Occurrence of the “Boreal type” bivalves: inoceramids (represented by the genera: Inoceramus Parkinson, 1819; Retroceramus Koshelkina, 1963 and Anopaea Eichwald, 1861) and buchiids (Buchia Rouillier, 1845) in the Tithonian sections of the Sierra de los Organos and Sierra del Rosario belts, western Cuba, is described. Anopaea and other “Boreal” bivalves probably migrated to the Cuban Jurassic basin over the South American shelf and probably throught Southern Mexico. Their occurrence might reflect cooler temperature in the proto-Caribbean basin caused by oceanic currents and/or upwelling, rather than tectonic transport from Southern Boreal province.
