Correct!
Pterodaustro used its thin teeth to filter tiny animals like brine shrimp out of the water.
Pronunciation: tair-o-DOW-stro gee-NA-zoo-eye
Lived: around 100 million years ago
Fossil Found: in central Argentina
Wingspan: 8 feet (2.5 meters)
Diet: small arthropods, crustaceans, mollusks
Cool Fact: The teeth of Pterodaustro were packed so closely that a single inch of the jaw might contain 60 teeth (24 per centimeter)!
A typical meal for Pterodaustro was:
Scientists think Pterodaustro may have had a pinkish hue because:
it was a close relative of flamingos
it had a similar diet to flamingos
it lived in the same habitat as flamingos
Correct!
Flamingos eat brine shrimp, and those shrimp eat a special kind of bacteria that make natural coloring pigments. These pigments make their way up the food chain -- from bacteria to brine shrimp to flamingos -- to produce pink feathers.
Scientists think stones found in the stomach of Pterodaustro helped this animal digest its food.

Fact
These "stomach stones" may have helped Pterodaustro grind up food. Some birds today swallow stones to help them digest food.
Most pterosaurs that lived at the time of Pterodaustro had thin, comblike teeth.

Fiction
Pterosaur teeth came in many shapes and sizes. They also could be daggerlike for stabbing prey or tiny for snatching insects in flight. Some pterosaurs had no teeth at all!

There are several living animals that use filter feeding to acquire food like Pterodaustro did when it was alive. Probably the most familiar ones are the flamingo and ostrich.
