English field notes from a real game session. We inspected the official Prehistoric Farm experience on October 11, 2026 using a level-1 player account. Screens recorded in a non-English client have been withheld from this English-language website. These are clearly marked English editorial summaries, not recreated game screenshots. Observations may differ for other players or after an update.
Fossil sets: what we observed in the game
The fossil collection menu showed nine sections. The first three are a useful basis for the wiki’s 34-entry community mini-catalog, but that mini-catalog is not the complete game roster. The menu slot totals do not establish the names, identities or rarity of 101 unique species.
Fossil-piece requirements
These numbers were read from the in-game collection menu. We checked the visible entries in these three sections; later-era set requirements have not been confirmed.
All nine sections shown in the collection menu
| Collection section | Slots shown | Fossil requirement | Evidence scope |
|---|---|---|---|
| Cambrian | 6 | 4 pieces | Observed |
| Devonian | 8 | 4 pieces | Observed |
| Triassic | 20 | 3 pieces | Observed |
| Jurassic | 20 | Not checked | Slots only |
| Cretaceous | 20 | Not checked | Slots only |
| Late Cretaceous | 5 | Not checked | Slots only |
| Panthalassa | 16 | Not checked | Slots only |
| Ancient Skies | 5 | Not checked | Slots only |
| Legendary | 1 | Not checked | Slots only |
Correction: an earlier community source listed five fossil pieces for Cambrian and Devonian. The live menu displayed four pieces for each visible entry in those sections. We updated the wiki’s mini-catalog and the personal fossil tracker to match the session we inspected. Locked creature names and rarity are still community-reported, not independently verified.
UICHANGES code: our single test result
We opened Menu → Settings → Codes, entered UICHANGES, and submitted it once. The game rejected it with a message translating to “Code not found (or expired).” This does not distinguish a nonexistent code from an expired code, and it does not guarantee the same result for every account. No reward was received in that session. The other listed codes were not tested by us.
UICHANGESNot acceptedTranslated game response: “Code not found (or expired).” This is an English observation summary, not an image or imitation of the game’s settings screen.
Compare all reported codes →What we could confirm on the starter-island map
The world map showed Home Island and several unexplored destinations marked with question marks. We could not verify a precise unlock sequence, sailing time, current boat price or the next required shovel from that initial account.
Travel facts we can stand behind
Keep the difference between what the map showed and what community guides claim.
Dinosaurs and the starter merchant
The Dinosaurs menu showed 0/8 on the ranch and 0/60 in storage. We did not yet own or photograph any dinosaur models in this account, so our species illustrations remain labelled as scientific reference art, not game models. We also reached Kiko the Merchant on the starter island, but this encounter did not establish current shovel prices.
How we preserve evidence without misleading images
The original screen captures are retained locally in the research archive, with their session date, location and translation recorded. We do not publish the non-English screenshots on the English site, silently replace their labels, or substitute someone else’s gameplay screenshots as ours. The official game’s public Roblox page is the primary source for general gameplay instructions; the observations above are our own single-session checks. This site is independent and not endorsed by Project Mirvy or Roblox.
