Mesozoic Earth - Dorygnathus at altitude

	Dorygnathus at altitude A flock of pterosaurs of the genus Dorygnathus soars high over a rugged, Early Jurassic European landscape of coniferous trees of the genus Wollemi approximately 180 million years ago. Dorygnathus had a wing span of about 3 feet and its large, curved fangs suggests that it dined primarily on fish. Like all pterosaurs, Dorygnathus was a flying reptile, not a dinosaur (the flying descendents of the dinosaurs live on today as birds).
