It was found in the desert in Chad by an international team and is thought to be approximately seven million years old.
I knew I would one day find it... I've been looking for 25
years, said Michel Brunet of the University of Poitiers, France.
Scientists say it is the most important discovery in the search for
the origins of humankind since the first Australopithecus
ape-man remains were found in Africa in the 1920s.
The newly discovered skull finally puts to rest any idea that there
might be a single
missing link between humans and chimpanzees,
Analysis of the ancient find is not yet complete, but already it is clear that it has an apparently puzzling combination of modern and ancient features.
It shows us there wasn't a nice steady progression from ancient
hominids to what we are today, he told BBC News Online.
It's the most important find in living memory, the most
important since the australopithecines in the 1920s.
It's amazing to find such a wonderful skull that's so
old, he said.
What is the skull's significance?
The skull is so old that it comes from a time when the creatures which were to become modern humans had not long diverged from the line that would become chimpanzees.
There were very few of these creatures around relative to the number of people in the world today, and only a tiny percentage of them were ever fossilised.
So despite all the false starts, failed experiments and ultimate winners produced by evolution, the evidence for what went on between 10 and five million years ago is very scarce.
Grandparent, great uncle, great aunt?
There will be plenty of debate about where the Chad skull fits into the incomplete and sketchy picture researchers have drawn for the origins of the human species.
A find like this does make us question the trees people have built
up of human evolution, Chris Stringer of the Natural History
Museum, London, UK, told the BBC.
Sahelanthropus tchadensis, as the find has been named, may turn out to be a direct human ancestor or it may prove to be a member of a side branch of our family tree.
The team which found the skull believes it is that of a male, but even that is not 100% clear.
They've called it a male individual, based on the strong brow
ridge, but it's equally possible it's a female, said
Future finds may make the whole picture of human evolution clearer.
We've got to be ready for shocks and surprises to come, he
The Sahelanthropus has been nicknamed Toumai, a name often given to children born in the dry season in Chad.
Full details of the discovery appear in the journal Nature.

Another blow to the fundamentalist creationist theory
supporters. Every find over the last 80 years has pushed back the
window of human origin, even finds of early hominid culture pushes the
development of technology and culture back to earlier and earlier
times. We underestimate ourselves and our ancestors! The
was in Africa and it was very old.
