Erpetonyx was a genus of bolosaurid reptile, described in 2015. It lived in Gzhelian stage of the Carboniferous period. It is one of the few fossil taxa known from the Canadian province of Prince Edward Island. It is known from a single small, complete, and articulated specimen. It is the oldest currently known parareptile, and has brought back ghost lineages for several groups within the clade.
