Archaeological dating isotopes

Last year, another study indicated that dogs had been domesticated separately in Europe and in East Asia.

An international team of scientists led by evolutionary geneticist Krishna R. The second dog, whose remains were recovered from Germany’s Cherry Tree Cave, lived about 4,700 years ago.

Easter Island (or Rapa Nui) is known for two things: giant stone heads and the cautionary tale of an isolated civilization that destroyed itself through reckless misuse of environmental resources.

But new analysis of archaeological remains might rewrite the narrative, painting the Rapa Nui people in a more positive light.

The sarcophagus will be taken to the Museum of London and the bones will be analyzed.

To read more about the archaeology of the city's Roman past, go to "London's Earliest Writing.".

"One of the resources that they supposedly used up was trees that were growing on the island.

Those trees provided canoes and, as a result of the lack of canoes, they could no longer fish.

The acoustic data was then used to create 3-D, slow-motion depictions of the echoes as moving circles originating from the place where the sound was reflected.

Atoms of the same element that have different numbers of neutrons are called isotopes. Most carbon on Earth exists as the very stable isotope carbon-12, with a very small amount as carbon-13.

Here’s an example using the simplest atom, hydrogen. Carbon-14 is an unstable isotope of carbon that will eventually decay at a known rate to become carbon-12.

Archaeologists think the coffin was opened in the eighteenth century, but they are not sure if the infant’s remains were removed at that time.

“We always knew this site had the potential for a Roman cemetery, but we never knew there would be a sarcophagus,” said Gillian King of Southwark Council.
