What is confirmed: The official Roblox description says bigger boats reach new fossil islands. It also mentions fishing, diving, a Sunken Grotto and a group Mosasaurus fight. We have not independently checked shop costs, speed or every island unlock in-game.

Trying to reach your next fossil island? First work out what is stopping you: travel or digging. The official game connects bigger boats with new destinations. Community shovel guides describe separate equipment tiers for digging. Buying one kind of upgrade does not necessarily solve the other problem.

Boat or shovel: what should I upgrade first?

IF YOU CANNOT REACH THE ISLAND

Consider your boat

Check the dock or current in-game boat shop. The developer says bigger boats can reach new fossil islands. Verify the actual access requirement before spending coins.

IF YOU ARRIVE BUT CANNOT DIG

Check your shovel

Community equipment records connect shovel tiers with fossil periods. Compare your tool against the current site and any restriction shown by the game.

Plan your next boat trip

  1. Choose a destination: locate the fossil island you want to explore.
  2. Check travel access: if the route needs a larger boat, inspect the in-game dock shop.
  3. Check digging access: compare the site with your shovel and any live requirement.
  4. Set a coin target: enter the price shown in-game in our coin budget planner.
  5. Finish a fossil set: bring the missing fossils back to Dr. Ivy’s DNA Lab before chasing every upgrade.

How much does a boat upgrade cost?

DATED COMMUNITY EXAMPLE4,000 CoinsOlder report for an early boat upgrade — not confirmed in-game here.

This amount appears in an earlier community guide; names, prices and speed may change. Use it as an example only. Enter the actual quote from your Roblox session in our planner.

What can you do in the ocean?

The developer mentions the following activities. This does not mean we have measured the odds, captured these locations ourselves, or verified every ocean route.

Fish and dive

Look for catches in the open sea. The official description does not include a complete fish list, gear costs or catch rates.

Sunken Grotto

The game describes sneaking in to take sea reptile eggs. Exact location, entry conditions and egg handling still need live confirmation.

Mosasaurus encounter

The official listing describes teaming up to fight a giant Mosasaurus with spears. Exact health and rewards are not documented in that listing.

Frequently asked boat questions

Does a bigger boat make my shovel stronger?

No such effect is stated in the official game description. Boats are discussed as travel upgrades; community equipment lists separately describe shovel access. Always follow the current in-game requirements.

Can a dinosaur replace a boat?

The game says Elder dinosaurs can be ridden, but does not promise that every creature can cross water. Some community reports discuss aquatic mounts; we have not tested which work in the current release.

How do Sunken Grotto eggs hatch?

The official description confirms sea reptile eggs there, but does not state that their handling is identical to eggs made from fossil sets at Dr. Ivy’s lab. Follow your in-game instructions.
