Prosimian vs. Simian skulls
Contrast between prosimian and simian skull bones (after)
One
of the differences between the skulls of prosimians (such as the lemur
at left) and simians (such as the monkey at right) is whether the
frontal bone is fused. In the prosimian, it is unfused; in the simian,
it is fused.
