The Jagua Formation is a Late Jurassic (middle to late Oxfordian[1]) geologic formation in the Sierra de los Órganos and Sierra del Rosario mountains ranges in Pinar del Río Province, western Cuba. Plesiosaur, pliosaur, pterosaur, metriorhynchid, and turtle remains are among the fossils that have been recovered from its strata. The lithology of the 60 metre thick Jagua Vieja Member consists of black shales and horizontally laminated marly micritic to biomicritic limestones. The latter contains calcareous concretions which the fossils are found in.[2]
