In terms of how long they dominated the skies, the pterosaurs (clade Pterosauria) were the most successful fliers of all time. They were the first vertebrates to fly, the longest aloft with a fossil record of over 150 million years, and the largest organisms ever known to fly with wingspans of over 32 feet. They are also the only flying organisms to do us the disservice of going entirely extinct. Despite over 230 years of study, their evolutionary relationships and many aspects of their biology are still poorly understood. I have created this website to promote and disseminate pterosaur research.
