The dinosaur is a Protoceratops, and since this is one of the most common dinosaurs found in the rich fossil beds of the Gobi Desert, it was not deemed to be very significant.But the scientists say it is the first example of a dinosaur being preserved with its own footprints. recent examination of the 80-million-year-old specimen revealed a single footprint preserved in the rocks encasing the fossilised bones. Polish and Mongolian fossil hunters first unearthed it in 1965 in Mongolia.
