Mistakes have been made when distinguishing between male and female dinosaurs, new research has revealed.

There has been much debate as to whether scientists have been correctly identifying the sex of dinosaur fossils and a new study from academics at Queen Mary University of London has proven that it is extremely difficult to spot the difference.

The team studied over 100 gharials, an endangered species of crocodile with similar traits to dinosaurs, and found the only difference was on their snouts.

Dr. David Hone, from the university, said: ''Our research shows that even with prior knowledge of the sex of the specimen, it can still be difficult to tell male and female gharials apart.

''With most dinosaurs we don't have anywhere near that size of the data set used for this study, and we don't know the sex of the animals, so we'd expect this task to be much harder.''
