Million years ago fossil leakey dating
Mary Leakey was born on February 6, 1913, in London, England.
“Why didn’t Homo erectus take these tools with them to Asia?The researchers chiseled away chunks of the mudstone at Kokiselei to later analyze the periodic polarity reversals and come up with ages.At Lamont-Doherty’s Paleomagnetics Lab, they compared the magnetic intervals with other stratigraphic records to date the archeological site to 1.76 million years., a precursor to modern humans, was using advanced tool-making methods in East Africa 1.8 million years ago, at least 300,000 years earlier than previously thought.The study, published this week in Nature, raises new questions about where these tall and slender early humans originated and how they developed sophisticated tool-making technology.The KNM-ER 1470 cranium, discovered in 1972, combined with the new lower jaw KNM-ER 60000; both are thought to belong to the same species.
The lower jaw is shown as a photographic reconstruction, and the cranium is based on a computed tomography scan.
Her find was truly remarkable; the fossil, believed to be more than 18 million years old, was the first species of the primate genus to be discovered from the Miocene era.
Mary Leakey further helped to unravel mystery surrounding the origins of humankind with her 1959 find: That July, while Louis was resting, recovering from a bout of the flu, Mary discovered the partial skull of an early human ancestor.
A team led by Meave Leakey, daughter-in-law of famed scientist Louis Leakey, found facial bones from one creature and jawbones from two others in Kenya.
That led the researchers to conclude that man's early ancestor had plenty of human-like company from other species.
” In the summer of 2007, a team of French and American researchers traveled to Kenya’s Lake Turkana in Africa’s Great Rift Valley, where earth’s plates are tearing apart and some of the earliest humans first appear.
