Dig Lab Run a real dig on a fossil from a famous site — excavate, clean, rebuild the skeleton, then identify it. 
Deep Time Order the eras of Earth’s history and read rock layers — tell which layer is older just by looking. 
Cladogram Lab Build the tree of life — arrange animals by shared features to see how one group evolved into the next. 
Decay Lab Predict how an isotope fades by half-life, then read a fossil’s age — the math behind radiometric dating. All activities
Dig & investigate
Dig Lab Excavate a fossil from the rock, clean it, rebuild the skeleton, then identify what you found. Deep Time Order the eras, then read the story written in Earth’s layers. Cladogram Lab Arrange animals by the features they share to build the tree of life. Decay Lab The real math behind radiometric dating — predict the half-life fade, then date the fossil. Teach the Cast Teach a paleontology idea to a cast member still learning it — teaching makes it stick.
Practice & play
Mixed Practice A short round across the kits you have played — brought back to make it stick. FossilForge Sprint Race your OWN best on what you already know. Timer optional, no penalty for a miss. Trick Questions Brain-teasers with a twist — spot why the obvious answer is a trap. FossilForge Duel 2–4 players take turns on one device — same questions, highest first-try score wins. Or open an online room. Progress Your levels, streak, and how each skill area is coming along — saved on this device. Progress report For grown-ups — a private on-device snapshot mapped to the skill areas. Export a CSV or print.

Meet the cast — the characters who teach this
-
Seam Taxonomic + fossil-type classification — family-resemblance-matching (what KIND of organism?) -
Span Deep-time + geological chronology — scale-of-scales (WHEN did this organism live?) -
Branch Morphological adaptation + evolutionary change — branching-not-laddering -
Field Paleoenvironment + ecosystem reconstruction — fossils-as-a-place-story -
Last Mass extinctions + extinction-event reasoning — witness-and-choose (cross-app cameo with EcoSphere Brink) -
Blank The incomplete record — the fossil record is a story with most of its pages missing -
Guise Convergent evolution — unrelated creatures arriving at the same outward form -
Imprint Trace fossils — fossils of behaviour not bodies: footprints, burrows, trails -
Seep Fossilization — how a living thing rarely becomes a fossil: quick burial, slow mineral swap -
Underframe Homology — the same underlying skeleton, in the same order, beneath different forms
