A Filter-Feeding Reptile on Saline Flats
Pterodaustro was a highly specialized pterosaur that inhabited shallow, salty lagoons and evaporative salt basins. Its upward-curved beak contained hundreds of needle-like bristle teeth designed to filter tiny organisms from shallow water. The surrounding environment features vast crusts of salt, calm evaporative pools, and accumulated shell deposits.
Why Salt Flats Turn Pink
Salt flats and saline lakes often exhibit a pink or reddish color due to microscopic algae and salt-loving bacteria called halophiles. These organisms produce colorful pigments to protect themselves from intense sunlight in harsh, salty conditions. Modern animals like flamingos feed on small crustaceans living in these pink waters, taking on similar pink hues.
