00:00Palaeontologists in Argentina have uncovered massive human-sized bones they say may belong
00:09to the largest dino to ever walk the earth. The fossils, dating to 98 million years ago,
00:16appear to be 20% larger than those of the current largest titanosaur on record,
00:22according to the National University of La Matanza. That gargantuan dino stretched as
00:27long as four school buses end-to-end and weighed roughly the same as a dozen elephants.
00:33Titanosaurs were among the largest sauropods, long-necked plant-eaters that lived from the
00:38late Jurassic period to the end of the Cretaceous. The newly discovered titanosaur is one of many
00:44that have been found in South America in recent years. Much of the skeleton remains trapped in
00:50the rock, and scientists aren't quite ready to declare whether it belongs to a new species.
00:55The deciding factor could be the large limb bones, such as the femur or humerus, often used to
01:02determine a dinosaur's body mass. The findings were published in the journal Cretaceous Research.
