World’s longest sauropod dinosaur trackway brought to light

In 2009, the world's largest dinosaur tracks were discovered in the French village of Plagne, in the Jura Mountains. Since then, a series of excavations at the site has uncovered other tracks, sprawling over more than 150 meters. They form the longest sauropod trackway ever to be found. Having compiled and analyzed the collected data, which is published in When sauropod tracks were discovered in the French village of Plagne in 2009 - near Lyon - the news went round the world. After two members of the Oyonnax Naturalists' Society spotted them, scientists from the Paléoenvironnements et Paléobiosphère research unit (CNRS / Claude Bernard Lyon 1 University) confirmed these tracks were the longest in the world. Between 2010 and 2012, researchers from the Laboratoire de Géologie de Lyon ( LGL-TPE ) supervised digs at the site, a meadow covering three hectares. Their work unearthed many more dinosaur footprints and trackways.
