Species
Edaphosaurus pogonias
Edaphosaurus pogoniasEdaphosaurus pogonias roamed the equatorial river deltas and floodplains of Early Permian North America, crushing fibrous vegetation with dense batteries of blunt palatal teeth. A prominent dorsal sail supported by elongated neural spines rose along its spine, uniquely adorned with knobby crossbars and lateral tubercles. As one of the earliest dedicated herbivorous tetrapods, it played a vital role anchoring terrestrial food webs before disappearing during the mid-Permian.
