What is "santanadactylus"

Santanadactylus (meaning " Santana Formation finger") was a genus of pterodactyloid pterosaur from the Aptian-age Romualdo Member of the Lower Cretaceous Santana Formation, of Barra do Jardim, Araripe Plateau, Ceará Province, Brazil. Four species have been named, but today it is doubted they are part of the same genus. It was a rather large pterosaur.
