The dinosaur of the day: Diamantinasaurus

• Titanosaur that lived within the Late Cretaceous in what’s now Australia (Winton Formation)
• Regarded like a compact, sturdy sauropod
• Had a protracted tail and walked on all fours
• Didn’t have a very lengthy neck
• Medium sized, estimated to be 52 ft (16 m) lengthy and weigh as much as 28 tons

• Sort species is Diamantinasaurus maltidae
• Described in 2009 by Scott Hocknull and others
• Genus identify means “Diamantina lizard”
• Refers to the place it was discovered (close to the Diamantina River)
• Species identify comes from the Australian music, “Waltzing Matilda” (written by Banjo Peterson in Winton in 1895). In accordance the paper that named Diamantinasaurus, it’s “one in every of Australia’s Nationwide songs” and Winton is “Matilda Nation”

• Holotype included a part of the shoulder, arms, arms, ribs, a part of the pelvis, and proper leg
• Fossils discovered on the “Matilda Web site” at Elderslie Sheep Station close to Winton, in Queensland, Australia
• Holotype is nicknamed “Matilda”

• Extra specimens discovered later, together with vertebrae, a part of the ft, skulls, and extra
• Different specimens discovered nicknamed: Alex, Oliver, and Ann
• Talked about “Ann”, the newly found, almost full cranium in episode 441 (fourth Diamantinasaurus specimen discovered, and second cranium discovered, and essentially the most full sauropod cranium present in Australia)
• Ann confirmed that Diamantinasaurus is carefully associated to Sarmientosaurus, which lived across the identical time and at an identical paleolatitude
• Dinosaurs might have moved between Australia and South America through a land connection by means of Antarctica
• Oliver is a juvenile specimen
