Abstract

"A new lithostratigraphic unit in the upper Cretaceous of northcentral Venezuela is named and defined as the Escorzonera formation. The age of this formation has been established as Maestrichtian from the occurrence of a number of species of larger foraminifera. Certain interesting foraminifera from the Morro del Faro member of the Guarico formation are also included, since they help to define the age of the large morros of San Juan as Paleocene, contrary to recently expressed opinion that they may be of Cretaceous age. The genus Laffitteina is reported for the first time from the Western Hemisphere."
