A short video recapitulating recent theories and discoveries about t-rex...

" Tyrannosaurus Rex, often referred to as T-rex, belongs to the genus of large theropod dinosaurs, a closely related group within the coelurosaurian theropods. This group can be further classified into two subfamilies: the relatively slender albertosaurines, represented by species like Albertosaurus and Gorgosaurus. and the later larger tyrannosaurines, which include not only the famous Tyrannosaurus rex, but also other genera, such as Daspletosaurus, and the Asian Tarbosaurus.

The name 'Tyrannosaurus rex' itself translates to 'Tyrant lizard' from Greek and 'king' from Latin. The origins of these creatures can be traced back to the middle Jurassic period, within the superfamily Tyrannosauroidea. Just like other megatheropods, T-rex had muscular hind limbs adapted to support its huge bulk. But despite having brawny legs, these beasts likely weren't built for speed. T-rex's estimated pace was around 4.6 km/h. with estimated sprinting speeds around 19 km/h. If any faster, and T-rex risked shattering its bones under its own weight. The original ancestors of T-rex equipped with longer three-fingered forelimbs. However, when they continued to evolve into massive sizes, their hands shrank in size and retained only two functional digits.

Another remarkable aspect of T-rex is its massive and exceptionally sturdy skull, stretching over 5 feet long. Sporting formidable jaws lined with some 60 serrated teeth, and some even measuring up to 12 inches in length, they rank as the most dangerous carnivore in the dinosaur kingdom. Teamed with powerful jaw muscles generating forces of 35,000 newtons, equivalent to 7800 pounds per square inch. " Reply
