Bioestratigrafía del parche arrecifal de la Quebrada Brazo Seco, Plio-Pleistoceno, Limón, Costa Rica

A Plo-Pleistocene patch reef in the Talamanca Range-La Amistad Reserves, Costa Rica, reveals interrupted coral growth due to rapid sedimentation or uplifting. The study describes fossil content—including mollusks, corals, bryozoans, arthropods, and ichnofossils—from the Río Banano Formation, indicating a shallow marine environment with patch reefs. Overlying conglomerates of the Suretka Formation suggest fan delta deposits linked to the uplifting of the Talamanca Range. The research combines outcrop analysis and fossil data to reconstruct depositional conditions, providing insights into the geological history of this UNESCO World Heritage Site.
