DATA EXPLANATIONS: column names and content

- Continent (in Data_AnalysesRegions this column comes after the GlobalTimeBins column): the continent (Europe or North America)
- Region (in Data_AnalysesRegions only): the region (3 focal regions only)
- GlobalTimeBins: the global stratigraphic stage
- GlobalBinLength: the duration of the stratigraphic stage
- NumLocs: the number of mammalian locations
- jack1: the diversity estimate with the first-order Jackknife estimator
- jack1_stderr: the standard error of the diversity estimate with the first-order Jackknife estimator
- jack1_adj_extinction: the diversity estimate jack1 for fossil stages, and the diversity adjusted for Pleistocene and Holocene extinctions for the present day
- Area: the area (minimum convex hull around mammalian locations)
- Area2: the area adjusted for tectonic extension of Western North America
- NPP_NumCells: the number of grid cells with NPP estimates, based on stratigraphic stage allocation for paleobotanical data
- NPP_meanhdrwght50: the mean NPP estimate across grid cells based on stratigraphic stage allocation and the weighted mean of the highest-density values of paleoclimatic estimates (weighted by the inverse length of 50% credibility intervals)
- NPP_hdrstderr: the standard error of the man NPP estimate
- NPP_adj_HANPP: the mean weighted NPP estimate for fossil stages, and the present-day NPP adjusted for human appropriation
- Area_lg: log-transformed Area
- Area2_lg: log-transformed Area2
- Time_lg: log-transformed GlobalBinLength
- NPP_meanhdrwght50_lg: log-transformed NPP_meanhdrwght50
- NPP_adj_lg: log-transformed NPP_adj_HANPP
- BestModelResiduals: the residuals of the best diversity-productivity-model (Table 1)
