Dr Adam Yates, a palaeontologist from the University of the Witwatersrand, looks at fossilised dinosaur bones as he announces the discovery of a new species of dinosaur in Johannesburg, South Africa, 11 November 2009. Approximately 195 million years old and dating from the early Jurassic period, the seven-metre-long vegetarian dinosaur, named Aardonyx celestae, was discovered near the town of Senekal in South Africa's Free State province. The Aardonyx was an animal close to the common ancestor of the gigantic sauropod dinosaurs, known popularly as 'brontosaurs', which were the largest backboned animals to walk on land. EPA/JON HRUSA
