Where: Falcon, Venezuela (10.4° N, 70.1° W: paleocoordinates 9.6° N, 66.7° W)
• coordinate stated in text
• outcrop-level geographic resolution
When: Castillo Formation, Burdigalian (20.4 - 16.0 Ma)
• The Castillo Formation has formely been regarded as late Oligocene in age (Wheeler, 1960), but more recent workers, including this reference regard it to be early Miocene. The Castillo Formation unconformably overlies Eocene rocks of the Misoa Formation, although neither upper or lower contacts can be viewed at the collection's section. The section comprises 87 m of clayey marls interbedded with numerous thin (<1 m) hardground units. The strata are underlain and overlain by sandstones, and the upper 15 m are gypsiferous. Most fossils were collected near the base of the exposures. The turtle skull was collected from the top, however.
