KOMPA.com – Tyrannosaurus Rex it is one particular of the most ferocious predators that have ever lived on Earth.
With a huge human body, sharp enamel, and jaws so effective they could crush a vehicle, this well-known carnivore dominated the wooded river valleys of western North The us during the Late Cretaceous, some 68 million a long time in the past.
Possessing monumental energy, of training course T.rex he can try to eat nearly anything he would like, which include dinosaurs of his own form.
Paleontologists have located some surprises in T. rex’s taking in behavior.
Described by Countrywide Geographic, The most recent discovery is a 66-million-12 months-aged scratch on a tyrannosaurus limb bone found in Wyoming, United States (Usa).

These scratches have been plainly built by substantial predators with serrated enamel.
Study chief Matthew McLain reported T. rex was the only carnivore in existence at the time able of making these types of a chunk.
T. rex was earlier categorized as a cannibal. In 2010, Nicholas Longrich and colleagues documented 4 a lot more T. rex bones that contains divot and gouge that could only be developed by members of the exact same species.
On the other hand, this does not signify that T. rex only chews the continues to be of its species.
Thanks to fossilized traces of damaged bones and fossilized feces, paleontologists have a very excellent concept of what T. rex ate.

In a 2012 study of the chunk force of prehistoric predators, researchers believed that an grownup T. rex could chunk with a force of up to about 57,000 Newtons or 5,805 kg.
Although not the strongest chunk of all time, it seems that the chunk power of a T. rex was ample to knock out an Edmontosaurus or Triceratops.
Even though numerous T. rex bite marks are identified on “clean” fossil bones, these kinds of as cannibalized T. rex bones and some Triceratops specimens, there are many Edmontosaurus fossils with healed chunk marks alongside the back.
A person of the wounded Edmontosaurs even experienced the idea of a tyrannosaurus tooth embedded within just it.
This discovery is evidence that the dinosaurs really captured their prey, not just carrion.

How T. rex eats its prey
Irrespective of no matter whether T. rex hunted prey or identified a rotting carcass, fossil and experimental evidence indicates that T. rex utilizes a exclusive way of having its prey.
With its little arms, the T. rex is unable to try to eat by word of mouth. Dinosaurs also could not chew.
Alternatively, T. rex swallowed meat and bones entire, applying its sturdy neck muscle mass to throw its head back and fall the meat into the back of its mouth.
This behavior is called inertia, a actions shared by birds and crocodiles.
In a 2007 review, researchers estimated that T. rex’s neck muscle groups were being potent enough to toss 49 kg of meat up to 4 meters high into the air.
