 The "teeth" were probably covered by the rhamphotheca in life, and there are two furrows running along the underside of the upper bill just inside the ridges which bore the "teeth".Thus, when the bill was closed only the upper jaw's "teeth" were visible, with the lower ones hidden behind them.Inside the eye sockets of at least some pseudotooth birds – perhaps only in the younger species – were well-developed salt glands.
