Figure 23: Two views of the artificial endocast of Olduvai hominid 16, 

 made by Mr. R. J. Clarke from my reconstruction of the calvaria. The 

 volume of the partial endocast is 410.6 c.c; the estimated volume of 

 the entire endocast of this adolescent is 620 c.c. 



eminence was partly intact and could be reconstructed in the defective area. 

 Thus, the lower margin of the cerebral fossae of the occipital is clear. Ante- 

 riorly, the endocranial aspect of the frontal squame is present as far as the 

 front edge of the floor of the anterior cranial fossa.
