Scleractinia Corals of the Jandaíra Formation (Turonian- Campanian), Rio Grande do Norte state, Brazil
Contenido principal del artículo
Resumen
Varias especies de corales colectadas en estratos del Cretácico Superior (Turoniano-Campaniano), correspondientes a la Formación Jandaíra en el estado de Rio Grande do Norte, Brasil fueron identificadas y descritas en este trabajo. Esta fauna está representada por Actinastrea decaturensis (Vaughan, 1919), A. guadalupae (Roemer, 1849), Stephanocoenia guadalupae Wells, 1932, Madracis johnwellsi Frost y Langenheim, 1974, Isastrea whitneyi Wells, 1932, Paracycloseris effrenatus Filkorn y Pantoja-Alor, 2009 y Orbicella travisensis Wells, 1932, así como Isastrea sp. y dos especies dudosas: Turbinolia (Turbinolia)? insignifica Vaughan, 1900 y Placotrochus? texanus (Vaughan, 1903). La mayoría de las especies se registran en el Aptiano-Albiano de Estados Unidos y México, así como con el Terciario Inferior de América Central y norte de Sudamérica. Esta fauna es la asociación más occidental del conjunto hermatípico de escleractineos Turonianos y tiene afinidades con otras unidades marinas poco profundas del Cretácico de Estados Unidos y México.
