The reading roadmap —
ages 3 to 10.
Prehistoric Planet isn’t a single book or series — it’s a universe that expands in step with your customers’ children. Picture books become illustrated stories. Illustrated stories become chapter books. And the Dossora Program ties every stage together.
Picture Books
Dino Defenders & Mean Mammals
The entry point to Prehistoric Planet. These books introduce the core cast of characters and establish the central conflict between the Dino Defenders and their rivals in a format even very young readers can engage with fully.
Bold, Instantly Lovable Characters
The Dino Defenders and their Mean Mammals rivals are designed to make an immediate impression — big personalities kids can pick a side on after just one read.
Short, Read-Aloud Friendly
Pacing and language are built for storytime. Parents can finish a book in a single sitting, while kids beg to hear it again.
The Hook for Everything That Follows
Every character and location introduced here pays off in later books. What feels like a standalone picture book is actually the foundation of a universe.
Illustrated Books
Lore & Backstory Series
The bridge between picture books and independent reading. These titles expand on the characters and world children already love, rewarding loyal readers while being fully accessible to newcomers who are ready for a longer, richer story.
Where Lore Comes Alive
These books answer the questions the picture books create: Where did the Dino Defenders come from? What drives the Mean Mammals? The world starts to feel lived-in.
Same Characters, Deeper Stories
Kids who bonded with characters in the picture books meet them again here — older, tested, with more at stake. It rewards loyalty to the series.
Rich Illustrations Throughout
Dense, high-detail artwork keeps younger readers visually anchored as the text grows more complex. The transition to longer books feels natural, not daunting.
Chapter Books
Dino Detectives
Prehistoric Planet opens its doors to a new set of investigators. The Dino Detectives series introduces fresh characters, new locations, and longer mysteries — all grounded in the rules and lore kids have been absorbing since their first picture book.
Independent Readers Take the Lead
The Dino Detectives series is structured for kids reading on their own. Chapters are short enough to feel achievable, long enough to build real narrative momentum.
Fresh Faces, Familiar World
New investigators and settings keep the series surprising, while the underlying rules of Prehistoric Planet remain consistent. Kids feel like experts in the world.
Mystery and Teamwork at the Core
Every case involves a puzzle that requires multiple characters' strengths to solve — reinforcing the series' core message that smart collaboration beats going it alone.
The Dossora Program
Interactive Missions & Collaborative Play
The Dossora Program isn’t a book format — it’s the connective tissue of the entire universe. Running alongside every stage of the reading roadmap, Dossora gives families missions, puzzles, and collaborative activities that bridge the gap between finishing a book and starting the next one.
Missions That Span All Stages
Dossora activities are calibrated to the child's current reading level, so a 4-year-old and a 9-year-old sibling can participate together in different ways.
Reading Time Becomes Doing Time
Puzzles, field missions, and collaborative challenges tied directly to the books transform passive reading into active engagement that parents can join.
The Reason Kids Come Back
New missions drop alongside every release, giving enrolled families a reason to visit your store not just when they finish a book — but on a regular schedule.
Every stage is a reason to come back to your store.
Most children’s book lines produce a hit title and stall. Dino Defenders is architected from the ground up as a multi-year reading journey — meaning a family that finds you through one book has years of follow-on purchases ahead of them.
Years of repeat customers
A family that discovers you through a picture book at age 3 has seven more years of purchasing ahead of them — if you carry the full range.
A clear recommendation for every age
Your staff never has to guess. Point to the roadmap and every customer can immediately see what their child is ready for — and what's coming next.
One universe, zero orphaned titles
Every book cross-references the others. A customer who loves the chapter books will want to fill in the picture books — and vice versa.
