Named By: Fernando Emilio Novas, Martin Kundrat, Federico Agnolína, Martín Ezcurra, Per Erik Ahlberg, Marcelo Isasi, Alberto Arriagada & Pablo Chafrat - 2012.
Classification: Chordata, Reptilia, Pterosauria, Pterodactyloidea, Azhdarchidae.
Species: A. sudamericanus (type).
Diet: Uncertain, but either a carnivore or piscivore.
Size: Uncertain due to lack of remains, but comparison of the rostrum to other similar genera has yielded an estimated wingspan of at least 5 meters.
Known locations: Argentina, Rio Negro Province - Allen Formation.
Time period: Campanian of the Cretaceous.
Fossil representation: Partial rostrum (beak).
Although named from very little fossil remains, Aerotitan is thought to be one of the azdarchid pterosaurs, and if correct, this would make Aerotitan the first known confirmed azdarchid pterosaur from South America. The azdarchid pterosaurs are a special group noted for having proportionately long necks supported by lengthened cervical (neck) vertebrae. Some of these such as Quetzalcoatlus and Hatzegopteryx grew to truly gigantic sizes, but uncertainty has shrouded what they ate. Studies of azdarchids show that they would have been most comfortable while feeding on the ground since the long neck provided little support for the head against water resistance while feeding upon the wing. Popular thinking about azdarchids at the time of writing envisions them as living more like storks, sitting on the edge of a body of water and snatching fish from the shallows, or even stalking small vertebrates like lizards and mammals through dense but low growing vegetation.
