Highest Resolution Scan of T-Rex Skull

Using Los Alamos National Laboratory’s unique neutron-imaging and high-energy X-ray capabilities, researchers have been able to peer into the fossil skull of a 74 million year old tyrannosauroid dinosaur in the highest resolution scan ever done of a tyrannosaur skull.

The 40-inch skull, found in 1996 in the Bisti/De-Na-Zin Wilderness Area near Farmington, was scanned using a combination of neutron and X-ray CT scans. These methods were able to extract anatomical information not otherwise obtainable. “The CT scans help us figure out how the different species within the T. rex family related to each other and how they evolved,” said Thomas Williamson, Curator of Paleontology at the New Mexico museum.

Team members will present their findings on the fossil, Bistahieversor sealeyi, Aug. 23 at the annual Society of Vertebrate Paleontology meeting in Calgary, Alberta.

This research was funded by Los Alamos National Laboratory capability development funds from the Applied Engineering and Technology division, from National Nuclear Security Administration Science Programs, and through a grant to UNM through the New Mexico Consortium.
