"*DISCLAIMER*
I know ARK's animals are not supposed to be the real-life creatures, and I love the game regardless of it's inaccuracies. This is merely to show a "what-if" of what it would be like if the ARK team strived for realism in their creatures designs.

REMEMBER WHEN I SAID THE NEXT ONE WOULDN'T TAKE 10 MONTHS?

So..The ARK Bronto sure is something. It's probably one of the worst of ARK's mess ups.
Simply put it's a cartoon of a sauropod given realistic texturing. It's anatomy is so off from the real Bronto the ARK Diplodocus is actually way closer to what it should look like.

ARK's Bronto has too long a neck, too short a tail and too tall of legs. The neck should also be fat, triangular and held horizontally. The ARK Bronto's head is also 110% wrong. The dossier shows a Camarasaurus skull and the actual artwork and model don't resemble either a Camara or Bronto.
Also the spikes along it's back though not present are technically possible (correct me if I'm wrong) but I decided to leave them out.

/Also I just noticed that the rex has been featured in the last three dossiers in the diagrams. I guess it's good practice for when that actually happens/
