Bite-force estimation for Tyrannosaurus rex from tooth-marked bones

The teeth of Tyrannosaurus rex were strong and impact-resistant, indicating that their tolerance to stresses associated with prey capture were strong. An analysis of fossils containing T. rex bite marks shows that the dinosaurs could generate huge bite forces. These characteristics facilitated their utilization of scavenged carcasses. The teeth could tolerate heavy compression and bending forces. Tooth mark evidence indicate that T. rex could sustain large bite forces and repetitive bone impacts.
