Taxonomic list

• section is about 50 mDomning and Demere 1984 claim that the "upper" unit has yielded no mammals and list of Demere 1994 omits record of Scapanus from the "upper" unit of Hutchison 1987a; therefore, I presume this list pertains to the lower unitearlier list of Domning and Demere 1984 is much shorter and fully duplicated here
