Fig. 6. (A) Spatial distribution of bone volume (in mm3) during
development along the rostral-caudal axis of lordotic vertebral centra (red)
in comparison with normal vertebral centra (blue). `Position on centrum'
indicates position (in percentage of centrum length) along the rostral-caudal
axis of the vertebral centrum. `Total length' indicates total length of the
specimens and thus developmental stage. Blue and red solid lines indicate the
actual vertebrae (normal and lordotic, respectively) measured. (B) Difference
of mean bone volume between lordotic and normal vertebrae as a function of
position along the vertebral centrum. Dark green indicates the region where
the 95% confidence intervals of lordotic and normal vertebrae do not
overlap.
