Which titanosaur skulls? The only one I can think of that might
look like that of _Nemegtosaurus_ is the skull of _Antarctosaurus
wichmannianus_. Aside from the fact that some authors
(Upchurch, and maybe McIntosh too) question whether _A.
wichmannianus_ is really a titanosaurid, the skull known for this
species is not in excellent condition and (like that of _Nemegto_) is
open to interpretation on how it was really constructed. The partial
skull known for _Malawisaurus_ is not at all like that of
_Nemegtosaurus_, nor like that of any diplodocoid.
I keep on hearing about a nicely-preserved skull of a definite
titanosaurid that was found somewhere in South America, relatively
recently. Can anyone confirm?
