TL;DR: It is contended that a uniquely Panamanian Eocene detrital zircon fingerprint is pronounced in middle Miocene fluvial and shallow marine strata cropping out in the northern Andes but is absent in underlying lower Miocene and Oligocene strata; the Central American Seaway had vanished by that time.

TL;DR: The Tumaco basin is a Colombian Caribbean Oceanic Plateau sliver docked with Santonian-Campanian island arcs that was incorporated into the Colombian Pacific forearc during the Paleocene to Eocene as discussed by the authors.

TL;DR: In this article, the authors carried out field mapping, palynological dating, sedimentary, stratigraphic and provenance analyses in Campanian to lower Eocene units exposed in the northern Eastern Cordillera of Colombia (Cocuy region) and compare the results with coeval succession in adjacent basins.

TL;DR: In this article, a contribution integrating new U/Pb zircon ages, heavy mineral analyses and biostratigraphic constraints from the Neogene sedimentary record of the fore-arc and intra-arc basins and volcano-plutonic rocks of southwestern Colombia was made to reconstruct these orogenic processes.

TL;DR: The overall biogeographic pattern of Cyclusphaera is similar to that of Podocarpaceae, one of the most persistent gymnosperm families in the tropics, which could be related to the increase in aridity and expansion of savanna habitats in the northern tropics of South America during the Neogene.
