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.

What is the primary condition for the formation of imprint fossils?

• The organism must be preserved in tar.

• The organism must be trapped in amber.

• The organism must leave a mark in soft material.

• The organism must be buried in ice.

Which of the following is an example of fossilized remains?

• A dinosaur bone turned rock-like

• An insect trapped in amber

• A fish preserved in ice

• A leaf imprint in rock

What is petrified wood?

• Wood that has been burned

• Wood that has turned into stone over time

• Wood that is covered in sap

• Wood that is buried in sand

How can insects become completely preserved fossils?

• By being buried in mud

• By being trapped in liquid sap that hardens

• By being frozen in ice

• By being covered in volcanic ash

What happens to animals that fall into sticky tar?

• They are eaten by predators

• They are quickly buried and preserved

• They decompose rapidly

• They turn into coal
