Bite-force estimation for Tyrannosaurus rex from tooth-marked bones
Article Abstract:
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.

101 uses for fossilized faeces
Article Abstract:
Fossilized faeces, or coprolites, can give an indication of the diet of long-dead animals and the environment in which they lived. The similarity of coprolites means that it is essential that they can be linked to animal species if information obtained is to be useful. Until now, few coprolites have been positively linked to carnivorous dinosaurs. A new study describes a coprolite from Canada that may be the first known coprolite from Tyrannosaurus rex.

A king-sized theropod coprolite
Article Abstract:
Coprolites, or fossil faeces, can provide valuable information about the diet and environment of long-dead animals. Many coprolites have been found but it has been impossible to attribute any specimens to carnivorous dinosaurs. The size, composition and location of a large coprolite found in Canada suggest that it is the first known coprolite from Tyrannosaurus rex.
