4.8 Diadectes sp.

This is the cast of a skull of a very close relative of the amniotes. Diadectomorphs lived during the Late Carboniferous and Permian.



Make sure you can identify the main openings in the skull. Notice that there are no openings in the temporal region (the area immediately behind the eye). Compare this temporal  area with its equivalent in one of the true amniotes, such as Dimetrodon [seen in Chapter 1] or the procolophonids).
