3.5-feet long dinosaur footprints found in Mongolia
A team of Mongolian and Japanese researchers has recently uncovered one of the biggest dinosaur footprints, measuring 3.5 feet long and 2.5 feet wide. It was discovered in Mongolia's Gobi desert and is reportedly 70-90 million years old. The footprint is believed to have belonged to long-necked Titanosaur, which could have been over 30 metres long and 20 metres tall.
