To celebrate its 200-year anniversary next year, the Australian Museum in Sydney will host the skeleton cast of Patagotitan mayorum, the largest dinosaur to have walked the Earth at nearly 38 meters long. The exhibit, set to open in November and displayed in the museum's basement hall, includes an original fossil thigh bone, which is the largest dinosaur fossil ever discovered. Museum CEO Kim McKay emphasizes that this massive creature weighed around 70 tonnes when alive during the Cretaceous period about 100 million years ago.

Story summary
The Australian Museum in Sydney will celebrate its upcoming bicentennial by hosting the skeleton of Patagotitan mayorum, the largest dinosaur ever discovered. At nearly 38 metres long and estimated to weigh around 70 tonnes, this colossal creature roamed Argentina’s Patagonia during the Cretaceous period, about 100 million years ago. Due to local laws preventing the whole skeleton from leaving Patagonia, a moulded cast will be displayed alongside an original fossil thigh bone—the largest dinosaur fossil ever found. The exhibit, scheduled for summer, will fill almost the entire length of the museum's touring exhibition hall in its basement, marking what chief executive Kim McKay calls "icing on the cake" during her 12-year tenure.
