Santanadactylus (meaning "
. Four species have been named, but today are no considered congeneric with each other. It was a rather large pterosaur.History and species
The genus was named in 1980 by the Dutch
In 1985,
Over the years, the species of this taxon have been reassessed. Chris Bennett suggested that the hypodigm of S. brasilensis was a chimera of a pteranodontid and something else (in that the holotype and paratype belonged to different forms), S. araripensis and S. pricei were pteranodontids, and S. spixi was a dsungaripterid.[6] Wellnhofer (1991) removed S. spixi from the genus as well.[4] Kellner and Campos (1992) agreed that S. spixi was not congeneric with S. brasiliensis, but suggested that it was a tapejarid.[7] Unwin (2003) proposed that "Santanadactylus" spixi was a species of Tupuxuara based on comparison with specimens of this genus.[8] Averianov (2014) considered Santanadactylus spixi a nomen dubium probably synonymous with Tupuxuara longicristatus, and he also indicated that the paratype of S. brasiliensis was likely referable to T. longicristatus.[9] Kellner (1990) renamed S. araripensis to Anhanguera araripensis,[10] followed by Wang et al. (2008), though Veldmeijer (2003) included it in Coloborhynchus. Recent study, however, considers S. araripensis dubious.[11]
Classification
De Buisonjé first assigned Santanadactylus to Criorhynchidae (=Ornithocheiridae). Wellnhofer (1991) considered it a member of the
Paleobiology
Santanadactylus is regarded as a large pterosaur, Wellnhofer for the various species indicating a wingspan of 2.9–5.7 meters (9.5–18.7 ft).[12] De Buisonjé thought Santanadactylus brasilensis had a wingspan of 6 meters (20 ft).[14] It may have been adapted for gliding over flapping flight.[15]
