|Ornithocheirus mesembrinus life reconstruction by Christopher DiPiazza|
The genus, Ornithocheirus, actually includes several different species that over the years have changed names a few times. The one I
|Skull from Ornithocheirus mesembrinus.|
In addition to being rather large, this species of Ornithocheirus had a long tapering snout, lined with straight, pointed teeth and a bony half-disc-shaped crest on its upper and lower jaws. This pterosaur probably specialized in hunting fish and other marine prey. The crests could have allowed it to dip its mouth into the water to catch food without worrying about drag while on the wing. It and other members of its family also had really large heads, long arms but proportionally teeny-tiny bodies and hind limbs. This is probably an evolutionary result of an animal that spends a lot of its time soaring over the water (think about pelicans and albatross). When alive, it would have had large and well developed neck, chest and arm muscles but relatively wimpy hind legs. I think I know a few dudes at the gym who could relate to Ornithocheirus now that I think about it.

Ornithocheirus has also made an appearance as a major character in an animated series that aired on Cartoon Network called "Secret Saturdays". The character's name was "Zon" because she came from the Amazon. Pretty accurate!
