Diversification dynamics of vegetation during the Cenozoic in the Neotropics: A palynological perspective from Colombia

The Neotropics maintains the highest biodiversity of the planet, exerts control in global climate and play an important role in the dynamics of our planet. Researches from a wide range of disciplines are very interested in understanding how diversity in the Neotropics was produced and how it is maintained through deep time. Despite important advances in our understanding of the origin and diversification of Neotropical biota, we still do not have a clear idea about the patterns of diversification through geological time. This presents a significant knowledge-gap that needs to be filled. Fossils are necessary to understand the history of the Neotropical biota. From the perspective of plants, palynology represents the best proxy to study the macroevolution of vegetation. Pollen and spores fossilize readily, they are produced in large amounts, are found in a widely variety of sedimentary environments and they have high stratigraphic resolution. In this work, we used a compilation of palyno..., , , # Diversification dynamics of vegetation during the Cenozoic in the Neotropics: a palynological perspective from Colombia [https://doi.org/10.5061/dryad.rbnzs7hn9](https://doi.org/10.5061/dryad.rbnzs7hn9) ## Description of the data and file structure ### Files and variables #### File: Supplementary\_Files.xls 1. **SF-1**:  mean standing diversity estimated from the complete composite section assuming range-through and using only species with stratigraphic ranges below a threshold duration.   Age_bin: age in millions of years   Max duration=70: diversity estimated for each Age bin when dataset includes only taxa with long stratigraphic ranges (spanning 70 Ma)   Max duration=10: diversity estimated for each Age bin when dataset includes only taxa with relatively short stratigraphic ranges (spanning less than 10 Ma   Max duration=1: diversity estimated for each Age bin when dataset includes only taxa with relatively short stratigraphic ranges (spanning less than 1 ...
