Currently recognized sauropod genera and species in the Upper Jurassic Morrison Formation of North America. Dyslocosaurus polyonychius potentially represents an additional valid sauropod species from this formation, but its stratigraphic provenance remains uncertain [5,18]. ‘Apatosaurus’ minimus might also represent a distinct sauropod species [19], although its affinities require further evaluation [5,13]. Note that the validity of Diplodocus longus (highlighted with an asterisk) is disputed and it is unlikely that this species can be diagnosed ([20] [and references therein]).
