Loricosaurus (meaning "armour lizard") is a genus of sauropod represented by a single species. It is a titanosaurian that lived near the end of the Late Cretaceous period, approximately 71 million years ago in the late Campanian or early Maastrichtian. Found in the province of Neuquen, Argentina in the Allen Formation. Due to the presence of armour, at first it was thought that it was an ankylosaur, but today it is considered to be the armour of a titanosaur.
