The “Naparima rocks” consist of an anticlical that, abutting in a bluff near San Fernando, on the Gulf of Paria, extends across the island almost to the east coast. They also appear on the mainland of Venezuela near the Bay of Cumana. The lowest strata are Cretaceous, and are called, together with the Eocene above them, the “Older Parian.” The “Newer Parian” above is Miocene, and contains lignites and bitumen. Here orbitoides and nummulites are found in a mass of rock projecting into the Gulf of Paria, supposed to be Miocene. In the Western Hemisphere orbitoides are supposed to characterize the Eocene. In the Eastern Hemisphere nummulites are characteristic of the same formation. The deposit that here contains them both lies between other Miocene deposits.
