• The discovery of a distinctively tyrannosaur-like hipbone in Victoria, Australia, however, might change the way scientists think about the distribution—and evolution—of this infamous group of dinosaurs

• "The absence of tyrannosauroids from the southern continents was becoming more and more anomalous as representatives of other 'northern' dinosaur groups started to show up in the south," Paul Barrett, of the Department of Paleontology at the Natural History Museum in London

• The hipbone fossil is 30 centimeters long

• "The bone is unambiguously identifiable as a tyrannosaur because these dinosaurs have very distinctive hip bones," - Roger Benson

Reflection:

My biology class better prepared me to understand this article because of out time learning about the process of evolution. We did a project with the evolution of birds and that helped me to understand the article.
