Lucio moves to San Saurio to live with his lively Aunt Laura and attend school, missing his old life in Zamala. Just as he starts settling in, he receives a mysterious call with specific instructions. Suddenly, Lucio is suited up in high-tech gear, dropped into a futuristic vehicle, and propelled through a glowing tunnel.

Lucio speeds through a forest filled with real dinosaurs, accidentally ejecting himself onto a Brachiosaurus. He's rescued by helmeted figures who reveal themselves as Oz, Delby, and Jay Min from his school. They take him to a hi-tech base where he meets Professor Laura-his aunt-who invites him to join Dinoster on Dino Earth.

Lucio settles into his new life as a member of Dinoster, but has trouble keeping it a secret on Earth. On his first real mission with the team, they run into some trouble with a rampaging Triceratops and Lucio learns about his suit's abilities.

Lucio struggles with the side effects of trans-dimensional travel. While leading a herd of Iguanodons, he suddenly teleports into the jungle, where he convinces an Ankylosaur to free his vehicle. Lucio accidentally teleports a battle-armored T-Rex back to his team, forcing Delby to transform her vehicle to protect them. The mission succeeds, but the mystery of Lucio's teleportation remains.

The team is sent into the jungle to uncover the mystery of what's been damaging the ferns. There they encounter a group of prehistoric FROGS who take a liking to Jay Min, but they're not to blame. It's a Saurophaganax with a bad tooth - and it's angry! The team rallies to avoid being eaten by the dino while trying to lure it into a makeshift dino dentist chair and pulling its tooth.

Lucio rescues an egg that hatches into a baby Pterosaur. He tries to keep it secret from Professor Laura, but the baby's mother swoops in and takes both her baby and Lucio! The team launches a rescue mission, but a group of Oviraptors threatens to derail their efforts.

The team goes to Dino Earth to create a music video for a school project. Delby is initially against it, but she eventually comes to enjoy herself - so much so that she puts her life in danger to retrieve their camera when it gets snatched by a rogue Pterosaur!

After rescuing a Brachiosaurus, the team discovers its herd is searching for blight-free leaves. Their mission is to guide the herd to the Green Gully, where food is abundant. The Professor lets Lucio lead, and he successfully uses a branch to direct the herd. However, upon arrival, Lucio finds large traps set to snare dinosaurs. But who left them there?

The base is attacked by a head-butting Pachycephalosaurus, and the team sets up a containment unit while Lucio tries to lure it away. They discover a strange tag on the dino, which soon transforms into a powerful Armorsaur. As more Armorsaurs appear, the team must battle the beasts and figure out who is behind their transformation. Professor Laura might have the answers.

The team heads out to a geyser field to save a baby raptor from the boiling steam geysers. But when the baby raptor turns into an Armor-Raptor, it becomes clear that something else is at play here. After removing the baby raptor's armor, the gang is ambushed by a giant robotic Mosasaurus piloted by a new nemesis.

Lucio tries to smuggle baby Raptor Roddy back to base but is caught by the Professor, who orders Roddy's return to the wild. During the mission, the team is ambushed by an armored Einiosaurus. Roddy distracts it, giving the team time to combine two vehicles into a large robot. After the battle, they take Roddy back to base, hoping to convince the Professor to let him stay.

The team travels to Dino Earth's Snow Valley to seal a glacier crack threatening a Woolly Mammoth colony. Lucio, eager to see snow for the first time, spots a family of Mammoths chased by a Smilodon. He intervenes, but their baby falls into a chasm! As the Mammoths try to help, the Smilodon transforms into an Armor-don. Can Lucio protect the Mammoths until his team arrives?

The Professor sends the team to investigate why Archaeopteryges are circling the forest. They discover a Tarbosaurus and Spinosaurus battling near a nest of eggs. When Lucio attempts to save the eggs, the dinosaurs transform into Armorsaurs and attack! The team is overwhelmed until some Archaeopteryges come to their rescue.
