Parectypodus foxi (Storer, J.E., 1991). This Maastrichtian (Late Cretaceous)-age species from the
Frenchman Formation of Saskatchewan is estimated to have weighed about 80 g.
Parectypodus laytoni (Jepsen, G.L., 1940; Sloan, R.E., 1966), also known as Ectypodus laytoni (Jepsen 1940). Remains are known from the Lower
Tiffanian (Middle-Late Paleocene) Princeton Quarry,
Wyoming (United States). This species has been cited as a descendant of P. sinclairi. It is a small species, having a weight of perhaps 10 g.
Parectypodus lunatus (Krause, D.W., 1982), also known as P. childei (Kühn, 1969). From the
Wasatchian (Lower Eocene) Pocket Quarry of
Colorado and Wyoming. This is a late species, having a weight of about 35 g.
Parectypodus sinclairi (Lamb, 1902; Clemens, 1964a). Known from the Puercan-Torrejonian (Paleocene) of Gidley Quarry,
Montana, Wyoming, and
Alberta, Canada. This species has been cited as having been derived from Mesodma formosa. It is a smaller species of about 15 g.
Parectypodus sloani (Schiebout, J.A., 1974). Fossils of this species have been found in the
Torrejonian (Paleocene)-age beds of
Big Bend,
Texas.
Parectypodus sylviae (Rigby, J.K., 1980; Sloan, J.E., 1987) (=Ectypodus aphronorus (Sloan 1987), P. pattersoni (Sloan 1987)). Remains are known from the Torrejonian (Paleocene)-age Swain Quarry of Montana and Wyoming. The body weight of this species has been estimated as 15 g.
Parectypodus trovessartianus (Cope, E.D., 1882; Van Valen & Sloan, 1966). From the Puercan-Torrejonian (Paleocene) of the
San Juan Basin,
New Mexico. The body mass of this species has been estimated to have been around 90 g.
Parectypodus vanvaleni (Sloan, J.E. 1981). From the Puercan (Paleocene) of the San Juan Basin, New Mexico.
