Continuity mistake: When the mosquito is sucking on Dr. Marshall's neck, it keeps changing positions from higher up on his shoulder to more towards the front between shots. This is clear by watching the legs of the bug going from in front of his shoulder to being over the strap even when his head isn't moving.jerimiah
Continuity mistake: When the team lands on the pile of bones, there is some sort of yellow stuff holding it together. The pile is also flush up against the sides of the cave. When the Vines grab them and its a far away show, the yellow stuff disappears and is now a loose pile of bones that's no longer flush against the cave sides.jerimiah
Continuity mistake: The skins that Dr. Marshall and Will find when they go to rescue Holly are out of proportion and don't even look close to how the rest of the sleestak are shaped. Even though it was a "shed skin" - it doesn't even have the same patterns on the legs and arms as the real ones.jerimiah
Continuity mistake: When Holly is translating Chaka's talk with Will around the campfire, we see the closeup shots of Holly showing her right hand holding the bottom of her notebook while she is writing in it. In the closeup shots of Chaka and Will, her hand is up underneath the book curing over the top.jerimiah
Continuity mistake: When Rick Marshall douses himself with dinosaur urine, the amount on his shirt changes between shots.
Continuity mistake: When the dinosaur slobbered on everybody in the cave, they were covered in heavy slime. In subsequent shots, with no time or means for anybody to clean up, the slime was almost entirely gone.
