Scientist for the last hundred years have been searching for a crator or remnants of space rock.Finally in 2008 scientist think they have found an impact site at the bottom of a nearby lake Cheko.He was considered to be the brutish ancestor link to man in the evolution chain, the intermediate stage between man and ape.

Graphite, one of the softest materials known, is a form of carbon that is primarily used as a lubricant.
Although it does occur naturally, most commercial graphite is produced by treating petroleum coke, a black tar residue remaining after the refinement of crude oil, in an oxygen-free oven.
The skull was unlike anything seen before, having a flattened cranium with a heavy brow ridge above large eye sockets.
Nearby, workers also uncovered an assortment of thick and heavily fossilized bones.
In succeeding years many further specimens have been found, not only in the German Neander Valley, but in with rickets, caused by a deficiency of vitamin D.
He considered that the flattened head was caused by repeated powerful blows (his examination was done pre Darwinism 1859).When objects of the Old Kingdom and Middle Kingdom of Egypt yielded carbon dates that appeared roughly comparable with the historical dates, Libby made his method known.With initial large margin of error and anything that did not square with expectation, judged as contaminated, the method appeared to work and was hailed as completely reliablejust as the atomic clock is reliableand this nobody doubted.This black soot, also known as lampblack, gas black, channel black or carbon black, is used to make inks, paints and rubber products.It can also be pressed into shapes and is used to form the cores of most dry cell batteries, among other things.Atomic Number: 6 Atomic Weight: 12.0107 Melting Point: 3823 K (3550°C or 6422°F) Boiling Point: 4098 K (3825°C or 6917°F) Density: 2.2670 grams per cubic centimeter Phase at Room Temperature: Solid Element Classification: Non-metal Period Number: 2 Group Number: 14 Group Name: none What's in a name? Three naturally occurring allotropes of carbon are known to exist: amorphous, graphite and diamond.
