De verschillende methoden en technieken hebben hun beperkingen.Zo is de koolstof 14-methode niet geschikt voor gesteenten en voor ouderdomsbepalingen ouder dan circa 60.000 jaar.) 13,800,000,000 (13.8 billion) years ago The creation of the universe according to present estimates of "big bang" - "Stephen Hawkings and others...estimate between 18 and 11 billion with 13.8 being the closest estimation".Homo erectus is often referred to as the first cosmopolitan hominin lineage, meaning the first hominin species whose geographic range had expanded beyond a single continental region. erectus are found in Africa, like those of earlier hominins, they have also been identified at fossil sites widely dispersed across Eurasia (Figure 1, Table 1). A partial list of key Homo erectus fossil localities, and some of the key specimens preserved at each.Exact dates are difficult to obtain for many of these localities, so the above dates represent best approximate ranges.

The procedure of radiocarbon dating can be used for remains that are up to 50,000 years old.It is suggested that analysis of sedimentary pyrite from the Belingwe sedimentary basin in Zimbabwe may provide evidence for bacterial reduction at this date.2,500,000,000 to 542,000,000 years ago The Proterozoic Eon: the most recent part of the Precambrian Supereon.With its earliest appearance in the fossil record from localities in the Lake Turkana Basin, Kenya, sometime around two million years ago, H.erectus populations persisted until near the end of the Pleistocene, as evidenced by fossils from Southeast Asia.
