(Instituto de Geologia, Universidad Nacional Autónoma de México, 2015-12) Távora, Vladimir de Araújo; Dias, Jaime Joaquim; Santos, Claude Luiz de Aguilar
This work deals with the systematic study of the corals collected in the Jandaíra Formation, Turonian-Campanian of the Rio Grande do Norte state, Brazil. The specimens were recognized as Actinastrea decaturensis (Vaughan, 1919), A. guadalupae (Roemer, 1849), Stephanocoenia guadalupae Wells, 1932, Madracis johnwellsi Frost and Langenheim, 1974, Isastrea whitneyi Wells, 1932, Paracycloseris effrenatus Filkorn and Pantoja-Alor, 2009 and Orbicella travisensis Wells, 1932, as well as Isastrea sp. and two doubtful species, Turbinolia (Turbinolia)? insignifica Vaughan, 1900 and Placotrochus? texanus (Vaughan, 1903). The majority of these species occurs in the Aptian-Albian of USA and Mexico, as well as the Lower Tertiary of Central America and north of South America. This fauna is the westernmost hermatypic assemblage of the Turonian scleractinian and has affinities with others shallow marine Cretaceous units within USA and Mexico
