Tropeognathus

Ornithocheirus, (now more often called Tropeognathus) was a pterodactyloid pterosaur from the early Cretaceous.

Facts
Tropeognathus is a genus of large pterosaurs from the late Cretaceous Period of South America. It was member of the Ornithocheiridae (alternately Anhangueridae), a group of pterosaurs known for their keel-tipped snouts, and was closely related to species of the genus Anhanguera. It is known primarily for the species Tropeognathus mesembrinus, though a second species, Tropeognathus robustus, has been named in the genus.

This pterosaur died out 108 MYA.

Giant of the Skies
The 4th episode of WWD focused primarily on an old, lone male Ornithocherius. In this episode, the pterosaur was depicted as a solitary nomad, similar to the modern species of albatross, coming together only to mate. Unlike other pterosaurs, such as Tapejara (depicted at the beginning of the same episode), Ornithocheirus leked and mated on flat ground, not on cliffs. Like Tapejara, however, this pterosaur was also sexually dimorphic with the females have slimmer, less ornate bills than the males.

This pterosaur was capable of flying for a day or more without any rest, but rainy weather would ground it. Ornithocheirus suffered from tick-like parasites and fed on fish that it caught on the wind or stole from smaller pterosaurs. It was also a cannibal and fed on its own kind that died for various reasons, like physical exhaustion or sunstroke.
