Everything in Prehistoric Farm starts with a hole in the ground. You dig fossils on islands, complete a set, and that set becomes an egg at Dr. Ivy’s DNA Lab. No digging, no dinosaurs — which makes the dig meter the single most leveraged mechanic in the game.
The one rule we can quote
The official description is specific about exactly one piece of technique: release the dig meter in the green for a better find. That is the whole published instruction, and it is worth reading it precisely.
It establishes that digging is a timed input rather than a hold-to-dig action, that the meter has a marked green region, and that hitting that region changes the outcome in your favour. It does not establish how much better the find is, whether the green band moves, whether tools change it, or whether there is an extra bonus for the exact centre.
Practise the release
The real meter’s speed is unpublished, so this trainer does not model it. What it does model is the skill: a marker moving across a band you have to release inside. Set a speed that feels like your game, shrink the band until it is uncomfortable, and drill it.
Green-zone release trainer
Practice tool, not game dataStart the sweep, then release while the marker is inside the green band. The band moves every round, so you cannot memorise it.

The trainer needs JavaScript to sweep. The idea still holds without it: the dig meter fills, and you want to let go while the indicator is inside the green band rather than riding it to the end.
Two minutes here is worth more than reading another paragraph. The band repositions every round, so you are training reaction rather than muscle memory for one spot — which is the transferable version of the skill.
Dig smart, not just accurate
Accuracy is one lever; the others are about what you dig for and for how long.
Finish sets, do not collect bones. The DNA Lab works from a complete fossil set. A set that is one piece short is worth exactly nothing until that piece arrives, so a run aimed at closing one set beats a run that advances three.
Dig where the set is. As the game opens up — bigger boats and new fossil islands — you gain choices about where to spend a session. Until you know what each island yields, treat your first visit to a new one as reconnaissance rather than as a farming run.
Know your own throughput. How many digs fit in the time you have is a number you can measure in one session, and it tells you whether a long trip is worth it.
Digs per session, from your own timing
Time one complete dig, including walking to the next spot. No game data is assumed.

What is not in this guide
Shovel upgrade costs, island unlock prices, fossil rarity tables and the drop list for any specific dig site. None of it has been published, and all of it is the sort of thing that gets invented confidently on new-game guides. The shovel page explains what we would need before putting numbers on an upgrade path.

Questions
Frequently asked questions
What does the green zone do when digging?
The official description says releasing the dig meter in the green gets you a better find. It does not define what better means — a rarer fossil, more of them, or faster digging are all possible and none is confirmed.
How fast does the dig meter move?
Unpublished. It may also vary by tool or by island. The trainer on this page lets you set your own speed precisely because we cannot tell you the real one.
Is there a perfect-release bonus?
Not stated. The description distinguishes green from not-green, not centre-of-green from edge-of-green. Aiming for the middle is still the right habit, because it is the cheapest way to stop missing.
