Characters: F, femur length; FL, humerus plus radioulna lengths; H, humerus length; HL, femur plus tibiofibula length; RU, radioulna length, TF, tibiofibula length. All measurements given in mm. Because of the large number of statistical comparisons, alpha was set at 0.005 to reduce the chance of a type I error.
