Quizplus · Accepted Answer

Amber, permafrost, or tar are all excellent materials for preserving original organic tissues. Amber is a fossilized tree resin that can trap small insects and other organisms, preserving them in exquisite detail. Permafrost is soil that remains at or below freezing temperatures year-round, which can preserve the bodies of animals and plants that have been trapped and frozen. Tar pits are natural traps that can capture and preserve animals that become stuck in them, resulting in well-preserved fossils.
