Dinosaur fossil found in Brazil reveals new chicken-sized species

Paleontologists have discovered a chicken-sized dinosaur species with a mane of hair down its back and stiff ribbon-like structures projecting from its shoulders. The dinosaur, Ubirajara jubatus, is believed to have lived around 110 million years ago in northeastern Brazil. "There are...strange dinosaurs, but this one is unlike any of them," said professor David Martill, who helped lead the study.
