Figure 7. Representative FESEM EDS mapping analysis of chicken ossicles. Surface (A, G) and cross sectional (D, J) secondary electron images and corresponding calcium (B, E, H, and K) and phosphorus (C, F, I, and L) EDS maps are presented from two different developmental time periods: E14 (A, B, C, D, E, and F) and E18 (G, H, I, J, K, and L). In maps, white pixels indicate both the intensity (quantity) and location of the given element.
