The size of Acrocanthosaurus Atokensis

i decided to tackle this because there seems to be a lot of misconceptions and under estimations.

Acrocanthosaurus is a genus of Carcharodontosaurid theropod from the early cretacious. It was the apex predator of its time frame; the largest of the time.

But, how big was it exactly? 

The name Acrocanthosaurus atokensis was first assigned to two very incomplete skeletons excavated from Atoka County in Oklahoma which were described in 1950. Many trackways have been found with what have been described as the footprints of this, extremely elusive killer dinosaur. One well known trackway discovered near Glen Rose Texas shows what appears to be an attack upon a much larger sauropod. Other trackways could belong to other well known theropods, or large ones just waiting to be unearthed. 

As we all know, foot prints can be a terrible way to estimate an animals size.

now onto the actual remains..

In 1983, excavation on a theropod dinosaur began, with Paul sereno at the head. They didn't know what it was, but it was huge, around the length of Tyrannosaurus. The dig took around three years to complete, and yielded a monster.

NCSM-14345, Fran for short. Her skull alone measured 1.3 meters(4.3 feet) long. Estimations put ole' Fran at 11 meters long(35 feet), and around 5 tons.

However....

Being a Carcharodontosaurid, she might have been even heavier. Also, keep in mind that Fran is only the largest discovered, much like Sue in the world of Tyrannosaurus. Two other fragmentary specimens have been unearthed, but estimates have not been put out on them.

Considering the fact Acrocanthosaurus was a sauropod slayer, it would indeed need to be massive. Also, It is unclear if 'Fran' is male or female.

My estimations(based off of fran, and other Carcharodontosaurids) put the average Acrocanthosaurus at 12 meters long and 6 tons. With an absolute max of 14 meters and 7.5 tons.

The truth of the matter is we need more Acrocanthosaurus remains to be dug up, or we will never know for sure. 

Acrocanthosaurus remains one of the largest land based predatory animals of all time, and one that deserves the spot light for a while.
