Megalodon vs Mosasaur

[Zoom]

After watching Jurassic World, the Indominus Rex and Mosasaur looks like bad asses. Anyway, how well Mosasaur faced off against a Megalodon?

The JW mosa was 60ft if I recall, which is right around the Meg's general estimates. I want to say the Meg because I'm a fanboy (love the mosa too), but I'm not sure.
