Geology. 1913] Merriam: Tapir Remains from Pacific Coast Region 173 The lower fauna is not yet well enough known to permit definite reference to a stage of the standard time scale, but seems to be not older than late Pliocene or younger than the earlier portion of the Pleistocene. The section from which the tapir tooth was obtained has been described by Diller,s who refers to an upper horizon as the Elk River Beds. A collection of marine shells from these beds examined by Dall was referred to as "probably Pleistocene, all the species seeming recent, but they may be of the Merced horizon. . They are not older than the newer ; The lower zone at Elk River as described to the writer by Martin is pos- sibly referred by Diller to the Cape Blanco Beds, the equiva- lent of the Empire beds. The fauna from the exposures of the Blanco is considered by Diller as Miocene. Mr. Martin believes that the lower horizon of blue-gray argillaceous sand- stone is later than the Empire formation which occurs lower down in the section in the cliff farther north. According to Martin the fauna of this blue-gray argillaceous sandstone is much more recent in character than that of the Empire Beds farther north. The tapir specimen is reported from the lower Fig. 2. Tapirus, near liaysii calif amicus, n. subsp. Superior molar series, natural size. From early Pleistocene or late Pliocene marine deposits three miles south of Cape Blanco, Oregon. The tapir specimen obtained at Cape Blanco consists of a portion of a maxillary bone with the three molar teeth well pre- served and but little worn (fig. 2). 5 Diller, .1. S., TT. S. Geol. Sun .
