The heaviest Tyrannosaurus Rex ever discovered was unveiled last week in The Anatomical Record, weighing in at an estimated 19,500 pounds under its existence.
Paleontologists first dug up "Scotty" in 1991 at a place in Saskatchewan, Canada where they found about 65% of their skeleton. The dinosaur's eight-inch femur transversely impressed the team and suggested that its two legs could have carried more than 19,500 pounds.
But even with Scotty's supreme role in the hierarchy of predatory dinosaurs, damage like a broken and healed rib, an infection of bone growth between two teeth and crushed horse edges, which is probably due to another test, shows that it has not led to a easy life.
Intended to be at least 28 years old (a senior in tyrannosaur world) Scotty's tenant suggests that large predator dinosaurs were much older and larger than paleontologists originally considered to be based on the data they have on available fossils.
"As more copies of the other theropods are found, we will find their Scottys: their particularly large, especially old, individuals," says study director Scott Persons. "It would not surprise me that these animals prove to increase the size of body size ̵
