I say nay to you. NAY! Because I didn't care for this movie, allow me to retort and then defend the mistakes in all the other films.
The Mosasaur was a coastal hunter that fed near the surface, so it would have stuck close to shore to prey on sea turtles, seals and sea lions, sharks, and surfers.
It's favorite meal, the Great White Shark, is also a coastal hunter which roams up and down the western coast of North America where Moses was released, so it has ample food near the shore in one of the busiest waterways in the world, especially around California.
It's also been accustomed to being around humans and machinery, so it would have no fear of humans or boats and would probably steal fish right out of the nets in bulk.
It also likes to show off by jumping out of the water and even onto land briefly to go after incredibly large and dangerous prey, eats submersibles whole, and eats guys dangling from helicopters in the middle of storms right after feasting on juicy subs, so it's got an insatiable appetite.
Sucker's getting seen.
But still, impeccable timing of it to wait two and a half years until the big closing montage before finally chowing down on some free range surfer. Good things come to Mose who wait.
- There's actually a thirty foot deep barrier moat around the T-rex paddock (to separate it from the herbivores), perpendicular to the electric fence, that the truck falls into in the novel. You can actually see where the electrified fencing ends just in front of the tunnel in the movie, which would mean the Rex could escape if the ground was level with the fencing there. The movie didn't do a good job of making it clear, and you might have to fudge the details a bit on the placement of the SUV relative to the moat, but it's got some backup.

- In The Making of the Lost World art book, there was concept art of a Raptor standing in a pool of water at the end of a metal corridor about to attack a person with a flashlight, which is possibly supposed to depict how the crew of the Venture was killed, but the scene was never filmed. Although you can deduce as much in the film by the fact that the crew on the bridge was killed by an animal(s) small enough to fit through the doors but big enough to tear a bunch of sailors to shreds. So Blue might not have been the first Raptor on the loose in California.
- At the end of
The Lost World, a naval blockade is established around Isla Sorna now that the island is a nature preserve. It wouldn't be fast or densely picketed enough to prevent small planes or small fast-moving boats like the para-sailer boat that got the idiot and the kid stranded from getting to the island, but it's there to prevent large scale dinosaur poaching and theft operations, or to provide rescue, hence the presence of the heavily armed amphibious Marine detachment and helicopters nearby in
