Skeletal 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.
