Just how serious was the killer T rex dinosaur's bite? Researchers from the University of Bristol have now revealed that the feeding style and dietary preferences of dinosaurs were closely linked to how wide they could open their jaws.
The dreaded Tyrannosaurus rex and its dinosaur cousins were successful predators partly due to unique teeth designed like steak knives that allowed them to tear through the flesh of their prey, a new study has found.
Paleontologists have determined that ray-finned fish - the world's most diverse vertebrates - began their dominance in the oceans 66 million years ago after the mass extinction that wiped out dinosaurs from the Earth.
Using new three dimensional modelling, scientists have found that the giant sauropod dinosaur, Dreadnoughtus, discovered by palaeontologists in South America in 2014, was not as large as thought earlier.
