Researchers from the University of Kansas in the United States and China’s Northeastern University reported their findings earlier this year. A report about the study was published in the Proceedings of the National Academy of Sciences.
BARBARA KLEIN: The researchers used the fossils of a dinosaur that lived one hundred twenty-five million years ago. But its bones were in very good condition. The researchers made a hardened reproduction of the bones, without changing their positions. Then they added clay to create a model of the dinosaur. Next, they added real feathers cut to the correct size. The result was a re-creation of an ancient Microraptor.

The research team built a light-weight model of the animal. This model was designed to glide, or move, in an almost effortless flight. The feathers on the flying model were made of plastic. The scientists carried out a series of test-launches with the wings in different positions. They found that the best position for gliding had the back two wings in a position similar to that of a flying squirrel. The body of that animal looks almost flat as it glides from tree to tree.
BOB DOUGHTY: Other experts have said the Microraptor probably flew with its back wings a little under and in a direction like that of the front wings. But the published report says that would have forced it to fly in a difficult position.
