DATA SUMMARY

365 lines of 7 columns

dataset of age ranges given in each source dataset (Utescher and Pound only; see SI) for paleoclimatic records (mean annual temperatures and/or mean annual precipitation as uploaded in Data_Paleoclimate_Regions), and the stratigraphic stages allocated in our datasets (see Data_GenusOccurrence.txt).

Source datasets:

Pound, M. J., Haywood, A. M., Salzmann, U. & Riding, J. B. 2012. Global vegetation dynamics and latitudinal temperature gradients during the Mid to Late Miocene (15.97–5.33 Ma). Earth-Sciences Reviews 112, 1-22.

Utescher, T. Bruch, A. A., Erdei, B., François, L., Ivanov, D., et al. 2014. The Coexistence Approach—theoretical background and practical considerations of using plant fossils for climate quantification. Paleogeography Paleoclimatology Paleoecology 410, 58-73.

DATA EXPLANATIONS: column names and content

- Source: the short reference for the source dataset
- Loc_IDs: the unique location IDs for the locations with the given age range (for Pound data: entries in the literature column, separated by " AND "; for Utescher data, composite entries separated by " ; ", where each composite entry was generated from the Location_number, Literature, and Pangaea_DOI, separated by "_")
- Max_Age: the oldest age (in million years ago) for the data point as given in the source dataset
- Min_age: the youngest age (in million years ago) for the data point as given in the source dataset
- OriginalTimeslice: the original stratigraphic stage allocated in the source dataset (Pound data only)
- AutomaticStage: the automatically allocated stratigraphic stage(s) for the data point, separated by " AND "
- BestStage: the best allocated stratigraphic stage(s) for the data point, separated by " AND "

DATA ORIGINS AND PROCESSING

We assigned global time bins (i.e. stratigraphic stages) as described in our paper: briefly, we assigned stratigraphic stages with automatic allocation based on the min and max age given in the original data sources, and with manual allocation of the best stratigraphic stage based on chronology information and original allocations in the data sources. See Metadata_Paleoclimate_Regions.txt and SI for details.
