Figure 13.

(A) Photograph (left) and line drawing (right) of left fibula of Megapnosaurus rhodesiensis (QG 811) in medial view possessing the immature character state for character 30. (B) Photograph (left) and line drawing (right) of left fibula of M. rhodesiensis (QG 813) in medial view possessing the mature character state for character 30. (C) The mature state for the fibular scar (character 30) is mostly present in larger individuals, and the immature state in some of the smallest individuals, but the small fibular sample size and difficulty in scoring articulated specimens make OSA difficult to perform on this character, and to determine how variable this character is with respect to body size. The y‐axis is dimensionless. Scale bar: 1 cm.
