Figure 5: 3D model of the surface of the malleus (M), incus (I), and stapes (S) reconstructed by the μCT dataset of the embedded specimen in the following orientations: medial (a) and lateral surface (b) of the auditory ossicles with the nutrient foramen on the malleus (blue arrow) and on the incus (red arrows). From the lateral side (c) the not calcified areas can be seen inside the half-transparent malleus (blue arrow) and incus (red arrows).
