Darwinopterus

Darwinopterus (meaning "Darwin's wing") is a genus of pterosaur, discovered in China and named after biologist Charles Darwin.[1] Between 30 and 40 fossil specimens have been identified,[2] all collected from the Tiaojishan Formation, which dates to the middle Jurassic period, 160.89–160.25 Ma ago.[3][4] The type species, D. modularis, was described in February 2010.[1] D. modularis was the first known pterosaur to display features of both long-tailed ('rhamphorhynchoid') and short-tailed (pterodactyloid) pterosaurs, and was described as a transitional fossil between the two groups.[5] Two additional species, D. linglongtaensis and D. robustodens, were described from the same fossil beds in December 2010 and June 2011, respectively.[6][7]
