Note:

The only difference in analysis done by Upchurch (1998) and Wilson (2002) is the position of genus Haplocanthosaurus. In Upchurch's analysis it lies below the Diplodocimorpha-Macronaria dichonomy, i.e. outside of the Neosauropoda.

Wilson places Haplocantosaurus within the Diplodocimorpha [his Diplodocoidea] as the most primitive member of the clade.
