In Arizona a new species of dinosaur suggests that dinosaurs didn't spread across the world by overpowering others, but by taking advantage of a natural disaster that killed their competitors. sarahsaurus, the new dinosaur, challenges the view that dinosaurs are successful animals that outcompeted other species whenever and wherever they wanted to. The sarahsaurus was studied by an international team of scientists, including Robert Reisz, Tim Rowe, and Hans-dieter Sues. All of the paleontologists put together their findings from different parts of the skeleton, and discover its evolutionary significance. The remains of the dinosaur showed that it was 4.3 metre long, a bipedal plant eating animal, had a small head but long neck, and weighted about 113 kilograms.
OPINION:
Is that all the article is going to tell us? I was waiting for the answer as to why they believe dinosaurs weren't powerful. Even though it lacked a true ending it was still a great article and easy to read. I think its pretty cool that all these paleontologists from around around the world started finding remains of this dinosaur all around the same, and bring together their knowledge. One again this article was well written even though i believe it could have ended better.
