Dinosaur hunters have discovered the remains of two creatures previously unknown to science.
Both sets of fossils were discovered in Antarctica - albeit at sites thousands of miles apart.
One of the creatures was a two-legged meat-eater standing up to 8ft tall. It died about 70 million years ago and was related to the ferocious tyrannosaurus.
The other one died about 130 million years ago. It was a four-legged
plant-eater related to the diplodocus.
The meat-eater's remains were found on an island which used to be the bottom of a shallow sea. They included fragments of an upper jaw with teeth still attached.
Pelvis
The other dinosaur was found on a 13,000ft mountain which used to be a muddy riverbed. Its remains included a 3ft-wide pelvis.
