The original paper was by Coria and Salgado, and appeared in the summer of
1995 in Nature.

I believe a longer paper will be available in the forthcoming Gondwana
dinosaurs volume of the Memiors of the Queensland Museum.

Nobody has really dealt with this yet, but the adaptations of this puppy
aren't much different from those of other big allosauroids
(Carcharaodontosaurus, Acrocanthosaurus, etc.).  It occurred in the same
horizon as Rebbachisaurus tessonei, and is somewhat lower in the Rio Limay
Fm. than Argentinosaurus (but perhaps that genus will be found in the same
horizon eventually).  Much as in other allosauroid-dominated communities,
sauropods seem to be the most common known large herbivores.
