90-Million-Year-Old Dinosaur Tracks Found In Argentine Patagonia

A number of dinosaur tracks, some of them up to 1.2 meters in diameter, have been found in Argentine Patagonia, in the province of Neuquén (in the southwest of the country), Jorge Calvo, a geologist at the National University of El Comahue, confirmed Wednesday. “There are abundant tracks of sauropod dinosaurs of various sizes,” the researcher said in a press release in which he characterized the discovery as “spectacular,” in a region popularized as the Argentine ‘Jurassic Park.’ The tracks were found some days ago by chance, by a yoga teacher who was performing her exercise routine in the open air in the region of Los Barreales, in the province’s northeast. “First I saw a really strange depression in the ground, then another and another, and I realized that they were the tracks of a dinosaur walking,” Silvia Cuevas said when recounting her find. Calvo emphasized that “these are the same fossil-bearing strata that have made this site one of the richest locations for dinosaurs and associated fauna in South America.” “The Los Barreales tracks are well-preserved, but for now are lacking details with which to establish relationships,” explained Calvo, director of the Lago Los Barreales Center for Paleontological Research. The scientist calculated that the tracks found “have an age of 90 million years.” The region is considered one of the most important paleontological deposits in South America, where finds have been made of fossils from the Cretaceous period. Argentina drew the attention of the scientific world at the end of the 1980s, when fossils of Argentinosaurus huinculensis, the largest herbivore known, forty meters in length, were discovered in the province of Neuquén. In 1993 the remains of Giganotosaurus carolinii, the largest carnivorous dinosaur in the world, were found along with dozens of other discoveries in deposits still being explored.
