Two new Pleistocene (Kansan) molluscan local faunas from Trego County,Kansas
Two new Pleistocene local faunas, the cedar Bluff and the Lone Tree, are reported from Trego County, Kansas. Twenty- three taxa were collected from the Cedar Bluff l.f. along the Smoky Hill River. The Lone Tree l.f. contains twenty-one taxa which were collected just below an ash bed. The mollusks as...
