Taxonomy
Ctenosauriscus was named by Kuhn (1964). Its type is Ctenosaurus koeneni. It is the type genus of Ctenosauriscidae. It was considered monophyletic by Butler et al. (2011).
It was assigned to Poposauroidea by Weinbaum and Hungerbühler (2007); and to Ctenosauriscidae by Kuhn (1966), Krebs (1969), Kuhn (1971), Carroll (1988), Butler et al. (2011) and Sennikov (2012).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. J. Butler et al. 2011 | Diagnosis as for type and only species. 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). |
