What are fossils?

• The preserved remains of animals, plants, and other organisms from the distant past.

• Rocks and minerals found on Earth's surface.

• Artificially created models of organisms.

• Modern animals and plants.

What is the fossil record?

• Are the remains or evidence of once-living organisms

• Is the change over time in populations of related organisms

• Is made up of all the fossils ever discovered on Earth

• Occurs when the last individual organism of a species dies

What is a mold?

• The impression of an organism

• Is the preserved evidence of the activity of an organism

• A fossil copy of an organism in a rock

• A chart that divides Earth’s history into different time units

What is a cast?

• The impression of an organism

• Occurs when the last individual organism of a species dies

• Is made up of all the fossils ever discovered on Earth

• A fossil copy of an organism in a rock

What are trace fossils?

What is extinction?

What is the geologic time scale?

• A chart that divides Earth’s history into different time units

What are the different types of fossils?

• mold fossils, cast fossils, trace fossils, true form fossils, petrified fossils

• fossilized fossils

• mineralized fossils

• imprint fossils

The similarities of the bones in the diagram provide evidence that---

• The organisms shown lived in the same natural envionrment
• The organisms shown may have developed from a common ancestor
• The organisms shown have the same genetic diseases
• All vertebrate species have identical forelimbs

Because whales have a pelvis and femurs, it shows whales are descended from an ancestor that was able to _____________________.
