The Castillo Formation is a Oligocene to Miocene geologic formation in Venezuela. The formation unconformably overlies the Matatere, El Paují and Jarillal Formations. The Castillo Formation is overlain by Quaternary alluvium and in places by the Capadare Formation. In the formation, fossils of the giant sloth Baraguatherium takumara, the turtle Chelus colombiana and the pelican-like Pelagornis sp. have been found. The pelican-like fossil is the oldest of South America.
