Boldly and sometimes carefully scrape away the rock and soil to dig up various fossils.

Use your tools carefully to avoid hitting the fossils and remove only the dirt around the bones.
If you hit a bone, your precious research object will shatter!
Boldly hit it with the hammer, carefully scrape it off with the chisel, and clear away the last of the dirt with the brush.
I know it's fun to keep hitting with the hammer, but be careful not to hit too hard.

Dig up ancient fish and dinosaurs buried in the rock to build your own collection.
