Visible crew/equipment: When Dr. Grant discovers the eggs in the wild, the camera comes down a tad bit too far. The operator obviously notices because the shadow of the camera creeps in along with the shadow of wires attached to it. To correct this, the shot pans up a bit.

Jurassic Park (1993)
21 visible crew/equipment mistakes - chronological order
Directed by: Steven Spielberg
Starring: Samuel L. Jackson, Jeff Goldblum, Sam Neill, Richard Attenborough, Laura Dern, Wayne Knight

Continuity mistake: When Tim and Lex first arrive, Lex is wearing a purple tank top with a colorful design, and in the following scenes or even between consecutive shots her tank top changes to completely different designs, though it's the same style of tank top.
John Hammond: All major theme parks have had delays. When they opened Disneyland in 1956, nothing worked, nothing.
Ian Malcolm: But, John, if the Pirates of the Caribbean breaks down, the pirates don't eat the tourists.
Trivia: To make the water in the glass on the dashboard 'jump', they strung a guitar string from the underside of the dashboard to a bolt on the floor and then plucked the string.
Question: Are the people present at the digging site when they're discussing new approaches to analyzing skeletons supposed to be paleontologists in dr. Grant's group? If so, why would they laugh at his musings of "how dinos learned how to fly"? And why would he have to explain it to them? Seemed to me like he is explaining very basic stuff to the people that would already know this (and of course, to the movie audience).





Answer: They are not paleontologists, just people interested in dinosaurs. It is common for museums and other scientific organizations to offer the general public an opportunity to participate in a real paleontology dig. For a fee, they become an exhibition team member for a period of time, learn about dinosaurs, help excavate fossils, and so on. This is likely how Dr. Grant (or his institution) supplements his research funding.
