What is "aepisaurus"

Aepisaurus (; derived from the Greek: αἰπεινός - 'lofty/high' and σαυρος - 'lizard', i.e. "lofty lizard") was a genus of sauropod dinosaur from the Albian-age Lower Cretaceous Grès vert of Départment du Vaucluse, France, around 100 million years ago. It is an obscure genus from an unknown family, represented by a single humerus, now lost. Despite its lack of popularity, or perhaps because of it, it has been misspelled several ways in the scientific literature, with multiple dates given to the year of description as well.
