Researchers from Japan’s Okayama University of Science and the Mongolian Academy of Science came across a massive footprint that may have been left behind by a dinosaur in the Gobi Desert.
The fossil is more than 4 feet long with imprints of a Titanosaur’s claws. The long-necked herbivores stretched nearly 100 feet from tip to tail and stood almost 70 feet tall. Because of their enormous size, they walked on large stump-like legs that lacked toes, which might break under their weight.
The fossil footprint was created between 70 and 90 million years ago during the Cretaceous period.
