What is the Texas pterosaur?

The most famous pterosaur known from fossils found in Texas was the Quetzalcoatlus. Quetzalcoatlus is the largest well known pterosaur, with a wingspan estimated to have been between 33 and 36 feet. Weight estimates are very difficult, as there are no modern animals with a body plan similar to that of the Quetzalcoatlus, but they range from from 150 to 550 pounds.
