Ponerosteus is a dubious genus of extinct archosauromorph from the Late Cretaceous ( Cenomanian-aged) Korycanar Formation of the Czech Republic that was initially identified as a species of the dinosaur Iguanodon. [1]
The type, and currently only, species is P. exogyrarum. [2]
The holotype, NAMU Ob 40, consisting solely of an internal cast of a tibia, was discovered near Holubice, Kralupy nad Vltavou, and was first identified as a dinosaur, which was named " Iguanodon exogirarum" (later "Iguanodon exogyrarum") by Antonín Frič in 1878. [1] [3] He later (1905) renamed it Procerosaurus, [4] unaware that this name was already in use ( von Huene, 1902 [5]) for what is now a synonym of Tanystropheus. NAMU Ob 40 was renamed Ponerosteus exogyrarum (species name amended) by George Olshevsky in 2000, and Olshevsky considered Ponerosteus to be a nomen dubium; [2] the holotype has since been put on display at the National Museum in Prague. [2]
The name Ponerosteus can be translated as "bad", "worthless", or "useless bone", which describes the fragmentary nature of the holotype. [6]
Although initially identified as being a dinosaur belonging to the genus Iguanodon, [1] Ponerosteus is currently classified within Archosauromorpha. [2]
