The Good Dinosaur

In an alternate history, the asteroid that would have caused the extinction of the dinosaurs 65 million years ago passes safely over Earth. Sixty-five million years later, Apatosaurus farmers Henry and Ida have children Libby, Buck, and the runt Arlo, who has trouble adjusting to farm life. While his successful siblings are allowed to "make their mark" (a mud-print on the family's corn silo), Arlo's timid nature makes tasks difficult for him. Henry attempts to give Arlo a sense of purpose by putting him in charge of guarding their silo, and helps him set a trap. It captures a feral cave-boy, but Arlo doesn't have the heart to kill him, and sets him free. Disappointed, Henry takes Arlo to track the cave-boy, leading them into a ravine. Henry saves Arlo from a flash flood before being swept away and killed..
