RE: Tyrannosaur analogs in the south?

The Late Cretaceous top predators of Gondwana were the Abelisauridae. Not
as big as the tyrannosaurids, nor were they particularly cursorial, but
like their distant northern kin they had stumpy arms.
As an addendum to this, I'll add that there were other very large,
stumpy-armed theropods, including carcharodontosaurids such as
_Giganotosaurus_ and _Tyrannotitan_.
Some quite large basal tetanurans had quite short and stumpy forearms, like
_Torvosaurus_ and _Xuanhanosaurus_. The antebrachium was short and stumpy,
but also <massive>. Like the carcharodontosaurids, these guys do not appear
to have been all that cursorial.
