Thyreophorans were a group of fascinating dinosaurs known for their unique body armor. These dinosaurs lived during the Jurassic and Cretaceous periods and are divided into two main groups: stegosaurs and ankylosaurs. Stegosaurs, like Stegosaurus, had rows of large, bony plates along their backs and spikes on their tails. Ankylosaurs, like Ankylosaurus, were heavily armored with bony plates and had club-like tails for defense. Thyreophorans were herbivores, meaning they ate plants, and their armor helped protect them from predators. Imagine these incredible dinosaurs roaming ancient forests and plains, using their impressive armor to stay safe.
