Ancient Plant-Eater Rewrites History: Tyrannoroter Heberti First Herbivore

• Scientists discovered Tyrannoroter heberti, a 307-million-year-old tetrapod, challenging previous beliefs about early land herbivory.
• The creature, smaller than a football, possessed broad, conical teeth perfectly suited for shearing and grinding tough vegetation.
• This discovery indicates plant-eating on land began much earlier than imagined, among animals once thought to be strictly carnivorous.
• Tyrannoroter heberti roamed during the Late Carboniferous, thriving in lush environments with abundant vegetation.
• The study, led by paleontologist Arjan Mann, reshapes understanding of early terrestrial ecosystems and the evolution of food webs.
