Prehistoric Farm Fossil Islands: Periods and Home Services

Identify Prehistoric Farm fossil island names, distinguish Home Island services, and separate known periods from unverified travel gates.

The documented Prehistoric Farm island names are Home Island, Cambrian, Devonian, Triassic, Jurassic and Cretaceous. Home Island is the service base; the period islands are fossil destinations. Cambrian is the first fossil island in the opening route.

The gameplay video leaves the home area for fossil islands and returns to the lab. Follow that relationship between destination and service rather than expecting every island to contain every ranch facility.

Separate home services from collection destinations

Home Island has the ranch, dock, DNA Lab, Digby's Shovels and Bramble's Feed. A return visit can serve several purposes: extracting a completed set, checking a hatch, buying an appropriate tool or feeding a creature.

Period names also organize the collection menu. The documented collection counts are Cambrian 6, Devonian 8, Triassic 20, Jurassic 20 and Cretaceous 20. Cretaceous Seas is a separate six-entry fishing egg collection, not an ordinary fossil island Dig Site group.

Check the period your shovel supports

Wooden Shovel supports Cambrian, Bronze adds Devonian, Silver adds Triassic, Iron adds Jurassic and Titanium adds Cretaceous. This is digging access. It does not establish a corresponding boat price or island purchase gate.

The recorded player reaches Triassic and then encounters the Silver Shovel requirement. Getting to the island and being able to use its fossil site are separate conditions.

Plan a destination without inventing a gate

Later map labels can appear as question marks. Exact island prices and required boats are not established here. Use the live map, travel offers and Dig Site requirement for the destination you want rather than assuming the period order is a complete purchase sequence.

Use reaching fossil islands for the journey checks or boats for the travel options. When you finish a creature set, return to Home Island's DNA Lab so the collection trip advances toward an egg instead of remaining only a growing inventory.
