Dating different fossil technique
Until this century, relative dating was the only technique for identifying the age of a truly ancient object.
By examining the object's relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site.
is, as mentioned earlier, the technique of piecing together the informational content of separated outcrops.
When information derived from two outcrops is integrated, the time interval they represent is probably greater than that of each alone.
Though still heavily used, relative dating is now augmented by several modern dating techniques.
Radiocarbon dating involves determining the age of an ancient fossil or specimen by measuring its carbon-14 content.
This grid system enabled them to record the horizontal and vertical positions of the excavated fossils and artefacts.
Precambrian rocks must therefore be correlated by means of precise isotopic dating.Sterkfontein has produced some of the most famous hominid fossils in the world, together with a range of other fossils of animals and plants.The site has a very high concentration of fossils – the highest in the Cradle of Humankind – which, as a whole, has produced more fossils of early hominids than any other site on Earth.Palaeoanthropology is the scientific study of hominid fossils and their cultural material and origins.Sterkfontein is home to one of the world’s longest running palaeontological excavations.
