Fig. 5. Variation of probability with respect to the aspect ratio predictor variable (one of the two variables included in analysis M2). This plot shows that at aspect ratios of approximately 2.5–3.5, the probabilities of predicting any of the four possible colour categories are similar, and none are very likely. Several samples in Wulong bohaiensis (DNHM D2933) had an aspect ratio within this range.
