NGSS.4-ESS1-1

This type of fossil forms when sediments bury an organism and then sediments change into rock; the organism decays leaving a cavity in the shape of the organism.

• mold
• cast
• petrified
• trace

NGSS.MS-LS4-1

This type of fossil forms when minerals soak into the buried remains, replacing the remains, and changing them into rock.

• mold
• cast
• petrified
• preserved
