Giant Abelisaurs?

I KNOW there's too little information on whether these therapods grew to such sizes.  However, there also not enough information ruling out such massive sizes.  A 12 metre abelisaurid would be an amazing thought, but the closest we came to see that was in Disney's Dinosaur and Jurassic World...

The problem with Titanovenator is that it only has a brief and vague extract to describe it. It doesn't even explain how the 11-12 meter estimates were reached. Errachidiasaurus and Libyacolossus both have papers describing them, and explain how their estimates were calculated.
