Overview
- The research, led by the University of Alberta with the Museum of the Rockies, was published this week in PeerJ.
- CT scans conducted at Bozeman Health Deaconess Hospital and comparative morphology linked the embedded tooth to Tyrannosaurus.
- The wound shows no healing, leaving open whether the Edmontosaurus died from the bite or was scavenged shortly after death.
- The tooth’s position in the nose and its breakage indicate a forceful, face-to-face interaction consistent with predation or postmortem feeding.
- The nearly complete skull was discovered in 2005 in Montana’s Hell Creek Formation on BLM-managed land and is now on display at the Museum of the Rockies.
