Sierra Perenchiza Formation
Introduction The '''Sierra Perenchiza Formation''' is a late Campanian to late Maastrichtian geologic formation in Spain. Dinosaur, pterosaur, turtle, lissamphibian, frog and albanerpetontid remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus and the crocodylomorphs ''Acynodon'', ''Doratodon ibericus'' and ''Musturzabalsuchus'' are also known from this formation.
