Why did the T-Rex have such tiny arms? A new study finally provides an answer – and this is amazingly logical.
New research sheds light on origin of T. Rex's famously tiny arms: 'The head took over from the arms'
Tyrannosaurus rex's famously tiny arms may not have been an awkward evolutionary leftover after all. A new study suggests their arms shrank as giant predators increasingly relied on huge skulls and crushing jaws to take down prey. That pattern appears to have evolved multiple times across different groups of meat-eating dinosaurs. Researchers from University College London and the University of Cambridge analyzed 82 theropod species, a mostly ca…
The tiny arms of the T-Rex could be due to a brutal evolutionary effect: When hunting, the skull and jaw took over the main work.
Scientists Finally Think They Know Why T. rex Had Tiny Arms
A new study suggests T. rex and other giant predators evolved tiny arms because their massive skulls took over as the primary hunting weapon. As their bites became more powerful, their forelimbs may have gradually faded into evolutionary leftovers. Why T. Rex and Other Giant Predators Evolved Tiny Arms The famously tiny arms of Tyrannosaurus [...]
The answer to the mystery of the arms of T. rex ? A disproportionate head. It is the conclusion of a new study that pulverizes old theories: by developing an overpowering skull to hunt titanium prey, these predators have simply made their former limbs obsolete.
ON AVERAGE, RESEARCHERS KNOW THE ANSWER TO WHY TEREX HAD TINY ARMS. THE BBC HAS REVEALED WHY TEREX, ONE OF THE WORLD'S MOST POPULAR DINOSAURS, HAD TINY ARMS. THE BBC REVEALED THAT AS GIANT CARNIVOROUS DINOSAURS GOT BIGGER, STRONGER, THEIR ARMS GOT SMALLER AND SMALLER. Paleontologists, led by researchers from University College London (UCL) and the University of Cambridge, may have already discovered the answer to why large theropod dinosaurs had…
