Age of the "Modelo" in Haskell Canyon, easternmost Ventura Basin, California


White, Robert C. (1947) Age of the "Modelo" in Haskell Canyon, easternmost Ventura Basin, California. Master's thesis, California Institute of Technology.


An invertebrate fauna from the "Modelo" formation in Haskell Canyon, easternmost portion of the Ventura Basin California is listed and discussed. An Upper Miocene age, Neroly stage, is assigned to the fauna on the basis of Astrodapsis cf. tumidus, Astrodapsis of. whitneyi, Pecten (Lyropecten) crassicardo, Turritella carrisaensis, Pecten (Aequipecten) discus, and Ostrea titan s.s. The Haskell Canyon fauna is correlated with the Santa Margarita s.s. and the Neroly formation of the San Pablo Group, and is shown to be older than the Jacalitos and the Elmere Canyon faunas. A new species of Anadara is described.
