At a total mass of over 200 lbs., and a wingspan of approximately 30 ft., Quetzalcoatlus (named after a Toltec serpent god) would've needed a very strong thermal to be airborne, and much of the time it walked on land, stalking prey like a Marabou Stork (Leptoptulus crumeniferus) would.Those living along a coast would include fish (as depicted here in their diet, while inland populations would've hunted smaller reptiles (perhaps primitive mammals as well) that they could grab. A type of pterosaur (pterodactyl kin), Quetzalcoatlus lived about 70 million years ago in (what is now) Texas and northeastern Mexico. Mesozoic Era, Cretaceous Period.

.Fossils of both (about 200million years old) were discovered in Antarctica, which at the time they existed was 400 miles north of its present location, and had a climate more like New Zealand (temperate rainforest along the coast, snow-capped mountains inland).
