Between two and four genera of pterosaurs are present in the formation, depending on the taxonomy. All but Nyctosaurus belong to the Pteranodontidae family of the suborder Pterodactyloidea, though even Nyctosaurus has occasionally been included in that family, and is at least a close relative of the pteranodonts.

Later, Platylithophycus was re-identified as a sepiid cephalopod, based ...
