Archaeodontosaurus was a close relative of the famous sauropods, the long-necked giants. Although smaller and more primitive, it already displayed the herbivorous adaptations that would later dominate in sauropod lineages. Its teeth are broad, leaf-shaped, and serrated, designed for shredding tough vegetation.
