Greg is a man camping in Big Rock National Park in 2019 when his campground sees an Allosaurus attack. Greg is seen drinking a beer and sitting outside his RV when the family neighboring him is cooking dinner. He tells Dennis, the patriarch of the family, that there will be a meteor show later that night. He hides in his RV when the Nasutoceratops and Allosaurus appear at the campground, but comes back out again when the attack is over. He owns a crossbow, and had shown it off to Dennis’ daughter, Kadasha, earlier that day. Kadasha used the crossbow to chase away the Allosaurus during the attack. Unlike Dennis’ camper, his RV sees minimal damage, with apparently only the awning showing damage.
