Sometimes, archaeologists will date an object by carbon dating another object nearby.This method of dating obviously relies on assumptions about the relationship between the object and the actual tested material.He adds that, although “we know a lot about what the paintings mean”, scientific techniques have not been widely applied to archaeological findings in the region.Many experts had assumed that the black paint used in African pictures was based on manganese compounds and that the rock art would therefore have contained too little carbon to be reliably dated, he says..action_button.action_button:active.action_button:hover.action_button:focus.action_button:hover.action_button:focus .count.action_button:hover .count.action_button:focus .count:before.action_button:hover .count:before.u-margin-left--sm.u-flex.u-flex-auto.u-flex-none.bullet.

Carbon dating, or radiocarbon dating, can be helpful in determining the relative age of an object, but has many limitations.
So obtaining an accurate age depends on the assumption of how much carbon-14 was in the atmosphere at the time the organism died.“We know relatively little about these groups because of the paucity of archaeology.” Rock paintings show that these groups interacted, but, because the paintings were discovered at sites that contain no other artefacts, they have not been reliably dated.“What we’ve been doing previously existed out of time,” says Pearce.When such material does die, the material stops absorbing carbon-14 and the carbon-14 within it begins to decay.Carbon-14 makes up about 1 trillionth of the earth's atmosphere, so these minuscule quantities are what scientists rely upon.
