The oldest known tyrannosaurus is
Proceratosaurus bradleyi, which lived about 167 million years ago and was
roughly the size of a wolf.
Feathers are rarely kept in the
fossil record, so they were not found on a T. Rex specimen. But other dinosaur
fossils, including other tyrannosaur species and their relatives, have retained
feathers. This means paleontologists can "safely assume" that T. Rex
also had feathers, considers Mark Norell.
The T. Rex was like "the
James Dean of dinosaurs," says Gregory Erickson, a Florida State
University paleontologist who was consulted for the museum's exhibit. The
Hollywood actor, often associated with the famous quote "Live fast, die
young and leave a beautiful corpse," died in a car accident at the age of
24. The T. Rex, too, was spectacular but died very young.

Paleontologists can estimate how
old a dinosaur was when it died by analyzing its fossilized bones, which have
growth rings corresponding to its age, much like trees. Experts can count the
number of rings to determine its age, as well as compare the spaces between
those rings to find out how quickly the dinosaur was growing at different ages.
A T. Rex grew from a tiny baby
bird to a 9-tonne predator in 18 to 20 years, gaining around 770 kg per year. The
T. Rex's puny arms were vestigial - a part of the body or organ that no longer
performs a function but is nevertheless preserved (much like a human's appendix
or wisdom teeth).
They admire a life-size model
tyrannosaurus rex with feather spots - the most scientifically accurate
representation of the dinosaur to date by tyrannosaurus
rex skeleton. An adult Tyrannosaurus rex weighed around 6-9 tons. It was
between 3.6 and 4 meters tall (at the hip) and was approximately 12 to 13
meters long. It is referred to as the king of the dinosaurs evolved from a
larger group of tyrannosaurs that were smaller and faster.
While the T. Rex appeared about
68 million years ago, its tyrannosaur ancestors were 100 million years older
than that. The tyrannosauroid super family is made up of two dozen species
spanning more than 100 million years of evolution. You can buy the tyrannosaurus

The ancient tyrannosaurs' arms
were long enough to grab prey or shoot food into their mouths. The earliest
species of tyrannosaurus had perfectly proportioned arms.
The predator had the rare ability
to bite through and digest strong bone. Paleontologists know this thanks to the
fossilized excrement of the dinosaur; they discovered T. Rex faces containing
tiny pieces of bone eroded by stomach acid.
Debates over whether the dinosaur
was a hunter or a scavenger have raged over the years, but "much of the
evidence indicates that tyrannosaurus rex was considered as a predator, not a
scavenger,
The tyrannosaurus rex skeleton
reveals that it was large, carnivorous, and had a small brain, explains Gregory
Erickson. But now paleontologists know that the dinosaur had some of the
largest eyes of all land animals.
The size of an orange, the T.
Rex's eyes were pointed forward like a hawk's and were farther apart in its
face than those of most other dinosaurs, giving it a sense of greater depth
