Russian scientists unearth new species of dinosaur

Scientists claim to have discovered a new species of dinosaur which roamed the earth 100 million years ago.

Nicknamed the Sibirosaurus, the creature is thought to be related to the giant Titanosaurs, which could grow to 40 metres and weighed up to 90 tonnes.

The find was made in Russia when experts discovered fossils encased in rocks on the banks of the Kiya River in Western Siberia in 2008.
