*Savage Species

A large pterosaur flies in the open sky above. It knocks into a small pterosaur, forcing it to drop its meal, before catching the abandoned fish in its oddly curved beak.

Ornithocheirus is a massive pterosaur with a colossal wingspan. Ornithocheirs are generally solitary, flying vast distances across the world in search of temporary homes and food. Once per year, however, they migrate back to their breeding grounds for mating season.

Like all pterosaurs, the wings of an Ornithocheirus is made of a thin, membranous skin. Its wings are covered in matted fur, which helps keep it warm above the cool ocean currents that keep them airborne. Unfortunately, when wet, an Ornithocheirus cannot fly, so it must be extremely careful when flying directly above the water and during rainstorms.

Combat
Ornithocheirs generally don't have to engage in combat (most smaller pterosaurs are intimidated by them), but, when forced, are more than capable of knocking targets prone and using their teethed beaks to tear at flesh.

Dive (Ex): If an Ornithocheirus makes a charge attack and lowers its altitude by at least 30 feet as part of the charge, it gains a +4 bonus on its attack roll and deals 2d8+6 points of damage with its bite if it hits.
