Prehistoric Farm Boats, Fishing & Sea Exploration

Where should you explore next?

Choose one concrete goal: another fossil set, an open-sea catch or a later sea activity. The developer advertises bigger boats for new fossil islands, fishing and diving, sea reptile eggs in the Sunken Grotto, and a group Mosasaurus fight using spears. The listing establishes these activities, not a complete route or unlock table.

Boats and fossil islands

The official description says to buy bigger boats and sail to new fossil islands. Before a purchase, inspect its current price and what your intended destination requires. This guide does not assume that a larger boat improves every attribute or that buying it removes a shovel requirement.

For a collection trip, identify the set you want to advance and inspect the tools the game asks for at the destination. Keep travel and digging requirements separate. Return to the fossil reference once a set is complete rather than continuing to collect without a target.

Fishing and diving

Project Mirvy explicitly advertises fishing the open sea and diving for rare catches. The public instructions do not establish bait prices, input sequences, catch rates or selling values. Use the live prompts to learn the action, then inspect whether the result matches your goal.

Community footage can help show the setting and interface, but an older recorded result cannot guarantee the next catch. The homepage links Jurassic Dinoz’s recorded session, checked October 12, 2026, as community gameplay. This guide does not derive exact fishing mechanics from its title.

Sunken Grotto eggs

The developer advertises sneaking into the Sunken Grotto for sea reptile eggs. The description does not provide the entrance coordinates, hazards, cooldowns or egg table. Treat this as a later activity to investigate in-game, not a mapped safe route supplied by this wiki.

Ordinary fossil-set eggs are obtained through Dr. Ivy. A Grotto egg should not be assumed to require the same collection recipe; see the DNA Lab guide.

The Mosasaurus encounter

The official listing describes teaming up to take down a giant Mosasaurus with spears. It does not publish health, spear damage, spawn conditions or a guaranteed reward. Check the current encounter instructions and coordinate around what your group actually observes. No solo win strategy or fixed damage calculation is claimed here.

Before leaving the ranch

Inspect any active incubator timer and the belly of dinosaurs you are raising. The official growth rule still matters when planning your attention, but offline growth and timer behavior remain unverified. Use the planning worksheet to choose a trip, then revise your plan from the current prompts.

Sources and scope

Based on the official Project Mirvy experience description, checked October 12, 2026. The instructions establish the main loop, not exact prices, drop rates or timers. This is a source-based guide, not an independently tested playthrough.
