Paleontologists have discovered a new kind of dinosaur with a very characteristic characteristic: a structure similar to a candle that works with your back, declared the London Museum of Natural Humanities.
The bones of the istiorachis macarthurae, named after British navigator Ellen Macar, who were beaten on the island of Wait, a small island on the southern coast of England, where he wandered more than 120 million years ago with other Iguanodon relatives, a group
Scientists are not quite sure why he had such an exaggerated feature in the form of a candle on his back, although they create that he could help dinosaurs attract a partner and recognize each other as members of the same species.
Earlier it was thought that this instance, found about 40 years ago, belonged to one of two types of iguanodonton, which was known to be inhabited by the island of White.
But when Dr. Jeremy Lockwood, Dr. Jeremy looked at his doctoral studies, he realized that “he had particularly long nervous spikes, which was very unusual.”
The definition of this distinctive characteristic, similar to a candle, helped to determine the dinosaur, which height about 2 meters and weighed about 1000 kilograms as a new species, Lokwood said. This Thursday he published his conclusions in Paleontology magazines.
“The opening of another iguanadon on the island of White shows that it was a very diverse territory in the early chalk,” he added. “I’m sure there will be more discoveries in the coming years.”
He found that Istiorachis Macarthurae lived at a time when the Iguanadone dinosaurs developed to develop more than higher spikes, he discovered.
“In part, we believe it was for muscle insertion,” Lockwood said.
“Iguanodons evolved from small beyond dinosaurs to much larger animals, which spent more time for all four, so they would need a stronger muscle support for their bones.”
Even in this context, the highway istiorachis macorturae is unusual.
Lockwood rejects a potential theory that suggests that a candle can help dinosaur to adjust the body temperature by saying that “a candle with many blood vessels will be very vulnerable to the attacks and can lead to massive blood loss if damaged.”
Instead, he believes that “sexual signboards is the most likely explanation”, which means that the candle performs a function similar to the tail of the male real turkey.
“If the characteristic is exaggerated for its practical function in living animals, it is invariably linked to evolutionary pressure to attract a partner. The candle of the walk seems to be another example of this,” he added.
