Struthiosaurus (Latin struthio = ostrich + Greek sauros = lizard) is one of the smallest known and most basal genera of nodosaurid dinosaurs, from the Late Cretaceous period (Campanian-Maastrichtian) of Austria, Romania and France in Europe. It was protected by body armour. Although estimates of its length vary, it may have been as small as 2.2 metres (7.2 ft) long.
