"As far as I can tell they're describing a small coelurosaur from the

pleurocelos dorsales y sacros, pubis proyectado verticalmente e isquiones 
reducidos, El tamano del especimen es comparable con el conocido para los 
tyrannosauridos del Hemisfrio Norte."

The specimen is a juvenile individual that exhibits apomorphies of 
Coelurosaria, such as pleuroceolous dorsals and sacrals, a mesopubic pelvis 
and a reduced ischium, The "tamano" of the specimen is comparable to the 
tyrannosaurids of the Northern Hemisphere.

I'm not sure what "tamano" is.

"I take it they think its a tyrannosaurid. Not surprising to me. It's only a 
matter of time before an Abelisaurid (or even a spinosaurid) from Hemisfrio 
Norte is found..."

Isn't Spinosaurus known from the Northern Hemisphere?  And Suchomimus, too?  
And if you apply one of the two definitions of Spinosauridae, you could get 
Baryonyx as well.
