[ad_1] WASHINGTON (Reuters) - An beautiful fossil of a fierce little Chinese language dinosaur dubbed the “dancing dragon” that lived 120 million years in the past - an older cousin of the Velociraptor - is displaying scientists that feathers grew otherwise on dinosaurs than on birds. An artist's rendering of the newly-discovered Chinese language feathered dinosaur Wulong bohaiensis is seen on this picture launched in San Diego, California, U.S. January 17, 2020. Erick Toussaint/Handout through REUTERSThe 2-legged Cretaceous Interval dinosaur, referred to as Wulong bohaiensis, was a bantamweight meat-eater - a bit larger than a crow - residing in a lakeside atmosphere, researchers mentioned. It possessed a scaly face, a mouth stuffed with pointy enamel and one notably harmful toe claw, and possibly hunted small mammals, lizards, birds and fish. Wulong’s fossil, unearthed in Liaoning Province in northeastern China, features a full skeleton in addition to tender tissues like feathers not often preserved in such element. Its lengthy legs and arms every had units of feathers that appeared much like these on chook wings, whereas a lot of the remainder of its physique was lined by fluffy filaments. On the finish of its lengthy, bony tail - fused right into a stiff rod - had been two very lengthy feathers. “The specimen of Wulong is a gorgeous fossil. With the feathers and claws, I think it would have been beautiful and just a little bit scary. I’d love to see one alive,” mentioned San Diego Pure Historical past Museum paleontologist Ashley Poust, who led the analysis revealed this week within the Anatomical Report journal. “I don’t think we know yet how it used its feathers,” Poust mentioned. “It seems likely that they helped with temperature regulation and signaling to other animals, but what this would have looked like and how much these functions mattered remains unclear.” Birds developed from small feathered dinosaurs roughly 150 million years in the past. However there have been many feathered dinosaurs that didn't fly, like Wulong. Scientists are keen to know the plumage variations between birds and these feathered dinosaurs. A detailed examination of bones confirmed this Wulong particular person was a few yr previous, a juvenile nonetheless rising. “Living birds shoot up to adult size very quickly, mainly as a way of getting strong enough to fly as soon as they can. But they may delay getting their adult feathers for a long time. Gulls, for example, don’t look like adults for three or four years even though they learn to fly in only three months,” Poust mentioned. The younger Wulong appeared to have an grownup’s plumage. “Here is an animal that has all kinds of signals of being a juvenile, outside its bones, inside its bones, in its joints,” Poust mentioned. “And it has long, isolated plumes extending from its already-very-long tail. This is quite different from living birds and tells us that these decorative feathers preceded adulthood in dinosaurs. Of course, perhaps they’re using these feathers in a very different way from living birds, too.” Wulong means “dancing dragon,” so named due to its fossilized skeleton’s active-looking pose. It belongs to a gaggle of meat-eaters referred to as dromaeosaurs, which additionally contains Velociraptor. That dinosaur lived 75 million years in the past in Mongolia and seems within the “Jurassic Park” movies.
