Billy Brennan

Billy Brennan was a graduate student in paleontology working for Dr. Alan Grant at the Fort Peck Lake, Montana dig site during and prior to the events of Jurassic Park III. He traveled to Isla Sorna with Grant, The Kirby's and their team. He was believed to be dead when the Pteranodons pecked at him, but we discovered that he was still alive when the marine corps rescued him. He rescued Dr. Grant's hat.
