This is a life size 3d digital model skull of a Tupandactylus. OBJ, ZTL, PLY, FBX and STL files. jaw is seperated.

Tupandactylus imperator is known from four nearly complete skulls. The holotype specimen is MCT 1622-R, a skull and partial lower jaw, found in the Crato Formation, dating to the boundary of the Aptian-Albian stages of the early Cretaceous period, about 112 Ma ago. It was initially described as a species of Tapejara, but later research has indicated it warrants its own genus. The skull was toothless and had a prominent sagittal crest, only the base of which was bony: the front of the crest featured a tall bony rod extending up and back, and the rear of the crest had a long prong of bone projecting behind it. The bulk of the crest was made up of soft tissue similar to keratin, supported by the two bony struts. An additional skull described in 2011, specimen CPCA 3590, preserved more of the lower jaw, showing that like Tapejara, T. imperator had a large, asymmetrical keel-like crest on the underside of the lower jaw tip.

A 2021 study describing a very complete T. navigans specimen suggested that the two species might represent different sexes of one sexually dimorphic species, but cautioned that further study was needed to test this.
