Teranosaurus Rex vs Brontosaurus

Teranosaurus rex versus brontosaurus. Who wins? In it depends on the circumstances. Brontosaurus was actually such a mass of creatures that they could actually use their tails like whips. They were so mighty that things didn't go after them one on one. The teroe, i assume, sir. I assume this was an amfering. Er, oh, yes. But classic fight. A terex would not necessarily go after a brontosaurus, but it might go after a couple o little baby ones if you put em in an octagon and they had to go at it.
