Figure 3. Measurements conducted for quantitative analyses.

Figure 3

A, measurements indicated on left femur of Alligator mississippiensis (American alligator) in medial view: CC, craniocaudal; GL, greatest length; ML, mediolateral. B, GL measurement for avian specimens indicated on left femur of Struthio camelus (ostrich) in cranial view. GL in birds equals the length from the distal condyles to trochanteric shelf (a) plus the length from the same point on the trochanteric shelf to the medial end of the femoral head (b). C, Segmental measurements and joint angles used from non-avian dinosaur speed estimates (adapted from Gatesy et al. [55]).
