Continuity mistake: When the car with Tim and Lex is turned over, mud flows into it and it's like they are going to drown. But when seen from the outside, next to the tracks is a firm gravel road, and Dr. Grant doesn't even sink in when he steps out of his car with the flare.

Deliberate mistake: When flying towards the island, the sea in the background is way too close. A helicopter flying over open sea would never fly that low. And when the camera cuts to an external view, the helicopter is also much, much higher.

Continuity mistake: When Grant shoots at the window in the control room, and we see the holes, they are holes from rifle bullets. But the shell casings on the floor is from a shotgun. And yes - shotgun shells do exist with one big slug in them, but then the holes in the glass would be a lot bigger.

Other mistake: The kid who at the dig site in Montana says "That doesn't look very scary" is so far from the screen and behind all the other spectators that he can't possibly see the picture on the screen. And even if he could, it doesn't look anything like a six foot turkey.
