| Description | Relative age determination was carried out on the skulls of 261 chacma baboons (Papio ursinus), 117 from the Loskopdam Nature Reserve and 144 from the Messina district in the Northern Transvaal. Seven age groups were distinguished, of which classes I-IV were based on the eruption and displacement of milk and permanent teeth. Adults with a complete set of permanent dentition were subdivided into three additional classes (V- VII), mainly on the basis of the degree of molar attrition. For comparative purposes the pattern of maturation of craniometric parameters which reflect the general size and shape of the skull, as well as the degree of closure of ectocranial sutures, were treated on the same basis. From this it is apparent that a most reliable estimate of relative age can be obtained by using all the above-mentioned criteria. Relatiewe ouderdomsbepaling is op die skedels van 261 Kaapse bobbejane (Papio ursinus), 117 afkomstig van die Loskopdamnatuurreservaat en 144 van die Messinadistrik in Noord-Transvaal, uitgevoer. Sewe ouderdomsgroepe is onderskei, waarvan klasse I-IV op die deurbraak en verplasing van die melk- en permanente tande gebaseer is. Volwassenes met ’n volledige stel permanente tande is veral op grond van die mate van slytasie van die molares in drie verdere klasse (V- VII) onderverdeel. Vir vergelykingsdoeleindes is die patroon van veroudering van kraniometriese parameters wat die algemene grootte en vorm van die skedel weerspieël, sowel as die mate van verbening van ektokraniale nate op dieselfde basis verwerk. Hieruit blyk dat hoogs betroubare aanduidings van relatiewe ouderdom deur middel van al bogenoemde kriteria verkry kan word. | |
