DATA EXPLANATIONS: column names and content

- Continent (in Data_Regions this column comes after the ContinBin... columns): the continent (Europe or North America)
- Region (in Data_Regions only): the region (6 different values)
- GlobalTimeBins: the global stratigraphic stage (NA if data are for a land mammal age or unit)
- ContinentalBins: the  continent-specific land mammal age or unit (NA if data are for a stratigraphic stage)
- NumLocs: the number of mammalian locations
- NumGenera: the number of mammalian genera (raw count data)
- GlobalBinStart, GlobalBinEnd, GlobalBinCenter: the start, end, and center date of global stratigraphic stages (million years ago)
- ContinBinStart, ContinBinEnd, ContinBinCenter: the start, end, and center date of continent-specific land mammal ages or units (million years ago)
- S.chao1: the diversity estimate with the Chao1 estimator
- se.chao1: the standard error of the diversity estimate with the Chao1 estimator
- S.ACE: the diversity estimate with the ACE estimator
- se.ACE: the standard error of the diversity estimate with the ACE estimator
- chao: the diversity estimate with the Chao estimator
- chao.se: the standard error of the diversity estimate with the Chao estimator
- jack1: the diversity estimate with the first-order Jackknife estimator
- jack1.se: the standard error of the diversity estimate with the first-order Jackknife estimator
- jack2: the diversity estimate with the second-order Jackknife estimator
- boot: the diversity estimate with bootstrapping
- boot.se: the standard error of the diversity estimate with bootstrapping
- Area: the area (minimum convex hull around mammalian locations)
- Area2: the area adjusted for tectonic extension of Western North America
- NPP_AutoPlants_NumCells: the number of grid cells with NPP estimates, based on automatic stage allocation for paleobotanical data
- NPP_AutoPlants_meanhdr: the mean NPP estimate across grid cells based on automatic stage allocation and a simple average of the highest-density values of paleoclimatic estimates
- NPP_AutoPlants_sehdr: the standard error of the mean NPP estimate
- NPP_AutoPlants_meanhdrwght50: the mean NPP estimate across grid cells based on automatic stage allocation and the weighted mean of the highest-density values of paleoclimatic estimates (weighted by the inverse length of 50% credibility intervals)
- NPP_AutoPlants_mean50low, NPP_AutoPlants_mean50high: simple mean across grid cells of the lower and upper bounds of the 50% credibility interval for NPP values, based on automatic stage allocation
- NPP_AutoPlants_meanmin, NPP_AutoPlants_meanmax: simple mean across grid cells of the minimum and maximum NPP values, based on automatic stage allocation
- NPP_AutoPlants_meanminwght50, NPP_AutoPlants_meanmaxwght50: weighted mean across grid cells of the minimum and maximum NPP value, based on automatic stage allocation and weighted by the inverse length of 50% credibility intervals
- NPP_BestPlants_ ...: same columns as above, but based on stratigraphic stage allocation for paleobotanical data
