Fossils & Rocks

Complete guide to fossils and rocks in Dig All Dinos — digging, cleaning, combining, selling, and volcanic cave drops.

Last updated:

Fossils and rocks are the foundation of Dig All Dinos by Wrekt Studios. Every amber milestone — tools, zones, dinosaurs — starts with breaking the right rocks and deciding what to clean, combine, or sell. This guide explains item types, zone behavior, inventory rules, and links to fossil rarity tiers and dinosaur income ranks.

Rocks: where items come from

Rocks spawn in dig layers across the map. Interact to break them with your equipped tool — higher shop tiers mean fewer swings per node.

Surface and starter pits drop common rocks with F–C tier fossils — fine for learning controls and first combines.

Mid caves introduce uncommon nodes and longer break times.

Volcanic caves are the community farm focus: deeper breakpoints skew toward B–A fossils with rare S-tier pulls at the lowest reachable layers. Heat-themed visuals mark these zones; bring upgraded tools before pushing depth.

Some rocks yield sellable shards with no fossil — instant Ambers, especially useful when Auto Sell filters junk.

Fossils: states and workflow

Fossils drop uncleaned from rocks. They occupy inventory slots until processed.

  1. Uncleaned — cannot combine; heavy inventory weight.
  2. Cleaned — ready for dinosaur assembly at combine stations.
  3. Combined — consumed into a dinosaur item; passive Ambers begin.

Cleaning without Instant Clean (599 R$) uses manual timing — see platform pages (PC, mobile, console). Instant Clean removes the mini-game but keeps the interact step.

Rarity and what to keep

Fossil rarity is not the same as dinosaur income tier, but they correlate. Use the dedicated fossil rarity S–F list for drop frequency and the dinosaur tier list for end-product value.

Quick rules:

  • S/A fossils — keep for combines; avoid panic selling during inventory panic.
  • B fossils — combine once for stepping-stone dinosaurs, sell duplicates.
  • C fossils — sell during tool rush, combine during collection pushes.
  • D/F fossils — sell immediately or let Auto Sell handle them.

When two guides disagree after a patch, trust recent community reports on updates.

Selling fossils and rocks

Selling converts items to burst Ambers — critical for shovel upgrades early, optional late when passive dinosaur income dominates.

Manual sell at vendors vs Auto Sell pass — the pass saves menu time during long volcanic runs. Misconfigured Auto Sell is a leading cause of accidental rare fossil loss; configure before deep farming.

Compare sell price to opportunity cost: an A-tier fossil part might sell for decent Ambers now but unlock a higher passive dinosaur later.

Combining into dinosaurs

Combine stations accept cleaned fossils matching dinosaur recipes. Completed dinosaurs generate passive Ambers over time — the incremental core of the game.

Plan combines around tier goals, not random inventory clutter. If you are one piece short of an S-tier dinosaur, bank space and label mentally — some players use external checklists from official community links.

Duplicate complete dinosaurs may still help collection score or future trading if Wrekt Studios expands social features — income-focused players prioritize first copy only.

Inventory management

Caps force sells or cleaning trips. Mitigations:

  • Upgrade carry weight in shop.
  • Clean in batches at cave exits.
  • Sell D/F tier before re-entering volcanic zones.
  • Enable Auto Sell only with safe filters.

Mobile players hit caps faster due to menu friction — see mobile controls tips.

Volcanic cave farming checklist

  1. Upgrade tool to recommended tier for target depth.
  2. Review fossil rarity for expected drops.
  3. Empty inventory or expand bags.
  4. Set Auto Sell / Instant Clean if owned.
  5. Farm route → clean → combine → reinvest Ambers.

Fossils and rocks are simple items with deep decisions — rarity knowledge and clean/sell discipline separate fast accounts from stalled ones.

FAQ

Frequently Asked Questions

Quick answers to the most common questions.

What is the difference between rocks and fossils?

Rocks are world nodes you break; fossils are items inside rocks that must be cleaned before combining into dinosaurs.

Should I clean every fossil?

Clean fossils you plan to combine or that are B-tier and above. Sell or auto-sell D/F tier without cleaning when possible.

Where are the best rocks?

Volcanic caves at deeper layers generally offer better fossils. You need upgraded tools and practice with your platform controls.

Can I lose rare fossils with Auto Sell?

Misconfiguration can sell valuable items. Set filters carefully and test on junk before long volcano sessions.

Do fossils stack in inventory?

Each fossil typically occupies a slot. Carry upgrades and frequent sell trips manage space — see shop upgrades.

How do fossils relate to tier lists?

Fossils rank on fossil rarity tiers; assembled dinosaurs rank separately on dinosaur income tiers.
