Acrocanthosaurus atokensis, slightly reworked from my decade-old version. Restored/broken neural spines are now more conservative (and almost certainly more accurate) in height, rather than imitating the BHI reconstruction of the "Fran" specimen. I also redrew the arm to reflect more recent data.

Yay better arm! I'm glad to see this guy redrawn, he's one of my favorite skeletals.
:iconcoolislandsong:
such an awesome animal, you certainly do it justice.

Very nice work :). Although, I rather like the idea of Acrocanthosaurus Atokensis being a member of the Carcharodontosaurida. What about you?
:iconshartman:
I think the idea is interesting (I first heard Phil Currie float it over a decade ago) but functionally Acrocanthosaurus is a lot more like Allosaurus and Sinraptor than like Carcharodontosaurus and Giganotosaurus. Of course function notoriously doesn't always match phylogeny, and it could simply represent different hunt specializations for different environments.

I'm looking forward to future papers to see if the clade holds up.
:iconthearchosaurking:
Hmm, well that makes sense. I do see more of Sinraptor in your skeletal of Acrocanthosaurus.

But, I‘ll use Saurophaganax as an example. But Saurophaganax has been kicked out of the Allosauridea and reclassified as a Sinraptorid. And its now believed that Carcharodontosaurids arose from the Sinraptorids. So, maybe Acrocanthosaurus along with Saurophaganax, are transitional between the Sinraptorids and Carcharodontosaurids.
