What are two ways of dating fossils

This estimate was actually reduced over his lifetime to between 20 Ma and 40 Ma and eventually to less than 10 Ma. Perry, in particular, a noted physicists and former assistant to Kelvin, showed that cooling calculations using different but equally likely assumptions and data resulted in ages for the Earth of as much as 29 Ga.

A conservation scheme to protect fossils, flora and fauna in a valley near Duntroon- which might be recognised by fans of the Narnia movies- has received $23,000 in funding from a water zone committee and QEII National Trust.

Property belonging to the Anatini Farmstay in the Waitaki Valley appeared in the 2005 film Fossilised shells, and dolphin and whale bones have been found on the site, which had been studied extensively by the University of Otago.

Of course, this was a close as Kelvin ever came to publicly recanting his position.

Later, after radioactivity had been proven to be a significant source of the Earth's internal heat, he did privately admit that he might have been in error.

In the past Maori rock art had been found on the property, but those sites had since eroded.

was published, the earth was "scientifically" determined to be 100 million years old. In 1947, science firmly established that the earth was 3.4 billion years old.

Hore said he had spent almost his entire life living on the property, and had always been aware of the fossilised shells, but the larger fossils were a more recent discovery.

"Long, long ago this valley was 100m under the sea," he said."The geologists can tell by the shells and fossils in the rocks.

The Alps 2 Ocean Cycle Trail already passes through the site and it is also part of the Vanished World fossil trail.

As one answer to his critics, Kelvin produced a completely independent estimate -- this time for the age of the Sun.
