The nyctosaurus are large pterosaurs who are powerful fliers and so pil ot air-taxis over the skies of the pterosaur planet, Squawk Major. A pair of them took Teggs and his crew to the planet, but unintentionally put their lives in danger when they forgot how to fly and the taxi began to plummet. However, some quick thinking from Sprite, the dimorphodon, and even the alarm pterosaur ensured a safe landing. The puzzled nyctosaurus then gave the astrosaurs directions to the Palace of Perches.
