Table 1. Measurements (in mm) of Hyaenodon weilini from Lanzhou Basin. Measurements for H. gigas are estimated from a combination of Dashzeveg’s measurements and his figure 12 (1985), because he apparently adopted an unconventional system of measuring the dimensions of the roots at the points of contact with the maxilla.
