Ancient toothed turtles survived until 160m years ago

Today’s turtles don’t have teeth; they cut off their food using hard ridges on their jaws. But their ancestors were not so dentally challenged. A team of international researchers has now discovered that turtles with remnants of teeth survived 30 million years later than previously thought. The researchers found evidence of this at a major excavation site in China’s western Autonomous Region of Xinjiang.
