Montana's T. rex (also known as "Peck's rex", "Peckrex", "Rigby's rex" and Tyrannosaurus "imperator") is the nickname given to a fossil specimen found in Montana in 1997. [54] The discovery was made by Louis E. Tremblay on 4 July 1997 working under the supervision of J. Keith Rigby Jr. who led the excavation and bone preparation.
Modern representations in museums, art, and film show T. rex with its body approximately parallel to the ground with the tail extended behind the body to balance the head. [ 140 ] To sit down, Tyrannosaurus may have settled its weight backwards and rested its weight on a pubic boot, the wide expansion at the end of the pubis in some dinosaurs.

Estimated size compared to a human. Zhuchengtyrannus was a large carnivorous theropod, and the holotype has been estimated to have been "similar in size and gross morphology to Tarbosaurus", [1] which is about 11 metres (36 ft) in body length and 5 metric tons (5.5 short tons) in body mass.
This small temperature range between the body core and the extremities was claimed by paleontologist Reese Barrick and geochemist William Showers to indicate that T. rex maintained a constant internal body temperature (homeothermy) and that it enjoyed a metabolism somewhere between ectothermic reptiles and endothermic mammals.

Victoria is estimated at the age of around 18–25 at the time of her death 65 million years ago. Her skeleton includes approximately 199 bones and nearly complete skull, accounting for about 65% of the total skeleton, making her the second most complete T. rex skeleton discovered to date (behind “Sue” for completeness).
