Ctenosauriscidae was named byOskar Kuhn in1964 to include the genusCtenosauriscus.[3] It is astem-based taxon defined by Richard J. Butler, Stephen L. Brusatte, Mike Reich, Sterling J. Nesbitt, Rainer R. Schoch and Jahn J. Hornung in 2011 as "the most inclusive clade containingCtenosauriscus koeneni but notPoposaurus gracilis,Effigia okeeffeae,Postosuchus kirkpatricki,Crocodylus niloticus,Ornithosuchus longidens, orAetosaurus ferratus".[2] Thecladograms below follows a 2011 analysis by Butleret al., the first based on Brusatteet al. 2010[4] and the second based on Nesbitt 2011.[1]
