Don't forget _Puertasaurus reuili_, a truly absurd titanosaur from the
Maastrichtian of Patagonia:
Novas, Fernando E., Leonardo Salgado, Jorge Calvo and Federico
Agnolin. 2005. Giant titanosaur (Dinosauria, Sauropoda) from
the Late Cretaceous of Patagonia. Rev. Mus. Argentino
Cienc. Nat., n.s. 7(1): 37-41.

I direct your attention particularly to Fig. 3, which shows an
anterior dorsal of _P._ to be, if anything, slightly larger than one
of _Argentinosaurus_. This specimen is particularly spectacular as it
preserves a cervical so vast as to be comical -- about 118 cm long,
from prezyg to postzyg, and 140 cm _wide_, including the laterally
projected origins of the fused cervical ribs.
Woah! Dude! Extreme!
