Eopinacosaurus is an ankylosaurid dinosaur that was originally assigned to Pinacosaurus, until a 2026 analysis reassigned it as a distinct genus. Like all ankylosaurs, it was a heavily armored quadrupedal herbivore. Notable defensive adaptations include the characteristic tail club, as well as sizable horns protruding backward from the head.
