Dendrorhynchoides

Dendrorhynchoides was a genus of anurognathid pterosaur containing only the holotype species D. curvidentatus that is known from the Middle Jurassic Tiaojishan Formation of Qinglong, northern Hebei Province, China.

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.

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.

Of the type specimen, most parts of the skull have become detached so that its shape is difficult to determine, but it was generally short and broad.

[7] A cladistic analysis by Alexander Kellner in 2003 had the same outcome, Dendrorhynchoides being found to form an anurognathid clade with Batrachognathus, that he named Asiaticognathidae.

[8] An analysis by Lü and Qiang Ji in 2006 resolved the relations even further, finding Dendrorhynchoides to be the sister taxon of clade formed by Batrachognathus and Jeholopterus.

With their smaller wingspan and skeletal body, along with very flexible joints, these traits gave them great movability to catch the small insects and prey they were chasing.

Its large eyes that were forward facing and the small claws on its appendages had researchers assuming that the species would match closely to tree bark or dark night colors to blend in with its surroundings and ambush insects for nocturnal hunting, just like what is seem with modern-day nightjars or bats.
