17. Ray Arnold's Arm (Jurassic Park)
When Jurassic Park's systems go down, John Hammond and the park's chief engineer Ray Arnold opt to reboot the park's computer and electrical network. Arnold heads to a maintenance shed to complete the process of rebooting the system, while the rest of the group shuts down the park's grid and retreats to an emergency bunker. When Arnold fails to return, Ellie Sattler and Robert Muldoon head to the shed themselves. They discover the shutdown has disabled the remaining fences and released the Velociraptors. Muldoon distracts the raptors outside while Sattler heads to turn the power back on, discovering the severed arm of Arnold who had fallen victim to the raptors on his journey.
