Prehistoric Farm Red Jasper: What It Is and How to Get It for the Silver Shovel

Red Jasper is a digging material in Roblox Prehistoric Farm — not the real-world gemstone. Its designated source is Devonian Island, the second island in the dig progression, and it is one of the two materials you must gather for the Silver Shovel upgrade: 5 Aquamarine Shards from Cambrian plus 8 Red Jasper from Devonian, alongside an 8,000 Coin purchase. Here is the full route from empty pockets to a Silver Shovel in hand.

What Red Jasper Is Used For

Red Jasper's role in the progression is the Silver Shovel recipe at the shovel upgrade spot:

The payoff is progression: once owned, a silver or better shovel breaks the Triassic rocks you need for Clara's quest. If you're still learning the dig loop itself, the fossil excavation guide explains how digging works from the first swing.

Where to Find Red Jasper

Red Jasper comes from the dig spots on Devonian Island. To get there, sail from your current island — ships are the game's cross-water transport — and follow the bearing shown at the top of the screen. In one recorded run, the player steered toward Devonian at 135 degrees after leaving Cambrian. The fossil islands guide covers reaching each island, and the dig sites page shows how to find and start a dig spot once you land.

How to Collect the 8 Red Jasper

You don't need the Silver Shovel to gather its own materials — Devonian's dig spots work with your current shovel. In fact, digging comes first no matter what, because the Silver Shovel purchase stays locked at the upgrade spot until you've gathered the required materials.

A few things worth knowing while you farm:

• Results vary from dig to dig, and a spot can often be dug twice before it disappears, so don't walk away after a single dig.
• An equipped dino can help you dig.
• Expect a grind. One player reached 71 digs on Devonian in a single session before upgrading. There's no established per-dig rate for Red Jasper, so treat your count as luck rather than a schedule.

If you want more out of every swing, the digging timing guide breaks down how to time the dig meter for a better find.

Buying the Silver Shovel

When your materials are stacked, head to the shovel upgrade spot. The purchase costs 8,000 Coins, and while anything is still missing, it stays locked — the screen shows which material you need and how many, which makes it a handy tracker for your remaining Red Jasper. Hand over the materials and coins, and the Silver Shovel is yours.

From there, Triassic opens up: with silver or better equipped, you can break Triassic rocks and continue Clara's quest. Short on Coins before the purchase? A quick check of the current Prehistoric Farm codes can help top up, and the shovel guide covers getting and digging with your shovel in more detail.
