This approach included dating the fossils directly, as well as dating the sediments that the fossils are buried in and the flowstones (calcium carbonate deposits, such as stalagmites) that cover the fossils and surrounding sediment in the chamber.
We can determine how old some fossils and geologic materials (such as flowstone) are using radiometric dating.
This evidence prompted some paleoanthropologists to describe ER 1470 as one of the most ancient undoubted representatives of the genus KNM-ER 1805.Villmoare holding a replica of the Ledi-Geraru jawbone., a new species of hominin (human ancestor), from the Rising Star Cave in The Cradle of Humankind World Heritage Site, South Africa., they described the increased cranial capacity and comparatively smaller molar and premolar teeth of the fossils, a humanlike foot, and hand bones that suggested an ability to manipulate objects with precision—hence the species name .
Pieces of another thin-walled cranium along with upper and lower jaws and teeth came to light in 1963.Despite its anomalies, ER 1805 is often discussed along with other specimens grouped as A more-valuable discovery was reported from Olduvai Gorge in 1986.
