Huge dinosaur footprints found on cave roof
Dinosaur footprints measuring up to 1.25 metres long have been found deep inside a cave in France — on the roof. The tracks were made 166 million to 168 million years ago, when three dinosaurs traversed the shoreline of a sea. The site was then at the planet’s surface, but geological processes have buried and tilted the sediments, and the prints are now on the cave’s roof, 500 metres underground. Researchers say the footprints probably belong to an unknown species of titanosaur, a category of long-necked herbivorous dinosaur that includes some of the largest animals ever to walk on Earth.
