The unusual fossil was found in Brazil and is the first of its kind from South America showing evidence of feathers. The study authors believe that the extended plumage would have been used for demonstration and would have indicated that the dinosaurs had consistent mating behavior.
“If confirmed, this discovery would be a significant discovery for two reasons: the first feathered dinosaurs from the southern continents and the strange display structure in dinosaurs from relatively early descent,” said Zheng, a paleontologist at the Vertbrett Paleontology Institute and a paleontologist in Beijing.
“Similar constructions have previously been reported from some very bird-like dinosaurs, but in those cases, ribbon-like formations are attached to the tail, which is normal, but in this new discovery, they are attached to the shoulder, which is” unusual, “Xu added. Was not involved in the research.He found some feathered dinosaur fossils in China.
The animal may have lived about 110 million years ago.
David Martell, a professor at the University of Portsmouth in the UK and author of the paper, said some birds today have ‘decorated shoulders’, including the male-standing bird- of F-Paradise, but it is rarely seen.
“We cannot prove that the specimen is male, but given the differences between male and female birds, it appears that the specimen was male, and even young, which is surprising given that most complex performance abilities are reserved for adult males.” He said.
“Looking at its outburst, we can imagine that the dinosaur could have gotten involved in an extended dance to show off its display structures.”
The study was published in the Cretaceous Research Journal on Monday.
Paleontologists now believe that many dinosaurs had feather or feather-like structures, but most of the fossil evidence to date has come from China and Germany.
Remains Limestone was mined to make slabs by miners found in the Creto Formation of northeastern Brazil and was exceptionally well preserved.
It shows a piece of long thick wax running down the animal’s back. His hands were also laced like fur below. It is believed that the believer was controlled by allowing it to be raised by muscles, just as a dog grows its bones or its buds grow when threatened, the authors said in a news release.
The name in the Tupi language means “lord of spears” after the dinosaur was named Yupirajra jubatus, and in Latin means walking or crested jubatus.
Some Brazilian paleontologists objected to the unusual fossils being taken from Brazil for the study. “This paper is controversial because the Brazilian constitution recognizes fossils as a cultural heritage,” Taisa Rodriguez Marcus da Silva, a professor at the Espirito Santo at Brazil’s Federal University, told CNN by email.
The paper states that the German State Museum of Natural History is part of the fossil collection at Karlsruhe, and was approved for export in 1995.
