![]() It was a bipedal, feathered carnivore with a long tail and an enlarged sickle-shaped claw on each hindfoot, which is thought to have been used to tackle and restrain prey. It nevertheless shared many of the same anatomical features. Smaller than other dromaeosaurids like Deinonychus and Achillobator, Velociraptor was about 1.5–2.07 m (4.9–6.8 ft) long with a body mass around 14.1–19.7 kg (31–43 lb). osmolskae, was named in 2008 for skull material from the Bayan Mandahu Formation, China. mongoliensis fossils of this species have been discovered in the Djadochta Formation, Mongolia. Two species are currently recognized, although others have been assigned in the past. 'swift thief') is a genus of small dromaeosaurid dinosaur that lived in Asia during the Late Cretaceous epoch, about 75 million to 71 million years ago.

Did they evolve for flight, or did they first develop for something else, and were later co-opted to be used as an airfoil? We don’t know the answer yet, but since new fossils of bird-like dinosaurs are being found at an incredible rate, maybe we’ll have it solved by the time the next Jurassic Park comes out. A big, short-armed animal probably wasn’t flying, so what was it doing with its wings? We don’t know for sure. It also has much shorter arms than Velociraptor or birds. Zhenyuanlong is fairly large for a close relative of birds, two metres long from snout to tail. It gives us new insight into this incredible moment in evolution. They are chapters in one of the greatest stories in the history of life: the evolutionary transition between fearsome carnivorous dinosaurs and their 10,000 feathered descendants that live on today, all over the world.Īnd this is why the discovery of Zhenyuanlong is really important. These small, fast-running, brainy predators are some of the closest relatives of birds. They fascinate me because they capture evolution in action. Far from being a scaly-skinned reptilian monster, Velociraptor would have been a fluffy, feathered poodle from hell.ĭinosaurs such as Zhenyuanlong and Velociraptor are some of my favourite fossils to study. Look at Zhenyuanlong and you see what the real Velociraptor would have been like. If you could see it alive you would probably make no distinction between it and, say, a turkey or a vulture. This is a dinosaur that looks just like a bird. Simple hairy filaments coat much of the body, larger veined feathers stick out from the tail, and big quill-pen-feathers line the arms, layered over each other to form a wing. It’s just the right environment for preserving the soft bits that usually decay before a fossil is formed. Its gorgeous chocolate-coloured skeleton was found by a farmer in 125-million-year-old rocks that were laid down in a quiet lake buried by volcanic ash. Our new dinosaur, Zhenyuanlong, is one of the closest cousins of Velociraptor. But because Velociraptor hasn’t been found in the perfect geological settings that fossilise soft tissues, we don’t know exactly what its feathers would have looked like.īut we have a better idea now, thanks to the discovery of a spectacular new dinosaur from northeastern China that I studied with my colleague, Junchang Lü of the Chinese Academy of Geological Sciences. If you look at the arm bones of Velociraptoryou can see a row of bumps, identical in size and shape to the quill knobs of living birds: the anchor points for big wing feathers. Palaeontologists have known this for a while. That’s because the real Velociraptor was a lapdog-sized predator covered in feathers. What I didn’t like, however, was that the Velociraptors were depicted as big, drab-coloured, scaly brutes. ![]() I study dinosaurs for a living and it didn’t bother me to see Velociraptors being used as hunting dogs for the sake of good cinema. It’s a preposterous storyline of course, but very entertaining. Tens of millions of people have flocked to theatres this summer to see Jurassic World, an action flick “starring” a team of trained Velociraptors that hunt genetically modified dinosaurs on command of their human master. ![]() Editor's note: The following essay is reprinted with permission from The Conversation, an online publication covering the latest research. ![]()
