Spondylophryne

Spondylophryne villanyensis is a name given to a prehistoric amphibian placed in the family Discoglossidae (=Alytidae). It was described based on material from Villány, Hungary. Later studies have criticized the extreme brevity of the description and lack of illustration;  the name could be considered a nomen nudum.
