Purussaurus vs Titanoboa

Its the largest caiman vs the largest snake. Both Purussaurus and Titanoboa were apex predators in South America. Purussaurus lived in the Miocene Epoch while Titanoboa lived in the Paleocene Epoch. So these creatures never met but what if they did?

Verdict: I think Purussaurus would win 65% of the time due to its Fighting Experience and Bite Force. But if Titanoboa were to attack Purussaurus by surprise then Titanoboa would constrict the caiman and win. But in a head on fight, Purussaurus wins.
