This prehistoric animal was a flying reptile.  When dinosaurs ruled on land, Pterodactyls ruled the skies.  A Pterodactyl had some hollow bones, much like a bird's bones.  But a Pterodactyl was not a bird, because all birds have feathers and a Pterodactyl had no feathers.  It didn't fly like a bird either.  Instead, it soared off cliffs or trees, then glided on warm air currents rising from land or water below.
