Short summary
We present a review of chronological dating from ca. 1100 fossil pollen records in Central and South America. Additionally, a temporal quality assessment is implemented on 292 records from northwest South America, which include recalibrating 234 age models. This method evaluates uncertainties for inferred sample ages and chronologies. Important time windows on centennial-millennial climate variability are discussed for sample resolution (estimated years/sample) and temporal uncertainty.
