Ctenosauriscidae is an extinct family of pseudosuchian archosaurs within the clade Poposauroidea.[1] Ctenosauriscids existed in Africa, Asia, Europe and North America during the Early Triassic to the Middle Triassic period (latest Olenekian to Anisian stages).[1] All species had large "sails" on their backs. Ctenosauriscids are among some of the earliest archosaurs and represent the first global radiation of the group.[2]
