Figure 4

Scaling of thigh (orange), shank (blue), tarsometatarsal segment (green), and digit (yellow) masses for the entire neognath sample. The upper plot A depicts scaling relationships relative to body mass; the lower plot B depicts scaling relationships relative to hindlimb length. In addition to the slope and confidence limits provided in the plots, the results of F-tests testing for departures from isometry are listed in TableĀ 2.
