Tacuadactylus

Tacuadactylus is a genus of ctenochasmatid pterosaur from the Late Jurassic of Uruguay.

==Discovery and naming== A snout found near Batoví was in 2016 reported as a saw fish, the oldest known member of the Pristidae. Subsequently, a CAT-scan showed that the presumed perpendicular teeth of the fossil were in fact sediment fillings of the tooth sockets, which themselves pointed obliquely to the front as with pterosaurs. In 2018, the specimen was described as the first pterosaur found in Uruguay but not yet named.
