Yes, rebbachisaurs, dicraeosaurs, and true diplodocids are included in this
taxon.

Salgado et al. do not address the position of the Euhelopodidae (pity), but
(in my opinion) Upchurch has very convincingly placed them outside
Neosauropoda (= camarasaurids, brachiosaurids, titanosaurids, and diplodocoids).
