They ended up pneumatized. They ended up linked to the pelvis by transverse processes and sacral ribs. The tail was large and moderately long, as a way to equilibrium The large head and torso and to offer Area for massive locomotor muscles that hooked up to your thighbones. The thirteenth tail vertebra formed the changeover place between the deep tail base and the middle tail which was stiffened by a rather extensive entrance articulation procedures.

[ninety three] Speaking about the paper's results, Carr explained how all "Nanotyrannus" specimens fashioned a continual advancement transition involving the smallest juveniles along with the subadults, not like what could well be envisioned if it were a distinct taxon exactly where the specimens would group for the exclusion of Tyrannosaurus. Carr concluded that "the 'nanomorphs' will not be all of that very similar to one another and in its place variety an essential bridge in the growth series of T. rex that captures the beginnings in the profound modify through the shallow skull of juveniles for the deep skull that's observed in completely-created adults."[ninety four] Paleobiology
Proof also strongly indicates that tyrannosaurs have been at the least at times cannibalistic. Tyrannosaurus by itself has sturdy evidence pointing towards it having been cannibalistic in not less than a scavenging ability based upon tooth marks about the foot bones, humerus, and metatarsals of one specimen.[209] Fossils from the Fruitland Development, Kirtland Development (both equally Campanian in age) and the Maastrichtian aged Ojo Alamo Development recommend that cannibalism was present in many tyrannosaurid genera with the San Juan Basin. The evidence collected in the specimens indicates opportunistic feeding actions in tyrannosaurids that cannibalized associates of their unique species.[210] A examine from Currie, Horner, Erickson and Longrich in 2010 continues to be put forward as evidence of cannibalism while in the genus Tyrannosaurus.
