Explorando fósiles: moldes modelos e improntas

The video tutorial explains how fossils are classified based on their formation and preservation. It discusses dinosaur footprints as an example of impression fossils and describes how they form in wet mud. The tutorial also covers mold and model fossils, explaining how they are created when organisms are buried in sediment. Examples include a fish mold fossil and a brachiopod model fossil.

What type of fossil is created by the mark of a living being?

• A mold fossil

• An impression or imprint fossil

• A mineralized fossil

How are dinosaur footprints typically formed?

• By a dinosaur resting on sand

• By a dinosaur walking through wet mud

• By volcanic activity

• By a dinosaur swimming in water

What remains in the sediment after a buried organism wears away?

• A mineral deposit

• A complete skeleton

• A hollow area shaped like the organism

• A solid rock

What is a mold fossil?

• A fossilized plant

• A hollow area shaped like an organism

• A fossil filled with minerals

How is a model fossil formed?

• By the organism being preserved in ice
