Possible footprint from New Mexico Two isolated fossilized footprints happen to be tentatively assigned to T. rex. The primary was uncovered at Philmont Scout Ranch, New Mexico, in 1983 by American geologist Charles Pillmore. Initially imagined to belong to a hadrosaurid, evaluation from the footprint uncovered a significant 'heel' unidentified in ornithopod dinosaur tracks, and traces of what may possibly are a hallux, the dewclaw-like fourth digit with the tyrannosaur foot.

Within the 1910s with the conclude of your 1950s, Barnum's discoveries remained the only specimens of Tyrannosaurus, as the Great Depression and wars held numerous paleontologists away from the sphere.[5] Resurgent fascination
Only only one Tyrannosaurus specimen is conclusively demonstrated to belong to a specific sex. Evaluation of B-rex shown the preservation of soppy tissue in a number of bones. Several of this tissue has long been identified to be a medullary tissue, a specialised tissue grown only in fashionable birds as being a supply of calcium with the production of eggshell in the course of ovulation. As only woman birds lay eggs, medullary tissue is just identified Obviously in women, Even though males are able of manufacturing it when injected with woman reproductive hormones like estrogen.
The damage to the tail vertebrae of the Edmontosaurus annectens skeleton (on Display screen in the Denver Museum of Character and Science) suggests that it may well are actually bitten by a Tyrannosaurus A skeleton with the hadrosaurid Edmontosaurus annectens has been described from Montana with healed tyrannosaur-inflicted hurt on its tail vertebrae. The reality that the injury appears to have healed indicates the Edmontosaurus survived a tyrannosaur's attack on the living focus on, i.e. the tyrannosaur had tried Lively predation.[214] Regardless of the consensus which the tail bites had been brought on by Tyrannosaurus, KS Quik there has been some proof to indicate that they could happen to be designed by other components. By way of example, a 2014 analyze suggested the tail accidents might need been because of Edmontosaurus people today stepping on each other,[215] whilst A different research in 2020 backs up the speculation that biomechanical tension may be the trigger for the tail injuries.[216] There is certainly also proof for an intense conversation involving a Triceratops as well as a Tyrannosaurus in the shape of partly healed tyrannosaur tooth marks with a Triceratops brow horn and squamosal (a bone of your neck frill); the bitten horn is additionally damaged, with new bone advancement following the crack.
Many phylogenetic analyses have discovered Tarbosaurus bataar to generally be the sister taxon of T. rex.[sixty] The invention of the tyrannosaurid Lythronax more signifies that Tarbosaurus and Tyrannosaurus are carefully connected, forming a clade with fellow Asian tyrannosaurid Zhuchengtyrannus, with Lythronax currently being their sister taxon.

O'Connor, a curator at the sphere Museum, exactly where the T. imperator holotype Sue is shown, regarded the new species as as well inadequately-supported to justify modifying the exhibit indicators. Brusatte, Carr, and O'Connor considered the distinguishing options proposed involving the species as reflecting all-natural variation within a species. Both Carr and O'Connor expressed fears regarding the study's inability to pick which in the proposed species several perfectly-preserved specimens belonged to. One more paleontologist, Philip J. Currie, at first co-authored the examine but withdrew from it as he didn't want to be involved with naming the new species.[79]
