Lesson 9-Fossils

A fossil that is used to identify rock layers because the species lived all over but only lived a small amount of time. (Helps us know the boundaries of geological time)

• Index Fossil

• Trace Fossil

• Cast Fossil

• Fossil Resin

A type of fossilization that occurs when a sticky substance from plants preserves an organism.

• Permineralization

• Cabronization

• Mold

• Fossil Resin

The type of fossilization when an entire animal is preserved.

• Carbonization

• Permineralization

• Cast

• Ice/Freezing

The type of rock dating that gives a precise (exact) age.

• Differential dating

• absolute dating

• relative dating

Which of the following is true about fossils and rocks found in the same layer.

• The fossil is older than the rock

• The rock is older than the fossil

• They are about the same age.

What are 3 requirements for an organism to become a fossil?

(a)  

• Quick Burial

• Layers of Sediments build up over the organism

• Left for a long period of time

• Animal needs to die of a disease

• Ocean water covers organism.

How are marine fossils found on the tops of mountains?

• Organism died in water and fossilized. Then continental plates collided causing uplift.

• Rivers carry fossils up to mountain tips.

• Animals pick up fossils to chew on the bones and carry them up mountains.

What is the Theory of Continental Drift?

• The world used to be lava

• Tsunamis pushed the continents apart

• Animals crossed land bridges to find new habitat

• The continents used to be on single continent and drifted apart due to plate tectonics.
