One would think that if you were in a submarine while it was submerged, you’d be safe from most of the dinosaurs. Still, since Kevin Layne’s character and the other submarine operators are supposedly being surrounded by dinosaurs in the scene, it’d be wise not to bet money on the T-Rex or another one of these land-based terrors not finding a way to attack. Plus, as we saw in 2015’s Jurassic World, Isla Nublar has at least one ancient creatures that’s swimming around, the Mosasaurus. Maybe it’s this creature that tries to kill the submarine crew. The question then is if they can fire off something that can kill it or if they’ll be devoured despite being surrounded by a thick hull. I can’t help thinking it will be the latter.
