Oh there were still stubby-necked titanosaurs as well - like _Isisaurus_ and
_Mendozasaurus_, both of which had rather short necks (though not nearly as
short as the absurdly stubby-necked _Brachytrachelopan_). It now appears
that the titanosaur group also produced very long-necked forms too, like the
mamenchisaur-mimic _Erketu_.
What an amazing group the titanosaurs were. We have huge taxa
(_Argentinosaurus_, _Puertasaurus_) and - by sauropod standards - miniature
taxa (saltasaurines, _Bonitasaura_, maybe _Magyarosaurus_). Many
titanosaurs had armor, sometimes quite bizarre (especially if _Agustinia_ is
a titanosaur). Most titanosaurs had tail vertebrae that were procoelous,
but almost every other kind of articulation was represented too (biconvex,
amphicoelous, opisthocoelous), as well as more than one kind in the same
caudal series. One titanosaur (_Bonitasaura_) might even have had a beak.
