Fascinating Fossils: Types of Fossils

The video tutorial explains various ways fossils are formed. It begins with imprint fossils, which are created when organisms leave marks in sediment that hardens into rock. The tutorial then discusses how hard remains like bones, teeth, and shells become fossilized. It also covers the process of trees turning into petrified wood and how insects can be preserved in hardened sap. Finally, it describes how animals can become fossilized in tar, preserving their complete skeletons for study.

Explain how insects can become completely preserved fossils.

What role does sticky tar play in the fossilization process?
