Although all three dinosaurs represent significant finds, the predatory theropod in particular is sure to bring publicity to the Australian Age of Dinosaurs Museum of Natural History and the Queensland Museum, which jointly worked on the excavations and diagnoses of the dinos. There’s nothing quite like a giant predatory allosauroid in terms of stirring the public’s interest in paleontology and stimulating museum attendance numbers.
Named for the Diamantina River and one of Austrailia’a National songs (“Waltzing Matilda”), Diamantinasaurus matilda was a 16-meter long (52-foot) sauropod.
Nicknamed Matilda, she is the more stout of the two new sauropods and left behind a variety of fossils, including a pelvis:
Left reconstructed pelvis in lateral (A) view. Left ilium in anterior view (B) showing the position of the sacral vertebrae. Right pubis and ischium in medial (C), proximal (D) and lateral (E) views. Right ischium in lateral (F) and medial (G) views. Reconstructed right and left ischia in dorsal view. Abbreviations: ip, ischial peduncle; iip, iliac peduncle of ischium; of, obturator foramen; pa, pubio-ischial contact; pip, iliac peduncle of pubis; ppd, pubic peduncle; ppp, preacetabular process of ilium; s, sacrum; sym, fused ischial symphysis.
Wintonotitan wattsi, or “Watts' Winton Giant" was also around 16-meters in length, but sported a more elongate neck than Matilda.
Nicknamed Clancy, he was diagnosed from a variety of fossils, some partially articulated, including several vertebra:
Partial dorsal centrum in lateral (A) and posterior (B) views. Isolated neural spine in anterior view (C). Anterior caudal vertebrae of Wintonotitan wattsi. Anterior caudal vertebra in lateral (D) and anterior (E) views. Anterior caudal vertebra in posterior (F), lateral (G) and ventral (H) views. Anterior caudal vertebra in anterior (I), lateral (J) and ventral (K) views. Abbreviations: plc, pleurocoel; pcdl, posterior centrodiapophyseal lamina; prel, prespinal lamina; spl, spino-prezygopophyseal lamina.
"The cheetah of his time, Banjo was light and agile," "He's Australia's answer to Velociraptor, but many times bigger and more terrifying," said the article’s lead author Scott Hocknull of the Queensland Museum.
As evidence of his ferocity, here are a few of Banjo’s teeth:
Isolated teeth in labial (A, C, E, F, G, I, J, L) and labial (B, D, F, H, J, K) views. A–B. Anterior dentary tooth or premaxillary tooth. C–L. Dentary teeth.
