My book never mentioned anything like that, but the BBC documentary Walking with Dinosaurs depicts Ornithocheirus with a "beak crest" similar to that of Anhanguera and Tropeognathus. Obviously, the documentary doesn't know everything, and I also know that little is known about Ornithocheirus, as no complete skeletons have ever been found, but I was wondering if the aforementioned trait has had any potential evidence.


yes Ornithocheirus does have an expansion to both the upper and lower jaws. These are part of the skull, but would have been covered in skin and perhaps even part of the beak as well which would make them larger in life.
