FIG. 2. — Estimation of skull length for fragmentary specimens of Euthecodon Fourtau, 1920: A, partial mandible of E. cf. brumpti (L 32-203, C 5-7, c. 2.6-2.7 Ma) in dorsal view; B, tooth spacing along the rostra of four complete skulls used to train the regression, plotted as points, with smoothed curves showing how alveolar spacing changes along each snout, with the anteriormost alveoli the greatest distances apart; C, the linear regression equation used to relate that average tooth spacing value (excluding the anteriormost two alveoli) to dorsal skull length, based on the best-fit line through points representing the average tooth spacing of each dentary and maxilla in the four complete skulls. Abbreviations: Ant, anterior; ER, East Rudolf; KNM, National Museums of Kenya; KP, Kanapoi; LT, Lothagam; Pos, posterior. Scale bar: A, 5 cm.
