The last to hatch among his siblings and the smallest, 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. So when Arlo falls into a river and finds himself swept hundreds of miles away from home, he’s forced to face his fear for the first time in his life, braving the harsh, untamed wilderness and a long, arduous journey home. Along the way, Arlo develops an unlikely friendship with a human boy named Spot who helps him realize he is capable of much more than he ever thought.
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. Poppa believes in Arlo and knows that with enough perseverance, Arlo can overcome his fear and make his mark.
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, confident and a survivalist. Spot quickly proves to be a great resource to Arlo, and slowly, becomes a friend.
Forrest Woodbush 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.
Butch is a rugged and intimidating Tyrannosaurus Rex—showcased by the gruesome scar across his face. A veteran rancher who’s a real pro when it comes to herding longhorns, Butch encourages his kids Ramsey and Nash to learn by doing, hurling them into one hairy situation after another. Butch likes nothing better than trading war-stories over a campfire at the end of a long day.
A fearless, whip-smart and no-nonsense Tyrannosaurus Rex rancher, 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.
An enthusiastic young Tyrannosaurus Rex, Nash lives for adventure, and loves when something unexpected breaks up the routine of rounding up longhorns with his father, Butch, and his big sister Ramsey. He isn’t the sharpest of spurs and has trouble keeping track of their herd, but his mischievous charm and positive attitude make him good company out on the range.
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.
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. But when these flying hunter-scavengers set their sights on Spot and Arlo, they’re in for a big surprise.
