The safari guides and hunters traveled about 60,200,055 years into the past, where they focused on killing the ferocious Tyrannosaurus rex. They believed that killing them would ensure that the natural order was not disrupted as identified and spotted by the previous safari guide. Since Eckels lacks hunting experience, he offered as much as ten thousand dollars to anyone who kills a dinosaur.
During this period, Travis organized and led the safari guide, where he emphasized the maintenance of safety measures, such as remaining on the path. In the journey back to the last time when dinosaurs existed, Eckels found wonders but took it lightly and underestimated the difference between the modern world and the long-ago past. Although he was supposed to consider the experience seriously, he took it just as any other activity and eventually made deadly mistakes.
