#Velociraptor with wings 3d series#

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.

Feather quill knobs in the dinosaur Velociraptor. As Norell himself says, “If animals like Velociraptor were alive today our first impression would be that they were just very unusual looking birds.” Discoveries like these further blur the distinction between this dinosaur lineage and their modern descendants.īirds are now all classified as living dinosaurs, but some palaeontologists argue that there is a case for classifying dromaeosaurs as birds. To their ancestors, Velociraptor and its kin would have been like prehistoric ostriches, having abandoned flying for a running life.įeathers can join the list of bird features shared by dromaeosaurids, including wishbones, nest brooding and hollow bones. Its smaller ancestors probably did use their feathers for flight (or at the very least, efficient gliding), and Velociraptor kept them but co-opted them for other purposes. Instead, Turner suggest that Velociraptor could have used its feathers to display to mates or rivals, to shield their nests from the cold, or to manoeuvre while running. For its weight, its forearms were too small to provide powered flight, and feathers there wouldn’t have helped the animal to retain much heat. But Velociraptor‘s forearm plumage probably fulfilled neither function. But this only works for small dinosaurs, smaller still than Velociraptor.įeathers allow birds to fly and to keep themselves warm. At these places, the specific mixture of sediment and low oxygen levels delays the process of decay long enough for soft body parts, like feathers, to become preserved. The most beautiful feathered fossils hail from special sites called, a kind of universal graveyard where an amazing diversity of prehistoric species is preserved. Turner and co aren’t surprised – these outlines have only ever been found in the smallest of dinosaurs. Several well preserved Velociraptor skeletons have already been found but palaeontologists have never found the outlines of feathers that typifies the fossils of species like Archaeopteryx and Microraptor. They probably looked much like those of today’s birds, rather than the hair-like proto-feathers of its ancestors. The quill knobs also suggest that Velociraptor‘s feathers had a distinctly modern style. The bottom two show the equivalent structures in a modern vulture, and how feathers are attached to them. You can see them in the top two images above. These knobs are direct evidence that Velociraptor carried a row of feathers on its forearm, probably about 14 by Turner’s count. The team recognised these as quill knobs, small lumps of bone that act as attachment points for feathers. They were studying the forearm of a Velociraptor unearthed in 1998, when they noticed six evenly spaced knobs of bone on the back edge. The breakthrough came from Alan Turner and Mark Norell from the American Museum of Natural History and Peter Makovicky of the Field Museum of Chicago. With feathered ancestors and evolutionary cousins, it was always extremely likely that Velociraptor also had a feathered coat but until now, that was always an educated guess. These species were primitive members of the dromaeosaurids, a group of small, agile predators that Velociraptor also belongs to. Some were just covered in a downy fluff, while others like Microraptorhad fully-formed wings and were probably capable of true flight.

It began in the late 1990s when Chinese palaeontologists found a stunning series of dinosaur fossils with distinct traces of feathers around their bodies. Since Jurassic Park aired, dinosaurs like Velociraptor have received something of a makeover. And in 2007, scientists found good evidence that it was covered in feathers. The actual dinosaur was smaller, slower and used its infamous claw to stab (or possibly climb) rather than disembowel. In Jurassic Park, the role of Velociraptor was played by computer-generated reptilian actors, that bore little resemblance to the real deal.
