Dinosaur egg is known as a rogue can be a diva with a tail like a feather fans spectacular flamenco dancer, a new study finds.
Oviraptor dinosaurs lived in the late Cretaceous period, about 75 million years. They got their name from the Latin "egg thief" because the first specimen was found near a clutch of eggs, as if the beast was flying, and later discoveries have shown that the eggs were probably years Oviraptor itself, even if the energy dinosaurs, and if you include eggs, is largely unknown.
But a new study shows that the experts what they ate, oviraptorids were shaking their tail feathers. The dinosaurs are exceptionally compact, flexible tails, says researcher Scott Persons, a graduate student at the University of Alberta. In combination with a variety of feathers attached to the end of the tail, this would be possible to put the peacock-like Oviraptor today.
Individuals who presented the study here on November 2 meetings of the Society for Vertebrate Paleontology Annual, began studying at the tails of several species of Oviraptor queue as part of a wider search of all theropods, a group of dinosaurs, which are closely related to modern birds. Oviraptors are interesting, said people living science, because they have a very strange tail bones of a strange arrangement.
"The tail of an Oviraptor from the tail of most other dinosaurs is really short," he said. "But he is not short in that it lacks many of the vertebrae, it is the shortest the individual vertebrae in the tail itself is a kind of well crushed. So they are tight. "
This provision dense bone would have been particularly flexible tails, it was said, in the same way as the backbone of the person, with its many bone interfaces can move sinuously like a hand, which is only a couple of joints.
Also suggests the comparison with the tails of modern reptiles, which had the tail oviraptorids particular muscle, People said. Trace fossils reveal that oviraptorids also came equipped with a feather fan at the end of their tails, attached to a piece of fused vertebrae no different from those found in the tail of modern birds.
"If you combine that having a muscular, highly flexible tail, what has it, that could be used to circumvent, at least, so that the wave of the range of tail feathers," Persons says.
And like modern birds, may well have flashed oviraptorids fans lined up to impress potential partners.
