Dendrorhynchoides

Dendrorhynchoides was a genus of anurognathid pterosaur containing two species known from the Middle Jurassic Tiaojishan Formation of Qinglong, northern Hebei Province, China.

The genus was first named Dendrorhynchus in 1998 by Ji Shu'an and Ji Qiang, but that name proved to be preoccupied by a parasitic protozoan named in 1920 by David Keilin. It was therefore renamed in 1999. The type species is Dendrorhynchoides curvidentatus. The genus name is derived from Greek dendron, "tree" and rhynkhos, "snout" in reference to it being assumed a tree-dweller and presumed a close relative of Rhamphorhynchus. The specific name means "curved-toothed" in Latin. A second species, D. mutoudengensis, was described in 2012.

The genus is based on holotype GMV2128, a fossil originally discovered around 1995 and obtained by science from illegal fossil dealers who first prepared it. It consists of a near-complete skeleton of a subadult individual and is crushed. Most elements are present, exceptions include the sternum, the tail end, sacrals and the fourth phalanx of the wing finger. This specimen was originally thought to be from the Jianshangou Bed of the Yixian Formation, dated to about 124.6 million years old. However, the specimen was obtained by amateur collectors and altered to contain a piece of a dromaeosaurid tail before being studied. Lü and Hone (2012) considered it more likely that the holotype of D. curvidentatus was actually found in the Middle Jurassic deposits; the authors note that all other Chinese anurognathids are Jurassic in age, and that Jeholopterus was also initially thought to be a Cretaceous taxon until subsequent studies established it to be from the Jurassic.
