Corrected entry: How did the mosasarurus survive that long without food? I know the writer of the film says this part takes place a week after the first movie but that's not true. The remains of the Indominus Rex are just a skeleton, that takes a lot longer than a week. And the mosasarurus could have been feeding on it, but then the remains wouldn't have been intact.

Jurassic World: Fallen Kingdom (2018)
Correction: Colin Trevorrow says the beginning of the film takes place between a week or a month, not necessarily a week, also it could've eaten the Indominus rex slowly or any pteranodons that flew to close to the surface, it was already freed for 2-3 years when Fallen Kingdom actually starts.
Correction: It could have fed on the other dinosaurs roaming the park that came too close to its lake.
