Natural history. 166 ANNALS OF THE SOUTH AFRICAN MUSEUM Age in the Skull of the Tapinocephalidae In the Moschopid, Moschops and the Struthiocephalid, Struthiocephalus, where a fair number of skulls is available for comparative study, there is evidence (somewhat obscured by the possibility of sexual dimorphism) that with increasing age the pachyostosis is intensified. But there is also evidence that the increased pachyostosis during the lifetime of the individual is paralleled by a very similar increased pachyostosis

In the Tapinocephalids we still have insufficient material to supply the necessary evidence on these matters. Fig. 15. Kerotocephalus moloch.
