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.
