At the time of discovery, Giganotosaurus was believed to be the largest theropod before the discovery of another carnivorous dinosaur species about two years later. As far as carnivorous dinosaurs go, the semi-aquaticSpinosaurusis the longest. The dinosaur was found in North Africa in about the ...
Below the nostril in the upper jaw was a “subnarial gap” – a kink in the jaw bone forming a gap between the front and back teeth. This is also seen inSpinosaurus. To some paleontologists, the presence of a subnarial gap is evidence that Dilophosaurus, likeSpinosaurus, was a fish-e...

The research sheds new light on a conundrum that has perplexed paleontologists. Dinosaurs had a joint in the middle of their lower jaws, called the intramandibular joint, which is also present in modern-day reptiles. Previous research has suggested this joint was flexible, like it is in snakes...
