英語で学ぼう!About Celebrating the StaurikosaurusOn this day in 2010, Alcober OA and Martinez RN published a silhouette reconstruction of the skeleton of the Staurikosaurus.About the Doodle:During a dig in 1936, paleontologist Llewellyn Ivor Prince found a theropod (a carnivorous, bipedal dinosaur) specimen at the Santa Maria Formation in southern Brazil. Thanks to radiocarbon dating of sediments surrounding the fossil, during the late Triassic period, about 225 million years ago. Also called the “Southern Cross Lizard,” the dinosaur was named after the Southern Hemisphere constellation.Prince’s discovery is the only evidence of the Staurikosaurus to date, so our knowledge of the species is limited. From the findings we have, the Staurikosaurus was large for an early dinosaur — it was around 2 meters long, 80 cm tall, and weighed 30 kg, which is close to the weight of a large dog. Staurikosaurus had a long tail and ran on two legs, and its fossils suggest that it was quite fast for its size. The predator also had serrated teeth that were curved towards the back of its throat, which helped with catching and holding prey.The discovery of Staurikosaurus has helped paleontologists better understand the early evolution of dinosaurs. So, we'll be forever roaring with excitement for the Staurikosaurus!
