The Life Size Dinosaur
According to Production Designer Harley Jessup, the filmmakers did a deep dive into what’s known about the size of a real Apatosaurus in an effort to add authenticity to Arlo and his family. “We created a life-size printout of Arlo to help imagine his gigantic scale,” says Jessup. “Arlo is 18 feet tall and weighs about 6 tons, and Poppa, at 46 feet, is taller than the Steve Jobs Building on Pixar’s campus. We exaggerated the size of the T-Rexes for our story, and they range from 38 to 50 feet tall, with Butch weighing in at about 45 tons.
The last to hatch among his siblings, 11-year-old Arlo has yet to make his mark on his family’s farm. Though he is eager to help out with chores, this sheltered Apatosaurus just can’t seem to get past his fear of everything.
Spot is a wild, tough and tenacious human boy who has lived alone in the wilderness for much of his life. He speaks in only grunts and growls, but his strengths are clear: he’s fearless
Brave and selfless, Poppa is a devoted husband and father, working tirelessly to make a life for his family on their farm. He has a soft spot for Arlo, his small and fearful son, and takes special care of him as he grows up.
A loving wife and mother, Momma is smart and quick-witted. She’s a hard worker with a lot of love for her family, and she keeps her children and their farm in order. Her quiet strength is the backbone of the family.
Buck & Libby
Buck is Arlo’s brother: they’re the same age, but Buck is bigger, stronger and a little rambunctious. Arlo's sister Libby is a capable and willful girl who can plow a mean field.
“We wanted Buck and Libby to be more capable, more brave than Arlo,” says Story Supervisor Kelsey Mann. “Everything comes more easily, despite the fact that they’re all the same age.”
Pet Collector is a mysterious Styracosaurus who lives in the wilderness. Like Arlo, he harbors unreasonable fears. His ability to blend into his surroundings helps—along with an unusual (but not exactly fierce) collection of forest critters he’s recruited to protect him.

Nash & Ramsey
Nash, who isn’t the sharpest of spurs and has trouble keeping track of their herd, exhibits a mischievous charm and positive attitude that makes him good company out on the range.
Ramsey loves the challenge of driving a herd of longhorns with her father, Butch, and her little brother Nash. Ramsey has a lively, outgoing personality—she likes good jokes, tells a mean story and has a soft spot for those in need.
The Pterodactyls are a search-and-“rescue" team of five. They like to sit back and let the often-treacherous storms in this part of the world do their dirty work, then reap the benefits of the devastation.
Raptors prey on the prized herd of longhorns that belong to Butch and his Tyrannosaurus Rex family. Raptors—or Rustlers, as Butch calls them—sport wiry, feathered bodies and hardly compare in size or strength to a T-Rex. But as a group, the Raptors pose quite a threat, and even a T-Rex may need to call in reinforcements before tangling with them.
