Quetzalcoatlus
A college student found the first Quetzalcoatlus fossil in Big Bend National Park in Texas. His name was Douglas Lawson, from the University of Texas in Austin. When he was in the park, he saw a bone sticking out of a rock. Since the bone looked hollow, like the bone of a bird, he thought it was part of a flying creature – and he was right. With his professor's help, he kept digging until lots of bones from an arm and wing were found. The rest of the animal's body was missing. Many others have looked for the rest of that huge pterosaur, but it has never been found. Other fossils of Quetzalcoatlus have been found, but none are as big as the one Lawson found.
