In fact, the number of the dinosaur prints found on a slab of limestone4 measuring5 600 square meters in the Jura regions has reached more than 580. In total6, almost 2,000 dinosaur prints have been found so far in this corner of Switzerland. The Swiss researchers want the dinosaur-rich7 area to be added to the United Nations list of worldwide heritage sites8. The latest group of prints, which are kept in Hug’s laboratory, measure between eight and 20 centimeters long. The tracks were made by four-legged animal between 15 and 20 meters long and 2.5 meters high, and smaller two-legged animals. Hug said a group of scientists would study them to find the scientific value of the discovery by the end of 20059. “This will allow us to ask for UNESCO10 protection for these prints as part of the world’s heritage,” he said. UNESCO, the United Nations Educational Scientific and Cultural Organization, helps preserve valuable cultural and scientific sites across the world. Hug and his fellow scientists11 want to create a Geopark to allow people to visit the pre-historic sites. In the past year 20,000 visitors have already showed up12 for a look at the prints. 如仍有问题，请致电：64378912 咨询。 科普英语竞赛组委会办公室 2007年7月1日 |
