If you run you’ll only die tired.


Nanotyrannus was the cheetah of the dinosaur world, its speed making it even more terrifying than the great T. rex, suggests University of Alberta research.

Nanotyrannus was the cheetah of the dinosaur world, its speed making it even more terrifying than the great T. rex, suggests University of Alberta research.
When it comes to speed, the five-meter long Nanotyrannus led the pack, leaving the swift Tyrannosaurus rex and known juveniles of other tyrannosaur species in the dust. Nanotyrannus’ status as a distinct species has been debated for years due its strong resemblance to a juvenile T. rex, but its uniquely elongated limbs now indicate that Nanotyrannus really was its own distinct species.
“In terms of Cretaceous ecology, T. rex was the lion and Nanotyrannus was the cheetah. As far as I’m concerned, it was the scariest dinosaur,” says U of A paleontologist Scott Persons, who led the study in leg length among carnivorous dinosaurs as part of his doctoral research.
“Sure, it might take it four to five bites to eat you, while T. rex could do it in just one or two, but eaten is eaten — and no dinosaur was better adapted to chase you down.”
