Data from: Body size and extinction risk in terrestrial mammals above the species level

Fossil Occurrence DataFossil occurrence data compiled from the MIOMAP and FAUNMAP databases (http://www.ucmp.berkeley.edu/neomap/). Each locality is identified by the combination of database name (“MM” for MIOMAP, “FM” for FAUNMAP), Machine Number, and Analysis Unit. Included in the data table are: Max_age, maximum age of locality in million years; Min_age, minimum age of locality in million years; Genus_accepted, standardized genus designation; Species_accepted, standardized species designation; Genus_NEOMAP, genus designation in MIOMAP/FAUNMAP; Species_NEOMAP, species designation in MIOMAP/FAUNMAP; ID_conf_NEOMAP, level of confidence in the original species identification.Dryad_Tomiya Fossil Occurrence Data.csvCladogramComposite cladogram for 276 North American fossil genera. See article and Online Appendix B for complete sources of information.Dryad_Tomiya Cladogram.nexBody Mass DataSkeletal measurements and estimated body masses of 901 taxa. Refer to Online Appendix B for additional information. Included in the data table are: LnMass, natural-log transformed body mass (originally in grams); m1L, anteroposterior length of the lower first molar; m1W, transverse width of the lower first molar; otherL, anteroposterior length of a skeletal element other than m1 (reported under Remarks); otherW, transverse width of a skeletal element other than m1 (reported under Remarks). See Body Mass References for a list of literature sources of measurements. Measurement data in the Paleobiology Database were obtained from: http://paleodb.org/cgi-bin/bridge.pl.Dryad_Tomiya Body Mass Data.csvBody Mass ReferencesLiterature sources of skeletal measurements reported in Body Mass Data.Dryad_Tomiya Body Mass References.pdfGeneric DataGeneric data for phylogenetic comparative analyses. Included in the data table are: Group1/2, taxonomic affiliation above the genus level; Occurrences, number of genus-level occurrences in North America; T_FAD, observed first appearance date; T_LAD, observed last appearance date; T_FAD50, sampling-adjusted first appearance date; T_LAD, sampling-adjusted last appearance date; LnMass, natural-log transformed estimated body mass (originally in grams); LnIBIL, natural-log transformed expected inter-birth interval length (originally in days).Dryad_Tomiya Generic Data.csv
