The body of Piatnitzkysaurus, we know, is very allosauroid in its general shape. As such, and given key characteristics of the skeleton, it was at one point labelled as a basal carnosaur. Piatnitzkysaurus was probably never considered to be an allosauroid entirely on account of the fact that it was an Argentinian dinosaur and, correct me if I have forgotten, there are no prominent Argentinian allosauroids. However, subsequent studies on megalosauroids by Benton have determined that Piatnitzkysaurus was in fact a megalosaur. It is definitely not an abelisauroid or a tyrannosauroid theropod. What does everyone think?
