Pterodaustro Wading in Shallow Lagoon Waters
A unique pterosaur named Pterodaustro steps through shallow water in a coastal lagoon near a river delta. Featuring a long, upward-curved bill, the bird-like reptile moves along the calm aquatic margin. Water flows gently through the lagoon habitat where shallow channels meet the coast.
Filter-Feeding Pterosaurs in Prehistoric Lagoons
Pterodaustro lived along coastal lagoons during the Cretaceous period in what is now South America. Its lower jaw contained over one thousand bristle-like teeth that formed a dense comb for strain-filtering tiny plankton and small crustaceans from shallow water. This feeding method is very similar to how modern flamingos filter food from salty lagoon lakes today.
Natural Colors of Pterodaustro and Lagoon Landscapes
- Pterodaustro plumage and skin: Muted pinkish-tan, grayish-white, or pale peach tones from dietary carotenoids
- Curved bill: Dark horn-brown or slate gray along the strain-filtering lower jaw
- Shallow lagoon water: Clear pale aqua, light teal, or sandy yellow near the shore
- River delta mud and sand: Light grayish-brown, beige, and fine silt tan
