SummaryScientists have newly identified a species of microraptor from a 120 million-year-old fossil found in northwestern China.The winged dinosaur was about the size of a barn owl and glided between trees hunting birds.The well-preserved shoulder bones could offer new clues about how these feathered predators evolved the ability to fly.AI-generated summary was reviewed by a CNN editor.A 120 million-year-old fossil found in what’s now northwestern China is changing how scientists think about an unusual group of predatory dinosaurs known as microraptors.The location where the fossil was unearthed adds to the known geographical range of the smaller, gliding cousin of the sickle-clawed velociraptor.The bones also represent the most recent definitive microraptor specimen in the fossil record, expanding the timeline for how long the feathered dinosaurs existed.A new analysis of the intact shoulder and forelimb bones, first mentioned in a study abstract in 2010, showed the fossil belonged to a previously unknown microraptor species. The research team has named the dinosaur Jian changmaensis, according to the study published Thursday in the journalAnnals of Carnegie Museum.Jian references a one-winged bird in Chinese mythology as a nod to the dinosaur’s birdlike characteristics. The species name was also a nod to the Changma Basin in Gansu province, where the fossil was uncovered — and so far, it’s the only undoubtedmicroraptor specimen to be found outside northeastern China.“Jian changmaensis reveals that non-avian dinosaurs lived in what is now the Changma Basin, an area famous for its fossil birds,” said study coauthor Dr. Matt Lamanna, senior dinosaur researcher and Mary R. Dawson Curator of Vertebrate Paleontology at the Carnegie Museum of Natural History in Pittsburgh, in a statement.“Our team has recovered more than one hundred bird fossils at Changma, but only this single non-avian dinosaur specimen. Jian provides critical new information on the biological history
