WThe Baitoa Formation is a geologic formation in Dominican Republic. The formation consists of siltstones and limestones deposited in a shallow marine to reef environment. The formation, unconformably overlying the Tabera Formation and unconformably overlain by the Cercado Formation, preserves bivalve, gastropod, echinoid and coral fossils dating back to the Burdigalian to Langhian period.
WThe Cercado Formation is a geologic group in Dominican Republic. The formation comprises siltstones, limestones, claystones, sandstones and conglomerates deposited in a shallow marine to reef environment. The Cercado Formation, unconformably overlying the Baitoa Formation, preserves bivalve, gastropod, decapod and coral fossils dating back to the Late Miocene to Early Pliocene period.
WThe Cerros de Sal Formation is a geologic formation in the southern Dominican Republic. The coastal claystone preserves coral fossils dating back to the Late Miocene period.
WThe El Mamey Formation is a geologic formation in the Dominican Republic. The formation consists of shales and sandstones interspersed with a conglomerate of well-rounded pebbles, deposited in a fluvio-deltaic environment. El Mamey Formation is one of the formations containing Dominican amber and preserves fossils dating back to the Burdigalian to Langhian period.
WThe La Toca Formation is a geologic formation in the northern and eastern part of the Dominican Republic. The formation, predominantly an alternating sequence of marls and turbiditic sandstones, breccias and conglomerates, is renowned for the preservation of insects and other arthropods in amber, known as Dominican amber. The formation is dated to the Burdigalian to Langhian stages of the Miocene period.
WThe Mao Formation is a geologic formation in the northwestern Dominican Republic. The reefal limestone and siltstone formation preserves bivalve, gastropod, echinoid and coral fossils dating back to the Pliocene period.
WThe Nivaje Shale is a geologic group in Dominican Republic. It preserves coral fossils dating back to the Miocene period.
WThe Río Gurabo Formation is a geologic formation in the northwestern Dominican Republic. The reefal limestone preserves bivalve, gastropod and coral fossils dating back to the Messinian to Zanclean period.
WThe Río Hatillo Formation is a geologic formation in Dominican Republic. It preserves bivalve, echinoid, gastropod and ammonite fossils dating back to the Early Albian period.
WThe Tabera Formation is a geologic formation in Dominican Republic. The shallow marine limestone preserves gastropod and coral fossils dating back to the Late Oligocene period.
WThe Yanigua Formation is a geologic formation in Dominican Republic. The lagoonal claystones and marls preserve fossils dating back to the Miocene period. The formation hosts Dominican amber.
WThe Yaque Group is a geologic group in the southern Dominican Republic. The shallow marine limestone preserves coral fossils dating back to the Late Miocene to Early Pliocene period.
