Taxonomic list

• upper part, middle oreodont zone
NW 1/4 sec 32 T 24N R 61W
based on Prothero 1996c this is definitely in a normal zone
clearly Orellan based on age ranges given by Emry et al. 1987; correlated with Orella B by Schultz and Stout 1955
a specimen of Merycoidodon culbertsoni from the "middle Oligocene" may be from this locality because the lower Brule is "middle Oligocene" in Schlaikjer's terminology
