The genus Cernaysia ("from Cernay") was named by Vianey-Liaud M. in 1986 based on two species. It has also been known as Carnaysia.
Fossil remains of the species Cernaysia davidi (Vianey-Liaud M. 1986) were found in Puercan (Lower Paleocene) strata of the San Juan Basin of New Mexico, (United States). Remains of the species Cernaysia manueli (Vianey-Liaud M. 1986) were found in Upper Paleocene strata from Cernay, France.
