Acrocanthosaurus atokensis

Description

The last in my series of giant theropods, A. atokensis.

A massive, basal carcharodontosaur from the Aptian and Albian of North America with a slender body, enlarged spinous processes and, compared to the later, more popular, and somewhat larger Giganotosaurus, a proportionately smaller skull.

The largest specimen of A. atokensis is NCSM 14345 (Currie & Carpenter), estimated as ~11.5m in its description and shown as ~11.8m in skeletal restorations.

It looks cool, I recently made one too, According to my measurements of Hartmans Acrocanthosaurus, the full length was about 11,56 m and size of the skull was 1,29 m.

Now that I think, the 13,7 m figure for Carcharodontosaurus might be more than just a guess, using the 11,56 m figure and the 1,312 m long full skull length, proportioned to a 1,56 m skull then the length estimate is exactly 13.7455121951 m (45.1 ft), surprisingly similar to the figure of Sereno which is about 45 ft (13.716 m).
