The Sims 4: Fossils (Collectible) - Ultimate Sims Guides (2025)

Fossils are just one of many collectibles in The Sims 4 and can be found in all of the worlds in the game by digging up rocks. When you finish your fossil collection you’ll be rewarded with a special plaque to commemorate this wonderful accomplishment.

Traits That Help With Collecting

Since your sim is going to be outside looking for fossils, they should definitely consider the loves the outdoors trait. Sims with this trait are going to enjoy spending time outside more and will see a smaller decrease in their motives when they are outside.

You could also give your sim any of the Nature Aspirations because this will give them the collector trait, this trait helps your sim find more rare collectibles on a more consistent basis which can help you find fossils.

Where to Find Fossils

The fun thing about fossils is that you aren’t just going to dig up a fossil when looking under rocks for collectibles. They aren’t there! You will dig up a piece of limestone that will go straight into your sims inventory.

From here, you’ll be able to click on the limestone in your sim’s inventory and extract the fossils. Beware however, some of the fossils are going to break and not be worth nearly as much money.

Rare fossils are more likely to be found by going to Sixam, the special alien planet that you can visit by building a rocketship and installing the wormhole generator.
