Comahuesuchidae is a family of notosuchian crocodyliforms. Constructed in 1991, it includes the genera ''Comahuesuchus'' and ''Anatosuchus''. Among the characteristics that are unique to this family is an external naris that is inset into the tip of the snout. There is also a diastema, or gap between the teeth, at the tip of the upper and lower jaws. Both ''Anatosuchus'' and ''Comahuesuchus'' have maxillary tooth rows in the upper jaw that extend out and over the dentary tooth rows of the lower jaw. Several recent phylogenetic analyses of notosuchians have placed ''Anatosuchus'' outside of Notosuchia altogether, and therefore outside Comahuesuchidae. If this is true, ''Comahuesuchus'' would be the only member of Comahuesuchidae. ==References==
