Question

which correctly lists three materials that preserve soft tissues in fossils?

amber, minerals, and sediment
minerals, permafrost, and amber
permafrost, amber, and tar
sediment, minerals, and tar

Explanation:

Analyze the requirements for soft tissue preservation

Preserving soft tissues requires preventing decay by excluding oxygen, moisture, and decomposers. This is a specialized form of Fossilization.

Evaluate the materials in the options

• Amber: Tree resin that hardens, sealing organisms and preserving soft parts.
• Permafrost: Permanently frozen ground that freezes and preserves entire organisms.
• Tar: Thick sticky petroleum that traps organisms and prevents decay of soft tissues.
• Sediment and Minerals: Typically replace organic matter, preserving hard parts (bones/shells) rather than soft tissues.

Identify the correct combination

The combination of permafrost, amber, and tar all preserve original soft tissues.

Answer:

• (A) amber, minerals, and sediment
• (B) minerals, permafrost, and amber
• (C) permafrost, amber, and tar (Correct answer)
• (D) sediment, minerals, and tar
