A team of international scientists led by researchers from British University of Portsmouth and the German Museum of Natural History, the most accurate and refined dinosaur of all appearance, discovered the State Museum of Natural History Germany. They say that it highlights how birds like the peafowl have inherited their ability to boast their breathtaking colored bristling.
According to a study published in Cretaceous Research, what distinguishes the new dinosaur, the two-man chicken size, who lived 110 million years ago in what is now northeastern Brazil, is the presence of long fur beneath its back and sharp hard stripes leading out of its shoulders. These are qualities that have never been seen before in the fossil record.
This dinosaur was named Ubirajara Jubatus, named after the Indian spear master, Tupi, referring to the tapes on its shoulders, while Jubatus came from the Latin meaning (maned) or the crowned.
According to scientists, the dinosaur from inside was normal with a skeleton similar to many small dinosaurs from the former Jurassic era. From outside it was very different. Ubiragara was the first non-bird dinosaur to be found in a leather preserved in the ancient subcontinent of Gondwana. Using X-ray, researchers involved in the study discovered the previously hidden structural elements and soft tissue, which allowed researchers to construct a clear image of this strange dinosaur.
Scientists believe that the bizarre cassettes of this dinosaur that emerge from his shoulders, believed to be made of keratin, are of the same material that makes up hair and nails, and were used to impress or intimidate enemies.
David Martel, a professor of biology at Portsmouth University, who helped study, says, “these tapes do not resemble anything you have seen in nature before, there are many other strange dinosaurs, but this dinosaurs does not resemble any of them.”
The researchers described the long, flat, and solid shoulder strips of keratin as “ambiguous”, and were placed on the shoulder so as not to impede the freedom of movement in his arms and legs, thus limiting the animal’s ability to hunt, prepare, and send signals.
The tapes are not sheets or escaped, nor are they feathers in the modern sense. But they look like unique structures for this animal. Scientists believe that these elaborate structures may have improved the chances of a young dinosaur surviving.
While many dinosaurs have skeletons, rings and decorations, which they may have used to boast, this small dinosaur has used keratin, which is a much better alternative to a small animal, because – the keratin – it does not need much energy from the body like bones to produce it. It is lightweight, flexible and can be replaced regularly if damaged.
Male, not female
Although there is no evidence of this, Professor David Mattel believes that dinosaur is male, owing to the disparity between male and female birds, as it is male birds that have the advantages to attract females to cross.
“The sample is likely to be male, and also young, which is surprising because the more complex projection capabilities are for adult males,” said Martel.
Modern birds are famous for their impeccable bristles and shows used to attract their comrades. Dinosaur Ubirajara makes it clear that this tendency to boast is not unique to birds, but something that birds inherited from their dinosaurs.
For his part, researcher Robert Smith of Portsmouth University, a co-study, points out that the features of this little dinosaur are alive, raising the question of why it is so so so so so so so so so so much visible to both its prey and the animals that it wishes to pretend to be.
