Strange dinosaur has scientists enthralled

About 110 million years ago along the shores of an ancient lagoon in what is now north-eastern Brazil, a two-legged, chicken-sized Cretaceous period dinosaur made a living hunting insects and perhaps small vertebrates like frogs and lizards. This dinosaur, called Ubirajara jubatus, possessed a mane of hair-like structures while also boasting two utterly unique, stiff, ribbon-like features probably made of keratin – the same substance that makes up hair and fingernails – protruding from its shoulders.
