Tyrannosaurus Rex and Other Terrifying Predatory Dinosaurs Had Itty-Bitty Arms. Scientists May Have Finally Figured Out Why
Researchers found reduced forelimbs in 82 theropod species were tied more closely to robust skulls and jaws than to body size, they said.

Tyrannosaurus Rex and Other Terrifying Predatory Dinosaurs Had Itty-Bitty Arms. Scientists May Have Finally Figured Out Why
A new study suggests that certain theropods—two-legged, mostly meat-eating dinosaurs—had shrunken forelimbs as an evolutionary trade-off for their strong skulls
Here's how Tyrannosaurus ended up with a big head and small arms
Tyrannosaurus rex possessed a preposterously massive skull - 5 feet long (1.5 meters) and built to enable bone-crunching bite force - but presented preposterously puny arms. And many other meat-eating dinosaurs shared this mismatched combination of traits. So how did this come to be?Researchers studying this phenomenon have now documented how skull robustness in meat-eating dinosaurs started to evolve first, as plant-eating dinosaurs that they…
T. rex had massive jaws but tiny arms: Scientists now know why
A new study documents that the robustness of skulls in carnivorous dinosaurs began to evolve first, a direct response to the increasing size of the plant-eating dinosaurs they hunted, shortly after dinosaurs became Earth's dominant land animals
For decades, the small arms of Tyrannosaurus rex were one of the greatest mysteries of modern paleontology. Now, a team of international researchers from University College London and the University of Cambridge believe they have finally found an answer.This finding radically changes the scientific view on one of the most famous and feared dinosaurs of all time.The arms of the T-rex The study analyzed 82 distinct species of theropod dinosaurs, w…
Why did Tyrannosaurus rex have such small arms compared to the rest of his body? A new investigation suggests that the giant predator sacrificed his front limbs as he evolved a larger and more powerful head.
