Scientists have found a new species of pterosaur that lived 200 million years ago along with the dinosaurs. The fossilised jawbone of the creature was unearthed by scientists at the Smithsonian's National Museum of Natural History in 2011.

A Smithsonian-led team of researchers have discovered North America's oldest known pterosaur, the winged reptiles that lived alongside dinosaurs and were the first vertebrates to evolve powered flight.

Eotephradactylus mcintireae’ is the oldest-known flying reptile from the continent and roamed the skies 209 million years ago.

The 209-million-year-old fossil offers clues to the evolution of the reptiles, which have more than 150 named species including the well-known pterodactyl.
