There will be an exhibition about sabre-toothed cats in the natural history museum in Leiden, the Netherlands.
It will be from 1 December till 6 January 2008.
The exhibition is about Homotherium latidens. Until recently, scientists thought that species had become extinct 300,000 or 400,000 years ago.
However, on 16 March 2000, a lower mandible was found in the North Sea, near the Bruine bank. It was only 28,000 years old; so, it proved the older theory wrong. Then, during the Ice Age, the southern part of the North Sea was still land.
