Paleontología de las terrazas marinas del valle de Jorós (Fuerteventura, España)

Abstract

Se estudia el contenido paleontológico de 8 terrazas marinas, en su mayoría del Pleistoceno, que afloran a lo largo del valle de Jorós, en Jandía, al Sur de la isla de Fuerteventura: I, II, III, IV, V, VI, VII y XI. Presentan diferentes condiciones de afloramiento, tafonomía, diversidad y abundancia en fósiles de bivalvos, gasterópodos, briozoos, corales, cirrípedos, algas calcáreas, foraminíferos bentónicos y dientes de peces. Las más ricas son II y VII. Se analiza la señal isotópica (C,O) de Ostrea virleti en distintos niveles. δ13CPDB varía entre 1,34 y 1,88‰, y δ18OPDB entre -0,36 y 0,9‰. El valor mínimo referido al Oxígeno se registra en el episodio IV, y probablemente corresponde al mar más cálido. Se aprecia un leve incremento progresivo de 18O en las terrazas V, VI y VII. Se sugieren ambientes sedimentarios muy someros, con temperaturas de la superficie del mar algo más cálidas que las actuales.
