Abstract
Eggtooth development and morphology in the six-lined racerunner, Cnemidophorus sexlineatus, were examined using scanning electron microscopy. The anlage of the embryonic eggtooth emerges from the anterior surface of the palate relatively late during embryonic development. The eggtooth proper erupts through an epithelial sheath and grows anteriorly to project beyond the rostral scale. The mature eggtooth is hollow, has a wall made of enamel and dentine, possesses a sharply-curved body and has a flattened, pointed tip. The eggtooth is shed within several days after the young hatch.
