T. rex was one of the largest land carnivores of all time. One of the largest and the most complete specimens, nicknamed Sue (FMNH PR2081), is located at the Field Museum of Natural History in Chicago.
Sue measured 40.4 to 40.7 ft. long, was 12 to13 ft. tall at the hips, and according to the most recent studies, using a variety of techniques, maximum body masses have been estimated approximately 9.26 to 9.33 short tons.
A specimen nicknamed Scotty (RSM P2523.8), located at the Royal Saskatchewan Museum, is reported to measure 43 ft. in length. Using a mass estimation technique that extrapolates from the circumference of the femur, Scotty was estimated as the largest known specimen at 9.78 short tons in body mass.
Not every adult Tyrannosaurus specimen recovered is as big. Historically average adult mass estimates have varied widely over the years, from as low as 5.0 short tons, to more than 7.9 short tons, with most modern estimates ranging between 6.0 short tons and 8.8 short tons.
The largest known T. rex skulls measure up to 5 ft. in length. Large openings in the skull reduced weight, as in all carnivorous theropods. In other respects Tyrannosaurus’s skull was significantly different from those of large non-tyrannosaurid theropods. It was extremely wide at the rear but had a narrow snout, allowing unusually good binocular vision.
The skull bones of Tyrannosaurus Rex were massive and the nasals and some other bones were fused, preventing movement between them; but many were pneumatized (contained a “honeycomb” of tiny air spaces) and thus lighter.
The tip of the upper jaw was U-shaped which increased the amount of tissue and bone a tyrannosaur could rip out with one bite, although it also increased the stresses on the front teeth.
The teeth of T. rex displayed marked differences in shape.
The premaxillary teeth, four per side at the front of the upper jaw, were closely packed, D-shaped in cross-section, had reinforcing ridges on the rear surface, were incisiform (their tips were chisel-like blades) and curved backwards. The D-shaped cross-section, reinforcing ridges and backwards curve reduced the risk that the teeth would snap when Tyrannosaurus Rex bit and pulled.
The lower jaw was robust. Its front dentary bone bore thirteen teeth. Behind the tooth row, the lower jaw became notably taller.
The upper and lower jaws of Tyrannosaurus Rex possessed small holes in the bone. Various functions have been proposed for these foramina, such as a crocodile-like sensory system or evidence of extra-oral structures such as scales or potentially lips, with subsequent research on theropod tooth wear patterns supporting such a proposition
The remaining teeth were robust rather than daggers, more widely spaced and also had reinforcing ridges. Those in the upper jaw, twelve per side in mature individuals, were larger than their counterparts of the lower jaw, except at the rear.
The largest tooth found so far is estimated to have been 12 in. long including the root when the animal was alive, making it the largest tooth of any carnivorous dinosaur yet found.
