SCIENTISTS in Bolivia have found the world's largest group of dinosaur foot-prints. The footprints up to one metre long were found near the town of Sucre, 700 kilometre southeast of the capital La Paz. Christian Meyer, a Swiss palaeontologist and his colleagues have studied the site and analysed the prints for the last two months. The prints were first discovered by Bolivian scientists two years ago. The footprints are whole and it is believed that the creatures might have been walking in a muddy lake.

Meyer called on the authorities to protect the site, warning that unless something was done the footprints could disappear within 20 of time years because of rain and wind erosion. Several different kinds of dinosaur footprint have been identified including that of a giant tyrannosaurusrex estimated to be up to 24 metres high.

These findings support the theory that the valley had once been home to a large lake where the dinosaurs came to bathe, he said.
