Species

Ponerosteus is a dubious genus of archosaur which was first identified as "Iguanodon exogirarum" by Antonín Frič in 1878 for a specimen from the Cenomanian (Late Cretaceous of the Czech Republic, near Holubice by Kralupy nad Vltavou[1]). He later (1905) renamed it Procerosaurus, unaware that this name was already in use (von Huene, 1902). It was renamed Ponerosteus exogyrarum (species name amended) by George Olshevsky in 2000; however, the taxon is considered a nomen dubium by most, as the type material is extremely poor, being apparently an internal cast of a tibia from an animal that may or may not be a dinosaur. The name Ponerosteus can be translated as "bad", "worthless", or "useless bone", which accurately describes the nature of the material.
