If most people know one thing about pterosaurs (well one correct thing rather than them being flying dinosaurs or bird ancestors) it's that they got really big. At the top end they hit over 10 m in wingspan and probably over 250 kg, massively bigger than the largest flying birds (living or extinct). And all the real giants belonged to one group – the azhdarchids. These long-necked monsters were a real mystery for decades but a flurry of discoveries and research in recent years means we now have an excellent understanding of their ecology and weird proportions.   Links: Dave's blog post about the Canadian azhdarchid he (fairly) recently named https://archosaurmusings.wordpress.com/2019/09/10/welcome-cryodrakon-a-gaint-canadian-azhdarchid-pterosaur/ Darren Naish's blog about the recent big work finally describing Quetzalcoatlus https://tetzoo.com/blog/2021/12/8/the-quetz-monograph-lives
