at the shoulder and about 40 years old when it died. He said it may be one of the most complete and largest mammoth skeletons ever discovered in Wyoming.
Brown said the plan is to display the skeleton at the museum when it's restored.
