Evolution of the Dinosaurs

Dinosaurs First Appear

Is there a continent where dinosaur fossils have never been found?

No. It was once thought that Antarctica was the only continent that did not have any dinosaur fossils. But in December 2003, researchers working in separate sites thousands of miles apart in Antarctica found what they believe are the fossilized remains of two species of dinosaurs previously unknown to science—one a primitive sauropod. In 2007, yet another dinosaur discovery was made in Antarctica: a new genus and species of dinosaur from the early Jurassic—a massive, plant-eating, primitive sauropodomorph called Glacialisaurus hammeri that lived about 190 million years ago.
