Short summary
We present the first marine pollen record of the early Pliocene from western equatorial South America. Our reconstruction of the vegetation aims to provide insights into hydrological changes related to tectonic events (Central American Seaway closure, uplift of the Northern Andes). We find stable humid conditions, suggesting a southern location of the Intertropical Convergence Zone. The presence of high montane vegetation indicates an early uplift of the Western Cordillera of the northern Andes.
