Tyrannosaurus Rex
You thought you knew all about T-Rex right? That it is the same old Theropod Dinosaur didn't you? Well, think again...Science has been rewriting the history of T-Rex until today.
On Discovery Science channel was T-Rex: History Rewritten program. It was an amazing worth watching show. In the beginning T-Rex was thought to be a very slow moving predator that walked straight up dragging its tail on the ground. But later we saw T-Rex moving as we did in Jurassic Park.
The speed has also been reduced to about 15-20 miles perhour. Being slower than previously thought does not exclude T-Rex from being a predator to a primarily scavenger, T-Rex being slower had its own item of preys, which were the massive, slow moving Dinosaurs, such as the Triceratops.
Scientists have also become able to calculate the age of each specimens as they discovered growth rings that are much if not exactly similar to the American Alligator. Having discovered this, they discovered that all the T-Rex fossils discovered so far are teenagers...like from 12 to 18 years old. Biggest and oldest fossil ever discovered would be famous T-Rex Sue:
At the Field Museum, Sue stands 13 feet high at the hips and 42 feet long from head to tail. One of the only pieces of Sue that is not mounted is her 5-foot-long skull, which is too heavy to be placed on the steel armature that holds together her more than 200 fossilized bones. Sue is also the most complete fossil ever discovered and with Sue were several juveniles. Which later told us that T-Rex was a social animal, that looked after their babies. And even moved in groups like Lions to tackle down massive preys.
Scientists can now also sex T-Rex, I don't remember this exactly but having discovered T-Rex's soft tissue in a thigh bone:
...have told us that it was a female because the soft tissue that was developed is exactly like of the birds that develop them when pregnant. And finally discovering the previously lived Tyrannosaurs told us that T-Rex does not belong to the previously thought Carnasauria family of Theropods, but of another family of the Theropods. Whose name I forgot
...
So the Tyrannosaurus was at first a small predatory Dinosaur ( that had feathers even before birds originated ) that evolved into the gigantic Tyrannosaurus Rex. Feathers played a role for thermoregulation, so it wouldn't be surprising to see new born T-Rex with feathers looking like chicks. This clears up the fact that birds today evolved from Dinosaurs. Here is Guanlong, the earliest known Tyrannosaur:
Now, going back to Sue and the age of T-Rex. Knowing that all were teenagers, Sue the oldest and biggest is discovered to have died at her 29th year. And her fossil showed that she had such a tough life, yet she was very resilient, showing what a hardy predator T-Rex was. T-Rex pushed its envelop during its life time, did best in what it was doing, lived fast and died young showing that none of them ( fossils discovered ) had grown to their full size.
And I would like to end the topic by speaking of T-Rex's estimated bite force. It is estimated to be 20,000 pounds / 10,000 Kilograms...and its skull is designed perferctly to absorb shocks from the impact. T-Rex's bite basically says that it did not need to depend upon its small, what appearing to be useless tiny arms. Those jaws in another word means Death, one bite takes a chunk out of you. And this bite was discovered upon a Triceratop's fossils...which looked real bad.
T-Rex had an acute sense of smell, vision and hearing, had a size of brain considered impressive back then, long although not so large but it's not the size, but how you use it and T-Rex did it perfectly. Don't miss the program if it's on. T-Rex had all it needed and having survived longer than any Dinosaurs, T-Rex will always be the King or the Queen of Dinosaurs.
