Graphic released by Australian paleontologist Adam Yates, based at the University of the Witwatersrand, on Wednesday Nov. 11, 2009 in Johannesburg, South Africa, shows a newly discovered dinosaur species that roamed the Earth about 200 million years ago which may help explain how the creatures evolved into the largest animals on land. Fossils, marked on the outline, were found in the town of Senekal, near Bethlehem in the Northern Free State, in South Africa.
