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.

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.

Abstract

Paleontologists discovered a Tyrannosaurus rex bone, which contains what looks like the original structure of blood vessels and other soft tissues. This astonishing finding has fueled discussion on whether DNA fragments or proteins may have survived intact during their 70-million-year entombment, which could give detailed information of the animal's metabolism, and the possible answer to the warm-blooded/cold-blooded debate.

44. Dynamics-based analysis of the anti-gravity functions of hindlimb muscles in Tyrannosaurus and other bipeds

Abstract

We constructed three-dimensional musculoskeletal computer models to assess the capacities (per unit muscle force) of all major hindlimb muscles to generate vertical ground-reaction forces (GRF) at the foot, and thus support the body. To cover a broad size range and evolutionary spectrum, we modeled Tyrannosaurus, Gallus, and Struthio, among other bipeds. Musculoskeletal geometry was derived from phylogenetically-constrained published reconstructions or from dissection. Analysis of our models showed how limb orientation influences support provided by the skeleton rather than by muscles. For Tyrannosaurus, joint contact forces support ~25% of body weight (BW) in a straight-legged pose, versus only ~4% BW in more crouched poses. Thus a crouched pose dramatically increases the support that must be provided by muscles. In the Tyrannosaurus crouched pose, when muscles act in isolation, ankle and toe muscles provide much more vertical GRF (e.g., M. flexor digitorum longus: 1.2 N vertical GRF/1 N muscle force) than knee extensors (e.g., M. femorotibialis externus: 0.27 N/1 N), which in turn are more effective than hip extensors (e.g., M. caudofemoralis longus: 0.14 N/1N). These results demonstrate that more distal muscles are more effective in generating vertical GRF than proximal muscles when the muscles act in isolation. However, proximal muscles are very effective in generating vertical GRF when they are activated synergistically with ankle extensors and toe flexors, which stiffen the distal joints and help transfer energy from proximal muscles to the ground. Our simulations show that these general principles hold not only for Tyrannosaurus, but also for chickens, ostriches, and other bipeds, including humans.

Abstract

Scientists are confident that a sample of fossil faeces found within two kilometers of an excavated Tyrannosaurus rex will reveal the dinosaur's eating habits. The scientists have spent three years analysing the specimen after spotting bone fragments within the faeces and they reported in the June 18 issue of 'Nature' that the sample had to come from a Tyrannosaurus because of its large size. They also deduced that the creature crushed its meal before ingesting it. Previously, scientists did not think that theropods crushed bones prior to eating them.
