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.
