FIGURE 11.

Summary of section stacking of tibiae demonstrating the obliteration of the inner cortex (early ontogeny) via processes of secondary bone remodeling. Schematics highlight cortical bone (solid gray), extent of medullary cavity and/or secondary osteon development (dotted white), and growth marks (solid black line). Circumferences refer to the extent of the medullary cavity and/or extensive inner cortex secondary remodeling (MC/SR), growth mark (GM), and outer/periosteal circumference (outer). The imaged thin sections were retrodeformed, except for ROM 67793 for which most of the periosteal margin and cortical bone remained intact
