This dataset presents global revised age models for taxonomically harmonized fossil pollen records. The age-depth models were established from mostly Intcal20-calibrated radiocarbon datings with a predefined parameter setting. 986 sites are located in North America, 1011 sites in Europe, 470 sites in Asia. On the Southern Hemisphere, there are 145 sites in South America, 52 in Africa and 24 in the Indopacific. Datings, mostly ¹⁴C, were retrieved from Neotoma ([https://www.neotomadb.org/]), with additional data from Cao et al. (2019; [https://doi.pangaea.de/10.1594/PANGAEA.898616]) and Cao et al. (2014, [https://doi.org/10.1016/j.revpalbo.2014.08.007]). The related age records were revised by applying a similar approach i.e. using the Bayesian age-depth modelling routine in R-BACON software. We complement the data publication by providing the source information on the references (most data are related to Neotoma) as a table linked to each Dataset ID, The data set and site IDs are from Neotoma if the data sets are derived from the Neotoma repository. In case of our own data collection efforts Cao et al. (2019) and Cao et al. (2014), we used the already published PANGAEA event names in case they are related to the data or created own site names with referencing to geographical regions similar to the Neotoma data naming principle.
