Acrocanthosaurus atokensis v African Bush Elephant

I would say 50/50 for now considering they are both the same size and both have effective weaponry to take each-other out. The elephant is incredibly bulky and a compact body with tusks that can grow 7 feet long but the Theropod has a large powerful arms and a 1.3 metre long skull with certain weaponry advantages due to the elephant's anatomy like the elephant has a lot of fleshy bits that the theropod can make the animal bleed out from so I say 50/50 for now.

Definitely 50/50 though I'm leaning toward the acro a little bit
