New Australian Sauropods Shed Light on Cretaceous Dinosaur Palaeobiogeography Received: 15 April 2016 Stephen F
www.nature.com/scientificreports OPEN New Australian sauropods shed light on Cretaceous dinosaur palaeobiogeography Received: 15 April 2016 Stephen F. Poropat1,2,*,, Philip D. Mannion3,*, Paul Upchurch4,*, Scott A. Hocknull5, Accepted: 13 September 2016 Benjamin P. Kear1,6, Martin Kundrát7,8, Travis R. Tischler2, Trish Sloan2, George H. K. Sinapius2, Published: 20 October 2016 Judy A. Elliott2 & David A. Elliott2 Australian dinosaurs have played a rare but controversial role in the debate surrounding the effect of Gondwanan break-up on Cretaceous dinosaur distribution. Major spatiotemporal gaps in the Gondwanan Cretaceous fossil record, coupled with taxon incompleteness, have hindered research on this effect, especially in Australia. Here we report on two new sauropod specimens from the early Late Cretaceous of Queensland, Australia, that have important implications for Cretaceous dinosaur palaeobiogeography. Savannasaurus elliottorum gen. et sp. nov. comprises one of the most complete Cretaceous sauropod skeletons ever found in Australia, whereas a new specimen of Diamantinasaurus matildae includes the first ever cranial remains of an Australian sauropod. The results of a new phylogenetic analysis, in which both Savannasaurus and Diamantinasaurus are recovered within Titanosauria, were used as the basis for a quantitative palaeobiogeographical analysis of macronarian sauropods. Titanosaurs achieved a worldwide distribution by at least 125 million years ago, suggesting that mid-Cretaceous Australian sauropods represent remnants of clades which were widespread during the Early Cretaceous. These lineages would have entered Australasia via dispersal from South America, presumably across Antarctica. High latitude sauropod dispersal might have been facilitated by Albian–Turonian warming that lifted a palaeoclimatic dispersal barrier between Antarctica and South America. -
STUDY GUIDE What to Know About This Relaxed Show
STUDY GUIDE What to know about this relaxed show: There will be dinosaurs! And, yes dinos make noise, stomp around and are really big. But we will be making accommodations to make sure they aren’t as loud and scary as you might think. For this show: • Lights in the theatre will stay low during the show, instead of turning all the way off. • The sound levels will be lowered when needed. • Fidgets, headphones, and weighted toys will be available to help children feel more organized and settled. • Even though we will lower the sound and ease the lights we want to make sure it’s a great experience. • A quiet room will be available if children need to leave the theatre to feel more settled or regroup during the show. • The dinos will limit their engagement in the audience, but you may come up on stage if invited. To get an idea of what the show will be like before we make adjustments, visit these weblinks: https://www.youtube.com/watch?v=67z2GSCSlIg https://www.youtube.com/watch?v=_-0n8OgV7IU INTRODUCTION This publication was created as a study guide for students preparing to see Erth’s DINOSAUR ZOO Live™ which is touring theatres throughout North America beginning January 2014. Erth’s DINOSAUR ZOO Live™ takes the audience on a tour through pre- historic Australia, bringing an eye-popping array of ancient creatures to life on stage. They will observe and interact with extraordinarily life-like creatures, just like those that inhabited the Southern Hemisphere millions of years ago. -

Poropat*1,2 Introduction: Ask the average person in the street to name an Australian dinosaur, and you will be lucky if you get a correct answer. If they say crocodile, they are in the right postcode but have the wrong address. If they say emu, then they are correct, strictly speaking, but they are either lucky or being smart. If they say kangaroo, back away slowly and avoid eye contact. -
