The author finds it confusing that in the first of the two paragraphs quoted above the peculiar lack of a post-temporal foramen in this specimen was discussed at length, whilst in the second paragraph the peculiar course of the passage of this foramen was noted. It would appear that, although the openings of the post-temporal foramen could not be located, it was postulated that it opened anteriorly at the medial end of the 'small, shallow excavation' and posteriorly in the floor of the fossa bordering the foramen magnum. If this were the case, then the course of the canal's passage would be different from the direction it assumes in Diademodon. Close examination of the back of this cranium revealed the presence of a matrix-plugged post-temporal foramen on the right side. The matrix that filled the foramen was carefully removed, and the foramen opens anteriorly where Brink (1965) suspected that it might. However, the posterior opening is con- siderably lateral to and above the level of the floor of the fossa where he postulated its exit to be (Fig. 8). This is the position normally occupied by this foramen in Diademodon, and it follows a nearly straight sagittal course as in Diademodon. In a recent illustration of the occipital view of this specimen, Brink (1979: 44) indicated post-temporal foramina, and these are located in correct anatom- ical position, but an explanation of this new interpretation was not Please note that these images are extracted from scanned pag
