- Extra specimens discovered later, together with vertebrae, a part of the toes, skulls, and extra
- Different specimens discovered nicknamed: Alex, Oliver, and Ann
- Mentioned “Ann”, the newly found out, just about whole cranium in episode 441 (fourth Diamantinasaurus specimen discovered, and 2nd cranium discovered, and essentially the most whole sauropod cranium present in Australia)
- Ann confirmed that Diamantinasaurus is carefully associated with Sarmientosaurus, which lived round the similar time and at a an identical paleolatitude
- Dinosaurs could have moved between Australia and South The us by way of a land connection thru Antarctica
