<human>: Is there any information available about the pterosaurs?
<bot>: Yes, there is a lot of information about the pterosaurs. Pterosaurs are a group of extinct flying reptiles that lived during the Mesozoic Era, which lasted from 252 to 66 million years ago. They were the first vertebrates to evolve powered flight and were some of the largest animals ever to have lived on Earth. There are many different types of pterosaurs, including long-necked pterodactyls, short-winged pteranodons, and toothless pterosaurs such as the Pteranodon. Many of these creatures had wingspans of up to 10 meters (33 feet).
