Free animal, dinosaur and natural-history guides
Choose a world. Look closely, compare discoveries and follow their evidence. Each guide connects real tools and source-linked stories, with no account or payment required.
Ocean animals: dolphins, whale sharks and octopuses ↗
Start with a picture, compare three ocean discoveries and follow the evidence.
T. rex vs Velociraptor: compare time, place and fossils ↗
Did T. rex and Velociraptor live together? Compare museum dates, places and feather evidence, then test a dinosaur scene with a timeline activity.
Dodo and mammoth extinction: investigate the evidence ↗
Explore the dodo and woolly mammoth, then investigate what we know about their final chapters.
Animal habitats: tigers, Komodo dragons and bison ↗
Compare tiger, Komodo dragon and bison habitats. Explore how places and adaptations connect, and distinguish reference regions from live sightings.
Explore together or at your own pace.
Use a guide as a conversation starter, a small classroom investigation or a way to explore an unfamiliar animal. Keep one source-supported fact and one unanswered question from each discovery.
