All members of the clade thyreophoran were quadrupedal (walked on 4 legs).
The statement is True.
An order of armoured ornithischian dinosaurs known as Thyreophoran existed from the Early Jurassic through the end of the Cretaceous period. The body armour arranged in rows along the body is a distinguishing feature of thyreophoran.
The well-known Stegosauria, or plated dinosaurs, and Ankylosauria, or armoured dinosaurs, as well as their more primitive members, such Scutellosaurus and Scelidosaurus, make up the majority of the Thyreophora.
The majority of ankylosaurs, including Euoplocephalus, Nodosaurus, and Palaeoscincus, walked close to the ground on short, stocky legs in a quadrupedal (4) stance and had relatively low and wide body shapes. The length of the rear legs was greater than the length of the front legs, like in stegosaurs, although not to the same degree as in Stegosaurus.
