{"product_id":"0783421424791","title":"NOVA: The Four-Winged Dinosaur","description":"Paleontological research and understanding took a stunning leap forward in the year of 2002, when a team of scientists, working diligently in Eastern China, discovered a beautiful and yet terminally odd artifact: a fossil, estimated at around 130 million years old, of a crow-sized flying creature (dubbed 'Microraptor,' by Chinese archaeologist Xu Xing). The animal in question had four wings - two on its legs, and two on its arms. Scientists now theorize that this creature - and other feather-covered dinosaurs not unlike it - were buried and fossilized by the eruption of a nearby volcano. The PBS special NOVA: The Four-Winged Dinosaur journeys to the site of the discovery and joins a team of scientists from multiple fields, including aeromechanics, biomechanics and paleontology. The experts speculate at length on the flying methods of this strange species, and subsequently create a scale replica of the same creature, testing its flying abilities within a wind tunnel in an attempt to gain more scientific insight into Microraptor.","brand":"WGBH BOSTON VIDEO","offers":[{"title":"Default Title","offer_id":47094996107504,"sku":"0783421424791","price":19.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/0783421424791_p0.jpg?v=1763861503","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/0783421424791","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
