It was the year 1902 when the first tyrannosaurus rex skeleton was
discovered. It was founded by the famous palaeontologist Barnum Brown. The king
of the dinosaurs, Tyrannosaurus rex has been named after the Greek word
“tyrant” and “lizard”. The name means Tyrant Lizard king. This species used to
live between 68 and 66 million years ago. This period is denoted as the late
Cretaceous Period. At the end of this period, the asteroid ended the epoch of
dinosaurs.
Body covered with feathers
The fossils of T Rex did not preserve feature on it, but other
skeletons of this tyrannosaurus family had features on them. Hence, it is
assumed by the palaeontologist that T-Rex also had feathers. Especially the
babies do have fur on their entire body. A grown-up T-Rex had little features
on their body all through their life. The hatched, T-Rex looked like feathery Turkish
than that of a predator.
Lifespan
From the tyrannosaurus rex skeleton, researchers found that T. Rex
had a short lifespan. They grew up very fast and could start preying at the age
of four. It is easy to determine the lifespan of a T Rex by analysing the
fossilized body of this species. From the growth rings of bones, it is possible
to calculate the age of the predator. It is also possible to identify how fast
a dinosaur used to grow by analysing the spaces between the rings. From the
analysis, we came to know that the average lifespan of T-Rex was between 28 to
30 years.
Gaining weight
The palaeontologist also discovered that a hatchling T Rex used to
gain weight almost 1700 pounds per year. The transformation of a baby T-Rex to
a gigantic predator was too fast. They used to gain weight of about 9 tons in
just 18 to 20 years. It used to get a length of 40 to 43 ft, and height from
the hip was nearly 12 to 13 ft.
Body structure
T-Rex belonged to the family of tyrannosaur. The earlier species of
tyrannosaur had a smaller body, and they could move faster than T-Rex. The
previous species had perfectly proportioned arms. But, the t rex did not need
their arms to hunt. The massive jaws with sharp teeth were enough to catch the
prey and chomp it. The bite was extremely powerful than other animals on the
earth of that age. The bite force used to be almost 7800 pounds.
So there are many arguments about whether the T-Rex a predator or
scavenger. But from the tyrannosaurus
rex skeleton, it revealed that the T-Rex was a true predator.It
feels sad to learn that such gigantic creatures need to bid adieu, to the world
for compatibility issues with the environment. But all that is good to know
still has so many fans left behind who are keen to know about this creature and
want to have a replica of it at home or want to visit amusement parks to see
the gigantic replicas, which are look alike. One of the leading and trusted
companies of the industry that are into making of look-alike T Rex Replica is TrexFossil.
