Agustinia is a genus of sauropod dinosaur with a type of armour unique to "Agustinia" individuals only. It lived about 116 to 100 million years ago in Argentina. The type species ("Agustinia lugabuei") is named in honour of Dr. Giancarlo Ligabue, the discoverer of "Augustinia". The original generic name was ""Augustia"", which, as it turned out, was already preoccupied by a beetle (see also: "Megapnosaurus", "Protognathosaurus").
