Dino-mite discovery! Bizarre prehistoric species that looked like a 'huge pig with a turtle's beak and tusks' roamed Tanzania 240 million years ago - and it could change the dinosaur timeline

But the new discovery suggests those rocks may not be as old as scientists had previously believed.Since Dinodontosaurus is now known from both Tanzania and South America, the researchers were able to link the geological sequences in the two regions and show that they are of equivalent age.Radiometric dating from South America suggests these dinosaur-bearing rock sequences could be up to 10 million years younger than equivalent rocks in South Africa.This means the Tanzanian rocks can no longer be regarded as preserving the oldest potential dinosaur fossils, prompting scientists to reassess when and where dinosaurs first evolved.
