Functional least squares regression was used to fit the allometric equation, y = bx k , to data on head‐body lengths and body weights for 123 species of mammals. These measurements were found to be highly correlated and to scale isometrically. The scaling of M 1 area with head‐body length was investigated for 288 species of terrestrial mammals. A method was described for estimating the body size of extinct mammals from M 1 area and the tooth size‐body size relationships discovered among contemporary forms.
