In scientific studies described in Science in April 2007, Asara and colleagues concluded that 7 traces of collagen proteins detected in purified T. rex bone most closely match Individuals documented in chickens, accompanied by frogs and newts. The invention of proteins from the creature tens of many many years outdated, in conjunction with similar traces the crew present in a mastodon bone at the least one hundred sixty,000 decades old, upends the conventional check out of fossils and should shift paleontologists' emphasis from bone searching to biochemistry.
As outlined by Currie gregariousness in Albertosaurus sarcophagus is supported by the invention of 26 persons with different ages in the Dry Island bonebed. He ruled out the potential for a predator trap a result of the comparable preservation condition of people as well as the near absence of herbivores.[192][193]
Probable footprint from New Mexico Two isolated fossilized footprints have already been tentatively assigned to T. rex. The initial was found at Philmont Scout Ranch, New Mexico, in 1983 by American geologist Charles Pillmore. At first assumed to belong to your hadrosaurid, evaluation from the footprint exposed a large 'heel' not known in ornithopod dinosaur tracks, and traces of what may well are already a hallux, the dewclaw-like fourth digit from the tyrannosaur foot.

[224] They researched some Tyrannosaurus specimens with tooth marks inside the bones, attributable to the identical genus. The tooth marks have been recognized within the humerus, foot bones and metatarsals, and this was viewed as proof for opportunistic scavenging, rather than wounds brought on by intraspecific battle. In a very fight, they proposed It will be difficult to attain right down to bite in the ft of a rival, making it far more most likely the bitemarks had been built in a carcass. Given that the bitemarks were produced in overall body parts with relatively scantly amounts of flesh, it really is instructed that the Tyrannosaurus was feeding on the cadaver by which the greater fleshy areas by now had been consumed. They had been also open up to the likelihood that other tyrannosaurids practiced cannibalism.[224] Parenting
Mounted skeletons of different age groups (skeleton in lower still left based upon the juvenile previously named Stygivenator), Normal Record Museum of La County Philip J. Currie recommended that Tyrannosaurus could have already been pack hunters, evaluating T. rex to linked species Tarbosaurus bataar and Albertosaurus sarcophagus, citing fossil evidence that will show gregarious (describing animals that vacation in herds or packs) behavior.

Evidence also strongly suggests that tyrannosaurs were a minimum of from time to time cannibalistic. Tyrannosaurus itself has powerful evidence pointing to it acquiring been cannibalistic in a minimum of a scavenging ability according to tooth marks within the foot bones, humerus, and metatarsals of one specimen.[224] Fossils with the Fruitland Development, Kirtland Development (each Campanian in age) along with the Maastrichtian aged Ojo Alamo Formation propose that cannibalism was present in different tyrannosaurid genera in the San Juan Basin. The evidence gathered in the specimens suggests opportunistic feeding behavior in tyrannosaurids that cannibalized members of their very own species.[225] A study from Currie, Horner, Erickson and Longrich in 2010 continues to be put ahead as evidence of cannibalism inside the genus Tyrannosaurus.
