Ctenosauriscus koeneni
Taxonomy
Ctenosaurus koeneni was named by Huene (1902). Its type specimen is GZG.V.4191, a set of vertebrae (Partially articulated series of posterior cervical, dorsal, sacral and anterior caudal vertebrae), and it is a compression fossil. Its type locality is Bremketal, east of Reinhausen, which is in a Spathian fluvial sandstone in the Solling Formation of Germany. It is the type species of Ctenosauriscus, Ctenosaurus.
It was recombined as Ctenosauriscus koeneni by Kuhn (1964), Krebs (1969), Butler et al. (2011).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. J. Butler et al. 2011 | Poposauroid archosaur characterised by the following unique combination of characters: (1) posterior cervical, dorsal, sacral and anterior caudal vertebrae with elongated neural spines that form a symmetrical ‘sail’ (shared with Arizonasaurus, Xilousuchus, Lotosaurus and Hypselorhachis); (2) extreme elongation of dorsal neural spines, with the longest neural spine more than 12 times the length of the centrum of its vertebra (probably shared with Arizonasaurus); (3) neural spines strongly expanded anteroposteriorly at their apices, reaching ~190% of the anteroposterior length of their bases (probably shared with Hypselorhachis); (4) pre- and postzygapophyses of the dorsal vertebrae are large, robust processes that extend a substantial distance anterior and posterior to the articular faces of the centrum (probably shared with Hypselorhachis). |
