00:00A dinosaur once walked on land so huge, it could rival a blue whale in length, not heavier.
00:06The blue whale still wins by weight.
00:08That animal was Patagotiton, a giant plant-eating dinosaur from what is now Argentina.
00:14It lived around 100 million years ago and was among the biggest land animals ever known.
00:20Its body stretched roughly 122 feet, or about 37 meters.
00:25Nearly the length of two London buses parked end-to-end.
00:29That estimate comes from fossils found in Patagonia.
00:32Bones so huge they shocked scientists.
00:35One thigh bone alone was taller than most people.
00:38When scientists reconstructed it, the full creature was almost unbelievable.
00:43Patagotiton may have weighed around 70 tons, about 10 elephants combined.
00:47Every step moved a living mountain on four pillar-like legs.
00:51Its power was size, a long neck, a huge body, and the need to eat almost endlessly.
00:58Imagine standing beneath it, legs like tree trunks, neck above the forest, body blocking the light like a moving wall.
01:05The fossils revealed just how enormous dinosaurs could become.
01:09Today, only its bones are left.
01:11But they point to a world filled with giants.
01:14A world where a dinosaur that could rival a blue whale in length once walked on land.
