Baryonyxportrayed here by an animatronic museum modelhad an unusual skull with a long, curved jawline, which resembled that of a modern-day gavial crocodile.
Though the British dinosaur looks like a typical carnivore, several clues suggest a fish diet.
For instance, the reptile had stout, conical teeth, rather than the bladelike teeth of meat-eaters. Scientists also found partially digested fish scales and teeth in an excavated specimen.
" We wanted to establish which it was more similar to, structurally and functionallya dinosaur or a crocodile," said Emily Rayfield of the University of Bristol in the United Kingdom, the lead author of a new study on the animal in the Journal of Vertebrate Paleontology.
The results suggested a close resemblance to the gavial.
