From: Occipital condyle width (OCW) is a highly accurate predictor of body mass in therian mammals
Scatterplot of natural log of OCW versus natural log of body mass, showing the best fit (natural log OCW raised to the 2/3 power) regression line for all species and the non-linear distribution of the data. Linear regression is in red and 2/3 power regression is in blue. Dashed lines represent 95% prediction intervals. Most of the species located above the upper bounds of the prediction interval are lagomorphs (see Fig. 7)
