Museum unveils world's largest T-rex skull
Measuring 5 feet across, a T. rex skull found 40 years ago in Montana is the world's largest T. rex skull. The specimen is now on display at the Museum of the Rockies at MSU. (Museum of the Rockies photos by John Little)
The skull measures 5 feet long, making it bigger than the previous record-holder--the T-rex named "Sue" at Chicago's Field Museum, according to Jack Horner, the Museum's curator of paleontology.
Skull fragments from the specimen, known as MOR 008, were found in the Hell Creek Formation near Billings in the late 1960s and collected by Bill McMannis, an MSU geologist. Museum preparator Carrie Ancell began their reconstruction in the late 1980s, and preparator Michael Holland finished the job this year.
A single vertebra is the only other piece of MOR 008 that has been found besides the skull.
"We are going to try and figure out how old the animal was when it died by using histology, the study of the microscopic structure of fossil remains," Horner said. "The specimen contains several characteristics that suggest this individual was mature, and perhaps quite old when it died."
Horner said research on the specimen will continue.
MOR 008 is one of three T-rex skulls in the Museum of the Rockies collection, all of which are on display in the Hall of Horns and Teeth. All of them were found in Montana. The Museum has part of twelve T-rexes, more than any other institution in the world.
The Museum of the Rockies is open from 9 to 5, Monday through Saturday, and 12:30 p.m. to 5 p.m. on Sundays through May 26. Summer hours begin May 27 when the Museum will be open from 8 a.m. to 8 p.m. daily through Labor Day.
