ShareNot only did the researchers find that Cooper was not a member of any previously described species, they also officially deemed the Australotitan dinosaur, or the “southern titan,” to be the largest known dinosaur to ever roam the outback. It likely weighed somewhere between 25 and 81 tons. At about 80 to 100 feet long and 16 to 21 feet tall at its hip, Australotitan is also within the top 10 to 15 largest dinosaurs in the world. For comparison, the Tyrannosaurus rex was only about 40 feet long and 12 feet tall.
With those stats, Cooper joins the ranks of the titanosaurs, a group of mega-beasts previously only discovered in South America. It lived between 92 million to 96 million years ago. The findings were published in the journal PeerJ. Mackenzie told ABC News that Australotitan was just “the tip of the iceberg” and that there are plenty of Australian sites brimming with potential for more fossil excavations. Australotitan was a plant eater, Hocknull noted, “so what was marauding around trying to eat these guys? We don’t have any evidence of that just yet.” Each discovery will help complete the story of Australia’s ancient past. (Read more.)
