FossilForge

Become a paleontologist. Dig a fossil out of the rock, clean it, rebuild the skeleton, and figure out what it was — then learn to read the story written in Earth’s layers, all the way back through deep time.

Dig & investigate

Four hands-on paleontology surfaces — every one is something you do, not just read.

🦴 Dig Lab Run a real dig on a fossil from a famous site: excavate it from the rock, clean it, rebuild the skeleton, then identify what you found. ⏳ Deep Time Order the eras of Earth’s history — then learn to read rock layers, so you can tell which layer is older just by looking. 🌳 Cladogram Lab Build the tree of life — arrange animals by the features they share to see how one group evolved into the next. ⚛️ Decay Lab Predict how a radioactive isotope fades by half-life, then read a fossil’s age from how much is left — the real math behind radiometric dating.

Practice the concepts

16 kits from “what is a fossil?” up to advanced synthesis — a short round of questions with a hint whenever you get stuck. Your progress stays on this device.

Play together

Go head-to-head with a friend — same device or an online room.

FossilForge Duel (pass-and-play) 2–4 players take turns on one device — same questions, highest first-try score wins. Or open an online room to play a friend on another device. FossilForge Journey — follow the map → A path through every kit. Clear each stop, then move on — see how far you’ve come.

Mixed practice

Mixed practice — revisit what you've learned A short round that shuffles questions from the kits you've played, brought back when they're ready to review. Great for making it stick. FossilForge Sprint — a calm speed round → Once you’ve mastered a few kits, race your OWN best on what you already know. Timer optional, no penalty for a miss.
