You said after I faced the T. rex! :-( Also they reckon the spinosaurus wouldn't have hunted in water, but stood on the banks with its nose in the water. It's got hundreds of tiny pressure sensors similar to a crocodile or shark in its snout, and would only have eaten fish. So as long as I stay away from shore, I'd be ok. Just swim to the opposite bank to the spinosaurus. But I guess that leads me to raptor territory...
