FIGURE 2. 3D surface models of cf. Tamias urialis in occlusal views. A) WIMF/A 4743 right M1/2 (mirror-imaged); B) WIMF/A 4749 left m1/2. Note: Mesial towards the left and distal towards the right in all panels.
FIGURE 3. Scatterplot of molar size (sq. root of width*length) vs. shape (max. width/length) of Siwalik Tamias specimens. A) M1/M2; B) m1/m2. See Table 1 for data used in the plots. Note that minimum, mean and maximum values were used to approximate ranges of variation in large samples of Tamias anatoliensis, T. urialis, and T. atsali.
