Balaenognathus (IMAGE) University of Leicester Caption Short-tailed pterosaurs, like this Balaenognathus were adapted for a life on the ground. This bizarre creature boasted nearly 500 needle-like teeth in its jaws, and likely used them to filter-feed on tiny food items from shallow waters, similar to the feeding habits of modern flamingos.
