<\/a>Scientists studied the tailbones of two-legged, feathery dinosaurs called oviraptors.<\/p>\n
“Their tails were not only very, very flexible, but quite muscular,” researcher Scott Persons, a vertebrate paleontologist at the University of Alberta in Canada, told LiveScience<\/a>. “They could not only move them sinuously to strike a pose, but also hold it to do a muscular dance with the tail.”<\/p>\n Previous research shows these small dinosaurs had a bone crest on their head, which would also grab a mate\u2019s attention.<\/p>\n “I think like peacocks, oviraptors were strutting their stuff by shaking their tail feathers to show off,” Persons said. “Between the crested head and feathered-tail shaking, oviraptors had a propensity for visual exhibitionism.”<\/p>\n More research needed<\/strong><\/p>\n Persons wants to continue his research. He wonders if the bone structure differs between male and females.<\/p>\n “Maybe they were larger in males, as we see in modern-day birds,” Persons said. “The problem there is that the tip of the tail is one of the rarest parts of a fossil skeleton to find, so it might be hard to discover evidence of these sexual differences.”<\/p>\n Another recent discovery in the dino world<\/strong><\/p>\n Paleontologists have unearthed a rare species of dinosaur; one with a beak like a parrot and a body the size of a small dog.<\/p>\n The \u2018Pegomastax\u2019 was lodged in a rock that Paul C. Sereno, a paleontologist at the University of Chicago and a dinosaur specialist, dug up almost 30 years ago.<\/p>\n With a strong jaw, self-sharpening teeth and spikes like a porcupine, paleontologists believe it was built as a \u201cnimble two-legged porcupine.\u201d<\/p>\n<\/a>
