Sericipterus
''Sericipterus'' is an extinct genus of rhamphorhynchid pterosaur. It is known from the Late Jurassic (early Oxfordian age) Shishugou Formation in Xinjiang, China.
The genus was named and described in 2010 by Brian Andres, James Matthew Clark and Xu Xing. The type species is ''Sericipterus wucaiwanensis''. The generic name is derived from Latin ''sericum'', "silk", a reference to the Silk Route, and from a Latinised Greek ''pteron'', "wing". The specific name refers to the Wucaiwan area, itself meaning "five-colour bay" because of the many-coloured layers.
The holotype specimen, IVPP V14725, consists of partly crushed, disarticulated bones that are largely preserved three-dimensionally. The wingspan has been estimated at at least 1.73 metres. The skull of ''Sericipterus'' is similar to those of the "rhamphorhynchoids" (i.e. basal pterosaurs) ''Angustinaripterus'' and ''Harpactognathus''. It had three bony crests: a low crest on the snout, a short low parietal crest on top of the skull and a short traverse crest connected to the front edge of the latter. The parietal crest is the first reported for a non-pterodactyloid pterosaur. The same is true for the rosette, bearing two pairs of forward pointing laniaries, formed by a narrowing of the snout behind these long fangs. Another probably five pairs of teeth were present in a more posterior position in the upper jaws. The number in the lower jaw is unknown. Except for the first rather straight pair, the teeth were recurved, sharply pointed, covered with smooth enamel and circular in cross-section but equipped with two keels providing cutting edges.
''Sericipterus'' has, after a comprehensive new cladistic analysis of the Pterosauria, been placed as the sister taxon of ''Angustinaripterus'' in the Rhamphorhynchinae, a clade which also includes other large-bodied "rhamphorhynchoids", living inland as predators of small tetrapods and preserved in terrestrial sediments.
