Anthropologists in Kenya have discovered a 13 million year-old baby ape skull that reveals what the common ancestor of all living humans and apes would have looked like.The lemon-sized skull was discovered in 2014 at Napudet, a dig site west of Lake Turkana in northern Kenya, according to the study published in , derives from the Turkana word for ancestor.Carbon-14 cannot be used to date biological artifacts of organisms that did not get their carbon dioxide from the air.This rules out carbon dating for most aquatic organisms, because they often obtain at least some of their carbon from dissolved carbonate rock.During the Miocene epoch—which stretches from 23.03 to 5.333 million years ago—apes underwent a period of massive evolutionary change, with more than 40 species appearing.But the epoch has a relatively poor fossil record; prior to the discovery, there were no cranial fossils found in Africa at all dating between 14 and 10 million years ago.While there is no doubt that the site is millions of years old, the precise age of the specimens has been contentious.Dating techniques produced wildly different ages for Little Foot, ranging between 2 to 4 million years old.

Our solar system formed about 4.6 billion years ago.The skull also contains unerupted adult teeth, teeth that have formed but not emerged into the mouth.The researchers used X-ray imaging to reconstruct the teeth, which indicated that the ape belonged to a new species.The age of the carbon in the rock is different from that of the carbon in the air and makes carbon dating data for those organisms inaccurate under the assumptions normally used for carbon dating.

This restriction extends to animals that consume seafood in their diet.The findings have been published in the journal fossils in the entire world.
