STRATIGRAPHIC SETTING OF THE FOSSIL LAKE FAUNA
BY IRA S. ALLISON*
Mammalian fossils from the Fossil Lake locality of northern Lake County, Oregon, found mainly on the surface as deflation residuals, occur in place near the top of the main body of Pleistocene lake sediments and are associated with a minor unconformity, flat-pebble conglomerates, disturbed bedding, and other shallow-water features. The animals evidently had access to the area after the lake level had declined more than 200 feet. Beds above the principal mammal horizon yield numerous bones of birds and fish.
MAMMALIAN AND AVIAN ICHNITES IN DEATH VALLEY
BY H. DONALD CURRY†
Fossil tracks of mammals and birds, unlike those of lower animals, are seldom recorded. In Death Valley, California, ichnites of this type are relatively common and occur at several localities in rocks of late Tertiary and Pleistocene age. The Copper Canyon region in particular has yielded hundreds of . . .
