Measurements of basal skull length (BSL) and maximum skull width at the zygoma (SWZ); and estimates of body mass(BoM), canine bite force (CBS), and bite force quotient (BFQ), for 39 taxa of recent and fossil mammals.(Measurements and calculations were taken from prepared skulls. Methods for body mass estimations given in ElectronicAppendix, section A. Fossil taxa indicated with †.) Figure 2. Basal skull length (BSL) plotted against body mass (BoM).
