The bent snout features twenty pairs of small teeth with an oval cross-section. That the curvature is no preservation artefact, a "post mortem" distortion, is indicated by the fact that both known snouts show it. Remarkably, all lower jaws found are straight. The wing span was initially estimated at ; however, later studies indicate that the wing span of "Prejanopterus" was probably not much (if ever) in excess of . 
The authors have assigned "Prejanopterus" to the Pterodactyloidea.
Prejanopterus
Prejanopterus is an extinct genus of pterodactyloid pterosaur from the Lower Cretaceous (lower Aptian age) layers of the Leza Formation of La Rioja, Spain. 
In 1980 a fossil site was discovered near Yacimiento de Fuente Amarga on the western slopes of the Peña Isasa. In 1993 and 1994 ten fossiliferous blocks were recovered, containing numerous disarticulated fossil bones and bone fragments, among them those of a pterosaur.
The type species "Prejanopterus curvirostra" was named and described in 2010 by Carolina Fuentes Vidarte and Manuel Meijide Calvo
