The Maastrichtian, Transylvanian giant azhdarchid pterosaur Hatzegopteryx sp. preys on the rhabdodontid iguanodontian Zalmoxes. Because large predatory theropods are unknown on Late Cretaceous Haţeg Island, giant azhdarchids may have played a key role as terrestrial predators in this community.

Loin d'être inutiles, les petits bras du T. rex auraient eu une fonction redoutable selon ce chercheur
Far from being useless, the small arms of the T. rex would have had a formidable function according to this researcher

His arms make you laugh. However, a T. rex claw could exert colossal pressure on its prey. These tiny members, long mocked, perhaps hide one of the most ingenious weapons of prehistory. What if we had it all wrong from the start?

Why Did T. rex Have Small Arms?
limb prey Dinosauria
Although T. rex forelimbs look tiny compared to its huge body and head, the arms of T. rex were still powerful and although they may not have played a role in prey capture and submission, they still had their uses. At Everything Dinosaur, we receive lots of questions about dinosaurs.  Frequently, the questions focus on

Mystery of Tyrannosaurus rex’s Tiny Arms May Finally Have an Answer
bone jaw predator prey Dinosauria Tyrannosaurus
Paleontologists from University College London and the University of Cambridge say the large predatory dinosaurs’ tiny arms evolved alongside massive heads and bone-crushing jaws, suggesting ancient predators increasingly relied on biting rather than grasping prey.

T. rex’s tiny arms may have evolved for a surprisingly brutal reason
jaw limb hunting predator prey Dinosauria skull
Why did T. rex have such tiny arms? Scientists now think it’s because its giant head became the ultimate hunting tool. Across multiple dinosaur groups, stronger skulls and crushing jaws evolved alongside shrinking forelimbs, especially in predators hunting enormous prey. In other words, once the bite became deadly enough, the arms may have stopped mattering.

jaw predator prey fossil Dinosauria study
Giant, fearsome octopuses may have once ruled the ancient seas, according to new research that flips the script on their evolutionary past. By uncovering exquisitely preserved fossil jaws hidden inside rock, scientists revealed that early octopuses from the age of dinosaurs weren’t shy, soft-bodied drifters—they were massive apex predators, possibly stretching up to 20 meters long and crushing prey with powerful bites.
