| Description | The changes that primate skulls have undergone are of utmost importance regarding teeth, volume of braincase and position of the foramen magnum. Should the foramen magnum face directly downward, the head would have been carried over the spine, proving erectness and bipedalism. The knowledge of the half-life of certain radio-active isotopes is the key for calculating the age of a fossil. Changes of any part of an animal becoming fossilized are very slight. Chances of finding it are so much more slight. In Oligocene times the anthropoid primates were successful tree-dwellers. The Fayum was heavily wooded, a fine place for proto-monkeys to live - and evolve. Evolve they did, for the Fayum contains a uniquely rich deposit of primate fossils. Van belong is die veranderinge wat die primaatskedels ondergaan het, veral ten opsigte van die tande, volume van die breinkas en die verskuiwing van die foramen magnum. Die na onder gerigtheid van die foramen magnum dui op ’n skedel bo-op en nie vooraan die ruggraat nie en dui dus op bipedalisme. Melodes van tydsberekening is noodsaaklik en die reeds bekende halfleeftye van bepaalde isotope is onontbeerlik vir sinvolle ouderdomsbepaling. Omrede alle faktore gunstig moet wees, is die uiters belangrike fossilering ’n baie seldsame verskynsel. Vir behoorlike spoorsny, moet sover teruggegaan word as die begin van die Oligoseenepog. Dit was die tyd van die opkoms van die antropoiede primate, wat as suksesvolle boombewoners in verskeidenheid ontplooi het. | |
