Quantification of the mineralization of chicken ossicles. Data were derived from the interior region of each ossicle, as viewed
in cross-section (Figure 7

: C/O and Ca/P ratios in chicken ossicles during development. Crosshatch gaps (//) are shown between the E21 and 1 week ages,
and between the older ages to emphasize that the time scales in these 3 regions are not a linear continuous line.
