Not All Giant Dinosaurs Had Bone-Crushing Bites, Study Finds
By Science Correspondent
A new study has revealed that while Tyrannosaurus rex had a skull built for powerful, crushing bites, other meat-eating dinosaurs like spinosaurs and allosaurs had much weaker bites and relied on slashing and tearing instead.
Published in Current Biology, the research analysed the skulls of 18 species of theropod dinosaurs using 3D scanning and biomechanical modelling.
The team found surprising variation in bite strength—even among similarly sized predators.
“Carnivorous dinosaurs evolved very different skulls and feeding styles,” said lead author Andrew Rowe from the University of Bristol. “T. rex was like a crocodile, built for strength, while others were more like Komodo dragons, designed to slash flesh.”
The findings suggest that large, bipedal predators didn’t all evolve the same way.
Despite their size, dinosaurs like Giganotosaurus had relatively lighter bite forces, showing that evolution produced multiple solutions for being a giant carnivore.
The research highlights the diversity of dinosaur ecosystems, where different species could thrive with specialised hunting strategies rather than competing directly for the same prey.
