Suggestions for my ultimate predator showdown before I make it?

Megalotyrannus

Making an ultimate predator showdown. Comment on here if you would like your supermassive real carnivorous dinosaur on here. I am using T. rex, Titanovenator, Acrocanthosaurus atokensis, Spinosaurus aegyptiacus, Spinosaurus morrocanus, Carcharodontosaurus saharicus, Carcharodontosaurus iguidensis, Giganotosaurus carolinii, and Saurophaganax maximus. Let me know if there are any others I should include. I will be making the battle two weeks from now so be quick about it if you want to see your favorite large carnivorous dinosaur duke it out with other biggies.

How about a pack of Mapusaurus?

Megalotyrannus

That'd make things interesting as Mapusaurus rosae is extremely large and if they hunted in groups that'd make them really dangerous.

Concur with the addition of Mapusaurus

I also have recently found out about a new species of Tyrannosaurus.  It has been dubbed Tyrannosaurus imperator.  With this only having a 16 year old to represent the species it is really large.  Being 13 feet tall, 51 feet long and weighing a whopping 13 tons he may have a great advantage here.  Should I add it?

It was not 13ft tall 51ft long or 13 tons in weight; T.imperator is synonymous with T.rex.

Megalotyrannus

I looked into it and it is a distinct species.  The differences in the skull make it more like an over sized Tarbosaurus than a T. Rex.

^No, the specimen to which you are referring is UCMP 118742, aka the Peck's Rex. The reason it used to be estimated at fifty-one feet long was because they were stupid and used the bones of a f*cking sauropod. So now it's downsized to 12.2 meters.

Also, it's debatable whether S.morrocanus is the same genus as S.aegyptiacus or if it's an entirely new genus--Sigilmassasaurus brevicollis.
