Muzquizopteryx is a genus of nyctosaurid pterodactyloid pterosaur from the Late Cretaceous period (early Coniacian stage) of what is now Coahuila, Mexico.

[1] In 2006, the type species Muzquizopteryx coahuilensis was named and described by Eberhard Frey, Marie-Céline Buchy, Wolfgang Stinnesbeck, Arturo González-González and Alfredo di Stefano.

[2] Muzquizopteryx is based on holotype UNAM IGM 8621, found in the El Rosario layers, early Coniacian-aged rocks.

[3] It consists of a nearly complete, articulated skeleton that includes soft tissue remains, among them long fossilised tendons along both sides of both lower arms.

The arms were very robust with the humerus featuring a large hatchet-shaped deltopectoral crest, indicating a strong wing musculature.
