What is a mold fossil?

• A replica of the original organism created by minerals filling in a mold
• A fossil formed when minerals seep into the bones or other tissues of an organism
• An impression left in sediment when an organism dies
• A preserved sign of an organism's activity

What is a cast fossil?

• An impression left in sediment when an organism dies
• A replica of the original organism created by minerals filling in a mold
• A preserved sign of an organism's activity
• A fossil formed when minerals seep into the bones or other tissues of an organism

What is permineralization?

• An impression left in sediment when an organism dies
• When minerals seep into the bones or other tissues of an organism and replace them with hard minerals
• A preserved sign of an organism's activity
• A replica of the original organism created by minerals filling in a mold

• Fossilized animal remains

What are trace fossils?

• Impressions of parts of different organisms
• Impressions left in sediment when an organism dies
• Preserved signs of an organism's activity
• Replicas of the original organism created by minerals filling in a mold
