In the Who's Who of the Mesozoic world, pterosaurs are often referred to as the flying reptiles. No scene from the Age of Reptiles is complete without at least one of them dipping their leathery wings off in the distance. But pterosaurs weren't the only reptiles to swoop through the air during this time. A newly-named species from the Triassic rock of Poland is a reminder that other reptiles took to the air in their own ways.
Paleontologists Jerzy Dzik and Tomasz Sulej have named the little reptile Ozimek volans. There's no modern equivalent for this 237-228 million year old critter. The known skeletons and elements recovered so far come together in the form of a reptile with a long neck, spindly front arms, a shield-like pectoral girdle, and elongated hind limbs that likely supported a membrane which allowed Ozimek to glide.
Ozimek wasn't the only reptile with such an arrangement. Another, related animal called Sharovipteryx had leg wings, too, although the long neck and other aspects of Ozimek anatomy mark Dzik and Sulej's animal as something different. Both, however, appear to be protorosaurs - a group of oddities and enigmas that paleontologists are really just beginning to understand.
Little Ozimek probably wasn't an active flyer, though. The osteology of its hind limbs and hips, Dzik and Sulej point out, would have made flapping impossible. Instead Ozimek was more like a reptilian version of a flying squirrel, making its own way into the air during a time when the distantly-related pterosaurs were starting to flap through the skies.
