This is a dino from the Additions Ascended: Acrocanthosaurus mod

Level 268

Appearing much larger than expected, Acrocanthosaurus is a fearsome carnivorous theropod. While larger than a Rex, it's not quite as strong. However, Acros' seem to demonstrate much stronger attacks the smaller their target is. In addition to this, when an Acro begins receiving damage, Acro resort to an interesting tactic which involves revealing the larger sides of their bodies, mitigating the damage they receive considerably. If they remain in this state the Acro seems to undergo a terrifying enraged state... so be careful. Normally being slower than a Rex, this rush of adrenaline will make an Acro frighteningly fast!
