Here is a screen used Prehysteria dino egg that I got a year back. It has a rod attached to it. It was used in the scenes where the eggs were in the nest. I'm afraid I don't know which dino the egg went to beacause its been years since I've seen the movie. I was told by the seller that only two of the eggs survived after the movie was shot and he had both of them. Now I have both of them :)
