Description
Another Tyrannosaurus rex adult specimen, and the last one I'm going to make for a really long time (if not ever),since the rest are extremely poorly reported in the literature (so don't ask for more specimens, I beg you!)

AMNH 5027 is the archetypical Tyrannosaurus, as the looks of the animal (including the head the torso and the tail) have been based on this specimen for almost a century,until other specimens have been found and reconstructed, or described. Every media portrayal of the dinosaur, like King Kong, or Jurassic Park, are mainly based on this specimen. The malformation in the back at dorsal7/8 has made it so most representations of the animal are humpy, something that seems to be a characteristic of this single specimen (it has been mostly corrected for this restoration, which also made the torso change in shape and size a bit; the measurement of the cervical and dorsal column length changes from 314,4 cm as referenced in Brown 1923 to 327,9 cm).

The big uncertainly on the size of the tail has led to much debate and different interpretations, the original reconstruction of the animal as ilustrated in Osborn 1917 was 13.4 m long, with the missing caudals restored very big, and with 53 of them. In 1988, Paul proposed the tail length of the mount was inmensely exaggerated and reconstructed the missing elements after a juvenile Gorgosaurus, arriving to 37 caudals and re arranging the positions of the known caudals,which yielded a length of 10.7 m with a tail less than half of the body length, which is like the animal is portrayed on films like Jurassic park, giving it a very compact look. Now the finding of more complete specimens like FMNH PR 2081 and BHI 3033 allow us to know that it is imposible that Tyrannosaurus had only 37 caudals and allow us to arrange the few posterior caudals and restore the size of the missing portions correctly, arriving to something in the middle of what the original reconstruction and Paul suggested (almost 12 m in length).

The specimen is exhibited at the saurischian hall in the American Museum of Natural history. It was originally posed in a raised posture reaching 5.35 m tall to the head, dragging it's tail, and with three functional fingers on each hand. The 5-6 m height figures for Tyrannosaurus are based on the skeletons posed in this manner, as in a regular posture it is not posible for the animal to reach this height. Posterior fidings have confirmed the animal only had two functional fingers and not three, althouth it did have a vestigial metacarpal lll. The specimen as mounted still has the exaggerated tail, and is therefore still the longest carnivorous dinosaur mount that includes real remains in the world, even if it is not the largest specimen when one compares the preserved material with the corresponding of the others. The legs in the mounted skeleton are casts of the holotype specimen, and the feet and hands are completely sculpted and not directly based on any Tyrannosaurus rex specimen because they were still unknown when the mount was updated; in fact, the feet are scaled up Allosaurus feet.
