The findings of Bronk Ramsey and his team favour the earlier date — and possibly even a decade earlier than that.

Most of the samples were taken from tombs known to be associated with the reign of specific pharaohs.

Because the order in which these pharaohs had ruled — and the approximate lengths of their reigns — was already known, the samples could be examined as a group.

Humans have always has this morbid fascination with death and the dead.

Thus, they've always deemed to preserve their dead all through different ages and thousands of years.

However, radioisotope dating may not work so well in the future.

Anything that dies after the 1940s, when Nuclear bombs, nuclear reactors and open-air nuclear tests started changing things, will be harder to date precisely.

This paper presents a brief recollection of the discovery of the Iceman “Ötzi”, an extraordinary archaeological find which opened up a window to prehistoric life some 5000 years ago.

, is the first to use high-precision measurements of radioactive carbon isotopes to produce a detailed timeline for the reigns of Egyptian pharaohs from about 2650 BC to 1100 BC.

Plants absorb carbon-14 as they grow, and the radioisotope decays naturally over time after they die.

Measuring carbon-14 levels in artefacts made of organic material allows archaeologists to determine their age.

Traditionally, the beginning of that era has been tied to an astronomical bearing on the star Sirius.
