Brazilian palaeontologists show models comparative of "Nemicolopterus crypticus", a new species of tiny prehistoric flying reptile, and a other pterosaur found in Brazil, during a news conference at a National Museum in Rio de Janeiro, Brazil, Feb. 11, 2008. The toothless flying reptile lived in gingko forests that existed some 120 million years ago in present north-eastern China. With a windspan of 10 inches (250 mm), the species is one of the smallest pterosaurs known to date. (AUSTRAL FOTO/RENZO GOSTOLI)
