World’s longest known Sauropod TrackThese photos show a 155 meter long dinosaur track found in Plagne, found today in the Jura mountains of France. During the Jurassic, 155 million years ago, this part of what is today central Europe was a tidal flat, where waters of the Tethys Ocean flowed up onto the continent and inundated lowlands in-between higher continental massifs. The Jurassic rocks of this area have been found to contain hundreds of dinosaur tracks, with quarries of them running through France and Switzerland. The dinosaurs walked in muddy soil along the edge of the Ocean and when the tide came in, those tracks were buried and eventually fossilized.This particular site was discovered in 2009. Excavation, as seen in the second photo, took over 3 years and 2700 human-days of work. 134 distinct prints were unearthed in this trail, produced by the dinosaur Brontopodus plagnensis. Local authorities have established a park at this site.-JBBImage credit and original paper:[http://bit.ly/2nwnWNF]Reference:[http://www2.cnrs.fr/en/3023.htm] -- source link
