Upper Eocene Orbitoid Foraminifera from the Western Santa Ynez Range, California and their stratigraphic significance

Abstract

In December, 1929, Dr. W.S.W. Kew and Mr. H.L. Driver invited me to visit with them a locality on the west side of Canada de los Sauces, on the south slope of the western Santa Ynez Range about two miles northwest of Sudden, where they had discovered well-preserved specimens of a small Discocyclina in a soft limestone. When we visited this locality we also found almost equally well-preserved specimens of a small stellate “Discocyclina.” K.E. Lohman and S.W. Lohman, of the California Institute of Technology, accompanied me on a later trip to the same locality in March, 1930, when additional material was collected and the stratigraphic interval between the limestone and the base of the Vaqueros formation was measured.
