Fossilised shark teeth

Remains of the extinct shark Carcharodon angustidens were found in limestone deposits in North Otago. The deposits were thought to have formed about 26 million years ago, when the area was 50–100 metres under the sea. These teeth and a vertebra have been partially freed from the surrounding limestone block. Carcharodon angustidens was larger than any living shark, with an estimated length of 9 metres and a weight of 8 tonnes.
