Definition
A labyrinthodont refers to an individual amphibian from the group Labyrinthodontia/Labyrinthodonta. These extinct amphibians are noted for their complex, folded tooth structure. They represent early tetrapods that transitioned to land. Labyrinthodonts were diverse and occupied various ecological niches. They are a critical link in understanding vertebrate evolution. Think of them as the bridge between aquatic and terrestrial life. π
