Posed in a slow, diving turn, it scans the floor below, its birdlike head with malevolent gold and black eyes tilted to one side. At first glance, it may seem to be a giant bird from some science fiction film, but this beast is neither a bird nor a figment of a movie scriptwriter's imagination. It is a detailed, lifesized model of the ancient reptile, Quetzalcoatlus northropi, the largest flying animal on record twice as large as any bird that ever lived. The creature's double name refers to the serpentine Aztec god (Quetzalcoatl) and to the Northrop Flying Wing, an experimental airplane. The Smithsonian's reconstruction animal, the first of Quetzalcoatlus, represents the latest scientific thinking about the anatomy and flying lifestyle of these full-sca- long-extin- reptiles. Imagine Quetzalcoatlus swooping down and alighting in the dinosaur hall. If it folded its wings alnnit its large furry body and stood erect like a giant pelican on its strong, slender, long back legs, it would be tall enough to look many of the Smithsonians big dinosaurs directly in the Entire Stock of Sheets and Pillow Cases on Sale eye. In its lifetime, Quetzalcoatlus would certainly have been familiar with the e dinosaurs, even if it din't see with them.

The story behind Quetzalcoatlus begins in 1784 when Cosimo Collini, a secretary to Voltaire, first reported the discovery of pterosaur fossils in a limestone quarry near the Bavarian village of Eichstatt. Collini thought they were the remains of an amphibious mammal. It wasn't until the turn of this century that the fossils were established to be those of flying reptiles. Pterosaur remains have since been found on every continent except Antarctica. In the United States, the chalk deposits of western Kansas are a great ground. pterosaur Still, no one suspected that pterosaurs had grown to such gigantic size until 10 years ago, when a Texas Memorial Museum field party under the direction of Dr. Wann Langston turned up the massive fossilized pterosaur wing bones of Quetzalcoatlus in Big Bend National Park in west Texas. Later, similar but smaller bones thought to be those of Quetzalcoatlus juveniles were found elsewhere in the park.

Sale The Smithsonian model reflects recent of pterosaur biology and aerodynamics. Not too long ago, scientists believe that a pterosaurs wings were attached to both its front and back legs. Looking at the creature in this way, scientists found it difficult to understand how it flapped its wings and became airborne. One popular theory held that it launched itself off the cliffs and glided, flopping around on four legs like a bat when it landed. Padian and a number of other scientists dismiss this theory. They believe that the wings were only attached to the front legs and that Quetzalcoatlus was a soaring animal, a superb flying machine as perfectly adapted to the air as birds. advances in the understanding 6.75 standard Reg. $9 Sink into the gentle comfort of our luxurious Dacron fiberfill II polyester bedpillow.

Riding thermal updrafts, it stayed in the air all day with very little expenditure of energy and, when it landed, it walked around upright on its back legs like a bird. The Smithsonian Quetzalcoatlus model will never be put to the test of taking off and landing, but simply to make it biologically and aerodynamically plausible in flight took more than a year of work and a great deal of thought by Smithsonian scientists and modelmakers. Dr. Jessica Harrison, a paleontologist working on the development of the Smithsonian's new dinosaur hall, went to Texas in late 1979 to research and photograph Quetzalcoatlus fossils. Because there was so little data to work with, she had to use what she calls educated gueswork," drawing on such disparate fields of study as physics, biology, aeronautical engineering, comparative anatomy and even architecture. Harrison worked with Walter Sorrell, supervisor of the Smithsonian model shop, to produce a large, detailed wood and built on a scale of 2 fiberglass model inches to a foot. After some modifications based on suggestions offered by Padian (he thought the neck was too long), the museum had a pterosaur that could be enlarged to life size. To make the model more dynamic than the usual pterosaur recoast ruction, Harrison decided to depict it in a gentle,' banking dive. The big Quetzalcoatlus model was con-- . st meted in three sections body and neck, wings and head. It had to be engineered to be light and st rang so it could be suspended in the air without sagging. Modelmakers Bruce Hough and Ben Snouffer tackled the body and neck first, making a hollow wire mannequin and covering it with fiberglass. Next, they worked on the wings, the most time-consumi- and difficult part of the project. The wing bones of the pterosaur are one of the most distinctive features of its anatomy. Supporting the wing membranes, these bones are an evolutionary variation of the forelimb of an earthbound animal that walked on all fours. The inner wing bone, or humerus, linked the inner wing to the muscular body. The radius and ulna, the outer wing bones, were attached to a wrist and four fingers. The fourth finger was unique. It was greatly elongated up to 8 feet and supported as much as half of the length of the wing membrane. Hough and Snouffer constructed each of the two wings by gluing balsa wood voer a long steel wire armature, carving the wood to conform to the configuration of bone and flesh and then covering the wood with a thin coat of fiberglass. The membranes were formed with modeling clay and reinforced with strips of wood to get aerodynamically correct contours. Then, the clay model was cast in fiberglass. The pterosaurs head and slender beak were modeled by Jim Reuter, who had only a partial skull and jaw to work with. The fossils gave him some idea of the size but not the complete shape. Working with information supplied by Harrison and Dr. Nicholas Hotton, the Smithsonians fossil reptile curator, Reuter filled in the missing parts. I couldnt let my imagination run wild, Reuter says. It had to be scientifically plausible, but I was allowed two dramatic touches the malevolent eyes and a long, curved, ravenous tongue. Even though I enjoyed making the creature look somewhat evil, I dont dislike the animal. It was afragile creature and I think of it as being more like a butterfly than a fierce predator. The assignment of painting and furring Quetzalcoatlus was given to modelmaker Tree ODonnell. She stayed away from using dark green or typical reptile colors, choosing instead a subtle brown color that grades into a light buff on the creatures underside. The fossil record shows that some pterosaurs had fur, so Smithsonian scientists decided to cover the reptiles neck, torso and legs with synthetic fur. I did a lot of piecing and stitching, ODonnel relates. My experience with tailoring helped. I guess you could say that I fitted our Quetzalcoatlus with a custom-mad- e fur coat. Completely assembled and weighing less than the only about 140 pounds actual animal would have wieghed in life the finished Quetzalcoatlus model was suspenced with four steel cables from the ceiling of the dinosaur hall, where visitors to the Smithsonian may now see it peeling off towards them, as though in search of a 40-fo- ot meal. No one really knows what Quetzalcoatlus ate. Some pterosaurs have been found with marine fish in their stomachs, but in west Texas where Quetzalcoatlus lived there were no large bodies of water at that time. Would it have fed on a museum tourist if it were hungry? Smithsonian officials assure anxious visitors that its lifelike Quetzalcoatlus has had its last meal more than 65 million years ago.
