Lusitanosaurus is widely regarded as a dubious genus because of the lack of fossils that were used to describe it. The maxilla in question was originally thought to be from a stegosaur, but today it is considered to be from an ankylosaurian. Beyond this it is hard to infer anything further other than in life the dinosaur was likely a herbivore and quadrupedal like other members of the Thyreophora, and again this is why the genus is regarded as dubious.
