This interesting filter-feeding pterosaur had over 1000 modified teeth that formed a bristle-filter for straining nutrition from the water. Like modern flamingoes, Pterodaustro probably waded shallow brackish lagoons in pursuit of small crustaceans to trap in its bill and swallow. It also had a peculiarly long tail for a pterodactyloid and is a relatively well-known pterosaur being represented by hundreds of fossil specimens.
