Scientists have found that around 110 million years ago a two-legged chicken-sized Cretaceous period dinosaur might have existed alongside the shores of an ancient sea, which is known as northeastern Brazil now. Experts have said that the dinosaur might have been dependent on hunting insects and small vertebrates such as frogs and lizards for a living. As per the findings of the study, the internal anatomy of this creature has been similar to many small dinosaurs from the Jurassic time. However, from the outside, it looks like a chicken. This dinosaur has been known as Ubirajara Jubatus. Experts have said that it may have a mane of hair-like shape. It would have had two unique still ribbons like traits as well, which is made out of keratin sticking out of its shoulders. Keratin is known for making hair and fingernails.
The lead author of this study, David Martill has said that there are many different types of dinosaurs; however, this one has been unique. The study has been put together by scientists from the University of Portsmouth in England. Scientists have said that Ubirajara’s hair like shape seems to be an elementary form of feathers, which are known as protofeathers. As per the findings of the study, many dinosaurs have owned some sort of feathers. Experts have said that birds as well have been evolved from small-sized feathered dinosaurs around 115 million years ago. The findings of the study have been released in the journal called Cretaceous Research. This dinosaur appears quite hairy instead of feathery from a distance, said the lead author of the study. Martill has said that it shows that it may have hair like protofeathers all over the body, but over time, this feature has remained around the neck arms, and back. Protofeathers on its back have been quite long, which looks like a mane, which is a unique feature in dinosaurs.
Scientists have said that Ubirajara’s ribbon-like feature might have been used for attracting mates, intimidating foes, or inter male rivalry. This feature might have been utilized as the display by this dinosaur, said the scientists. Such kinds of displays are prepared by male animals such as peacock elaborates its tail feathers. It shows this Ubirajara dinosaur has been male. The lead author of the study has said that the ribbon-like feature stemming from the shoulders is something, he has never seen before in nature. He has said that though it is not possible to find out the color combination of this creature from the fossils, however, the experts think it might have been colorful.
