[108] Talking about the paper's benefits, Carr explained how all Nanotyrannus specimens fashioned a continual growth transition concerning the smallest juveniles as well as subadults, compared with what might be predicted if it had been a definite taxon where by the specimens would group towards the exclusion of Tyrannosaurus. Carr concluded that "the 'nanomorphs' are not all of that comparable to one another and instead type a vital bridge in the growth series of T. rex that captures the beginnings from the profound modify with the shallow cranium of juveniles on the deep skull that is viewed in fully-made Older people."[109]
Paul turned down the objections raised by critics, insisting that they are unwilling to consider that Tyrannosaurus might stand for multiple species.[83] Inside of a subsequent paper awaiting publication, Paul preserved the conclusion that Tyrannosaurus is made of 3 species. He identified that the criticism of your analyze naming T. imperator and T. regina only focused on two from the functions utilised to differentiate The 2 new species (the volume of tiny incisiform enamel and femur robustness), when the original study also in comparison the robustness of other bones as well (the maxilla, dentary, humerus, ilium and metatarsals).

Precisely, the paper's T. rex was distinguished by strong anatomy, a reasonable ratio of femur size vs circumference, and the possession of a singular slender incisiform dentary tooth; T. imperator was looked upon as robust KS Quik with a little femur size to circumference ratio and two in the slender teeth; and T. regina was a gracile kind by using a substantial femur ratio and among the list of slender tooth. It was noticed that variation in proportions and robustness became additional Severe larger up in the sample, stratigraphically. This was interpreted as an individual before inhabitants, T. imperator, speciating into more than one taxon, T. rex and T. regina.[78]

A 2009 examine confirmed that smooth-edged holes inside the skulls of various specimens might need been due to Trichomonas-like parasites that commonly infect birds. In accordance with the review, critically contaminated folks, including "Sue" and MOR 980 ("Peck's Rex"), may possibly for that reason have died from starvation soon after feeding became increasingly complicated. Beforehand, these holes had been defined through the bacterious bone infection Actinomycosis or by intraspecific attacks.[233] A subsequent analyze identified that though trichomoniasis has lots of characteristics from the design proposed (osteolytic, intra oral) numerous options make the idea that it had been the cause of death fewer supportable by proof. By way of example, the noticed sharp margins with small reactive bone proven through the radiographs of Trichomonas-contaminated birds are dissimilar for the reactive bone noticed while in the afflicted T.

The vertebral column of Tyrannosaurus consisted of ten neck vertebrae, 13 back vertebrae and 5 sacral vertebrae. The amount of tail vertebrae is unknown and will well have assorted in between individuals but almost certainly numbered a minimum of forty. Sue was mounted with forty-7 of this kind of caudal vertebrae.[50] The neck of T. rex shaped a natural S-formed curve like that of other theropods. In comparison to these, it was extremely quick, deep and muscular to assistance the massive head. The 2nd vertebra, the axis, was especially short. The remaining neck vertebrae had been weakly opisthocoelous, i.e. using a convex front of the vertebral physique plus a concave rear. The vertebral bodies experienced solitary pleurocoels, pneumatic depressions made by air sacs, on their own sides.[50] The vertebral bodies in the torso had been strong but which has a slender midsection.
