Their dorsal side processes are also fairly in-line with the level of the neural canal.

[4] Skull material from Malawisaurus, the sister taxon to Lognkosauria, indicates that lognkosaurians at least began with the big-nosed, rounded head shape of earlier titanosaurs and more basal macronarians.

[5] Lognkosauria was defined as the clade encompassing the most recent common ancestor of Futalognkosaurus dukei and Mendozasaurus neguyelap and all its descendants.

[4] Lognkosauria has been found to include other giant sauropods, such as Puertasaurus, Argentinosaurus, Patagotitan, Notocolossus, Drusilasaura and Traukutitan.
