Ancient man unearthed near No Mans Acres field in Hollingbourne

A 3,500-year-old early Bronze Age man has been discovered near Hollingbourne – and now he’s ‘speaking’ to scientists.

1/4. The crouched human skeleton found at Hollingbourne is believed to be 3,500 years old
Archaeologists unearthed the man, believed to have been in his teens or early 20s, next to a field called No Mans Acres, which lays just on the border of Harrietsham.

His complete skeleton – thought to date back to about 1,500BC – was found in a 3ft-deep barrow.

Dr Paul Wilkinson, of the Kent Archaeological Field School, who led the investigation, said: “In a way, he’ll be now talking to us over thousands of years as scientists at the University of Kent examine his remains to establish his age and how he died.

“His teeth will also give a clue as to what part of the world he came from. [...]

Ice core data supports ancient space impact idea

New data from Greenland ice cores suggest North America may have suffered a large cosmic impact about 12,900 years ago.

A layer of platinum is seen in ice of the same age as a known abrupt climate transition, US scientists report.
The climate flip has previously been linked to the demise of the North American "Clovis" people.

The data seem to back the idea that an impact tipped the climate into a colder phase, a point of current debate.

Rapid climate change occurred 12,900 years ago, and it is proposed that this is associated with the extinction of large mammals - such as the mammoth, widespread wildfires and rapid changes in atmospheric and ocean circulation.

All of these have previously been linked to a cosmic impact but the theory has been hotly disputed because there was a lack of clear evidence. [...]
