It is said that in the mists of time, the islands of New Zealand were lost, Atlantis-like, beneath the ocean. But a newly discovered fossil reptile suggests this theory does not hold water.
Marc Jones of University College London, UK, and colleagues found the portions of fossilised reptile jaw on New Zealand's South Island.
The wear patterns of the teeth suggest its owner had two parallel rows of upper teeth, and a single row of lower teeth that slotted in between. The only reptile known to have this type of jaw is the endangered tuatara and its ancestors.
