The Sims 4 Fossil Collecting Guide

Fossils List and Values

Fossils are found while digging rocks strewn throughout the Sims 4's game world. This collection will take some time to complete due to the fact that you have to collect Metals and Crystals from the same spawners.

See the Collecting Guide for general tips to finding these and other Collections in The Sims 4.

Fossil List

Fossils may be worth up to 20% less than what is listed. All Fossils give a +3 Environment boost to the room they're placed in, which helps with decorated bonuses. Studying a Fossil that has been placed will give a Sim a +1 Focused Moodlet for 4h.

I've found a Fossilzed Mouseosaurus and a Fozzilzed 3 Toed Footprint. Do you think these replace 2 of your list, or are there more to the collection than you found?


If you have the Jungle expansion pack, there are 5 additional fossils: Fossilized Simian, Fossilized Crocodile Jaw, Fossilized Mouseosaurus, Fossilized Llama Toe, and Fossilized 3 Toed Footprint.


I got a fossil that isn’t listed on here:

Fossilized Mouseosaurus, Common, $60 Value, 3 Environment


Yes that is one of the new fossils that came with Jungle Adventure. This collection completes with only Base Game items so we list it that way for people who do not have all the other purchasable DLC.
