Figure 12: Norma occipitalis (posterior view) of the cranium of Olduvai 

 hominid 5, the type specimen of Australopithecus boisei. Its artificial 

 endocast made by me, assisted by A. R. Hughes and T. W. Kaufman, 

 is shown in Figure 3. The volume of the total endocast has been 

 determined as 530 c.c. 



which is present as far forward as the posterior half or more of the 

 hypophyseal fossa on its dorsum, whilst ventrally a substantial part of the 

 vomer articulates with the sphenoid rostrum. In higher Primates the medial 

 aspect of the temporal poles abuts close to the body of the sphenoid. 



Available for comparison was a large collection of plaster endocranial 

 casts of gorilla, chimpanzee, orangutan, cercopithecoids, Homo erectus and 

 other fossil hominines, and modern man, as well as australopithecine 

 natural endocasts, and plaster endocasts of those australopithecines for 

 which no natural endocast had formed or been found. 



Under such circumstances, it is felt that the plaster endocast of Old. 

 Horn. 5 cannot be far from the mark and cannot deviate volumetrically
