A team of Japanese and Mongolian paleontologists have discovered the largest dinosaur footprint ever found in the Mongolian desert. The footprint is as big as a fully grown person, measuring 42 inches long and 30 inches wide. It belongs to the Titanosaur, a dinosaur who, as its name suggests, was very, very large. Titanosaurs roamed the Earth about 70 to 90 million years ago. Herbivores with long necks, when they were fully grown, they could weigh up to 90 tons and stand over 60 feet tall.

"This is a very rare discovery as it's a well-preserved fossil footprint that is more than a meter long with imprints of its claws," a statement by the Okayama University of Science, who was involved in the study, said. Scientists believe it's likely we will find more giant dinosaur skeletons, though we're getting close to finding the biggest fossils out there.
