Fósiles fascinantes: tipos de fósiles

The video tutorial explains different ways fossils are formed. It starts with impression fossils, which are created when organisms leave marks in sediment that hardens into rock. The video then discusses how hard remains like bones and teeth fossilize, using examples of dinosaur bones and petrified wood. It also covers fossils formed when organisms are trapped in materials like sap or tar, preserving them entirely. The tutorial concludes by summarizing the various methods of fossil formation and their significance in scientific studies.

What is the primary characteristic of impression fossils?

• They are created by organisms being buried in lava.

• They are formed by volcanic activity.

• They are created by organisms being trapped in ice.

• They are formed by organisms leaving marks in soft materials.

Which type of remains are most likely to form fossils?

• Animal fur

• Plant leaves

• Hard remains like bones and shells

• Soft tissues

How do dinosaur bones become fossilized?

• By becoming stone-like over millions of years

• By being buried in sand

• By being frozen in ice

• By being trapped in amber

What is petrified wood?

• Wood that has been eaten by insects

• Wood that has been submerged in water

• Wood that has turned into stone over time

• Wood that has been burned

How can insects become fully preserved fossils?

• By being exposed to sunlight

• By being buried in soil

• By being covered in liquid sap that hardens

• By being trapped in ice
