World's longest sauropod trackway discovered in France

In a massive breakthrough, researchers have discovered the world's longest sauropod trackway in France, a path that covers nearly 500 feet of Sauropod footprints.

According to the research team led by scientists with the Laboratoire de Géologie de Lyon, the large herbivore dinosaur was at least 115 feet (35 meters) long and weighed 35 tonnes.

These dinosaurs with long necks lived 150 million years ago during the Jurassic Period and the trackway consists of 110 steps left by the stomping beast.

A release this week from the French National Center for Scientific Research says, "The presence of large dinosaurs indicates the region must have been studded with many islands that offered enough vegetation to sustain the animals."

The researchers published their findings in the journal Geobios with the title "The dinosaur tracksite of Plagne (early Tithonian, Late Jurassic; Jura Mountains, France): The longest known sauropod trackway."

First sauropod tracks were discovered in 2009 in the village of Plagne, which is located in France's Jura Mountains.
