Species: S.‭ ‬emilieae‭ (‬type‭)‬.
Diet: Herbivore.
Size: Estimated about‭ ‬14-‭ ‬15‭ ‬meters long.
Known locations: USA,‭ ‬Montana,‭ ‬Carbon County‭ ‬-‭ ‬Morrison Formation.
Time period: Tithonian‭? ‬of the Jurassic.
Fossil representation: Partial post cranial skeleton.

       Although it seems to have lived towards the end of the Jurassic,‭ ‬Suuwassea appears to have been a basal diplodocid sauropod dinosaur that was more primitive in form than other better known sauropods such as Diplodocus and Apatosaurus.‭ ‬This would make Suuwassea a late surviving form.‭ ‬At an estimated length approaching fifteen meters,‭ ‬the Suuwassea holotype individual would have been considerably smaller than many other North American diplodocids,‭ ‬and perhaps at greater risk from predatory theroopd dinosaurs similar to genera such as Allosaurus and Torvosaurus.
