Alan Grant hired a large group of volunteers to assist him with his paleontological dig in Montana. These volunteers helped to operate the computer and Grant relied on their assistance to save money in the absence of funding. He also relied on their work in order to complete his dig within the four summers his dig’s funding was allotted. The volunteers seemed to be of varied ages, from children to adults.
There was also indications that several of the volunteers had signed up without doing much research about dinosaurs or even the books of the man heading the dig. Several of the volunteers seemed to have different positions, such as operating the computer, or informing Grant about the readiness of projects. (As seen in a volunteer lady informing Grant about the computer.)
Most notable among the group of volunteers is a boy who doubts Grant’s statement that dinosaurs are descended from birds, and mocks him. Grant responded by describing the Veloociraptor‘s hunting methods to the boy, which scares him. Grant is later chided by Ellie Sattler for frightening him, saying that he could have used a gun if he wanted to scare him.
