Yeah, Rebbachisaurus was African (Niger), and it was from around the same time
period as Spinosaurus and Ouranosaurus.  Amargasaurus was from Argentina, but
I think that if the sail was used for "climatic" reasons like in Spinosaurus,
Ouranosaurus, and Rebbachisaurus other dinosaurs from Cretaceous Argentina
would have had sails also.  It was probably used to make it look bigger to
predators, or used as a rivalry display.  Or it could have supported a thick
back hump.
