Patagonia-Antarctic Peninsula: Clues to a Lost Connection

ENGLISH: This project will allow the adjustment of the ages of the Paleogene marine transgressions between 65 and 23 My in southern Patagonia and the northern Antarctic Peninsula, therefore providing a more precise temporal framework for hypotheses about paleoenvironmental changes and evolutionary processes recorded in the marine ecosystems of these regions during this time. Consequently, more precise paleoenvironmental and paleogeographic reconstructions are expected, in addition to a better constrained biostratigraphy and more accurate regional and intercontinental correlations.

SPANISH: RESUMEN Mediante este proyecto se ajustar�n, por medios geoqu�micos y paleontol�gicos, las edades de las transgresiones marinas del Pale�geno -entre los 65 y 23 millones de a�os antes del presente - en el sur de Patagonia y en el norte de la Pen�nsula Ant�rtica. Esto permitir� ubicar, en un marco temporal m�s preciso, las modificaciones paleoambientales y los procesos evolutivos registrados en los ecositemas marinos de estas regiones durante el intervalo considerado.
