Figure 7. Linear osteoderm measurements used in allometric and morphometric analyses.

Schematic drawing illustrating the four linear measurements obtained for representative osteoderms with (A) well-developed spines, (B) moderately developed spine, and (C) medial ridge. AP-L, anteroposterior length; T-W, transverse width; H, height; SL, spine length. AP-L, T-W, and H are mutually orthogonal and rectilinear.
