Preliminary data on a new Albian flora from the Valle del Rيo Martيn, Teruel, Spain

A newly discovered plant fossil assemblage in the Albian Escucha Formation, located at Valle del Rيo Martيn (Teruel, Spain), shows similarities with the classic early Cretaceous flora of the Potomac Group in the USA. This is the first time that a flora of this age and composition has been found in Spain. It comprises representatives of ferns, Ginkgoales, Bennettitales, Caytoniales, conifers and angiosperms and suggests a possible mixing of the European and Potomac provinces in the early Cretaceous within the Iberian Peninsula, in a subtropical, semi-arid climate.
