The baby tuatara was discovered by staff during routine maintenance work at the Karori Wildlife Sanctuary in the capital, Wellington, conservation manager Raewyn Empson said.
From the 1960s to the 1980s the oldest radiocarbon dates derived from analysis of settlement sites in New Zealand were 1000–1100 AD or even a little earlier.
During the 1990s these dates were systematically re-assessed as the technique became better understood, and many problems were found with earlier dates.
Therefore, by measuring the amount of carbon-14 a once-living object retains, scientists can determine its age.
While the radiocarbon dating method can provide close estimations of age, the figures should not be regarded as exact.If you're ready to meet your Dunedin match then join us today!Here you can find elegant Victorian buildings, colourful student headquarters and a population who knows that they’ve found a pretty amazing place to call home.At Elite Singles we cater for New Zealanders in search of real, long-term love.Our membership base is mostly made up of singles aged 30-55 who are educated, professional and in search of a committed, fulfilling relationship with someone really like-minded.University of Otago zoology professor Jon Waters said there was a clear pattern as cold-adapted sub Antarctic penguins and sea lions "suddenly moved north to mainland New Zealand, right at the start of the Little Ice Age, around 1500AD." When the temperature dropped, humans were inclined to move north, easing the hunting pressure while hunting reduced the local populations of wildlife.
