dc.description | The coastal region of northeastern Brazil holds one of the most important records of mosasaurids from the Late Cretaceous of South America. Analysis of these discoveries allowed us to create a picture of the composition of the fauna, as well as the diversity and paleobiogeography of these clades. In the region, the mosasaurid fossils are contained in Cenomanian to Maastrichtian geological units of epicontinental marine origin, in the Cotinguiba (Sergipe-Alagoas Basin), Alcântara (São Luís Basin), Itamaracá (Paraíba Basin), Calumbi (Sergipe-Alagoas Basin), and Gramame (Paraíba Basin) formations. Paleogeographic data corroborate that these deposits represent low-latitude equatorial environments. The Brazilian fauna is represented by fourteen taxa from one family (Mosasauridae), two subfamilies (Mosasaurinae: Prognathodontini, Globidensini and Mosasaurini; Plioplatecarpinae: Plioplatecarpini), and some indeterminate mosasaurid specimens. Mosasaurids from the northeastern region of Brazil resemble Late Cretaceous marine reptiles from western Africa (Angola, Congo, and Morocco), suggesting faunal continuity in the seaway that bridged these areas. The study of this marine fauna is crucial to understanding the evolutionary and paleobiogeographic history of the group during the opening of the South Atlantic Ocean. | en-US |
dc.description | La región costera del noreste de Brasil presenta uno de los más importantes registros de mosasaurios del Cretácico Superior de Sudamérica. Un exhaustivo análisis de estos registros se presenta en esta contribución para proveer una nueva perspectiva sobre la composición faunal y la diversidad y paleobiogeografía de estos clados. Los fósiles de mosasaurios en la región se encuentran en unidades geológicas de edad cenomaniana a maastrichtiana de origen marino epicontinental. Particularmente en las formaciones Cotinguiba (cuenca Sergipe-Alagoas), Alcântara (cuenca São Luís), Itamaracá (cuenca Paraíba), Calumbi (cuenca Sergipe-Alagoas) y Gramame (cuenca Paraíba). La evidencia paleogeográfica confirma que estos depósitos representan ambientes ecuatoriales de baja latitud. El registro fósil estudiado incluye catorce tazones de una familia (Mosasauridae), dos subfamilias (Mosasaurinae: Prognathodontini, Globidensini y Mosasaurini; Plioplatecarpinae: Plioplatecarpini), y especímenes indeterminados de mosasaurios. El registro fósil estudiado presenta similitudes con aquél del Cretático Superior del oeste de África (Angola, Congo y Marruecos), lo cual sugiere continuidad faunal a través de la vía marítima que conectó estas regiones. El estudio de esta fauna fósil marina se considera crucial para entender la historia evolutiva y paleobiogeográfica del grupo durante la apertura del océano Atilántico sur. | es-ES |
