Kelli drew a diagram to compare cast and imprint fossils.

• Involves minerals replacing remains of organism

• Takes millions of years to form

• Gives evidence of organism's activity

• Involves mold filling with minerals and sediment

Which statement best compares a trace fossil to a fossil that forms as a result of an entire organism being trapped in amber?

• Both show the exact structure of the organism.

• Both require that the hard parts of the organism dissolve.

• Both form as a result of the organism leaving imprints in sediment.

• Both can possibly be used to study the organism's size.

A scientist has a fossil that was found in a layer of rock close to Earth’s surface. He believes that the fossil is around 12,000 years old.

• finding another fossil in a deeper layer of rock

• finding another fossil in the same layer of rock

• using carbon/nitrogen absolute dating

• using potassium/argon absolute dating

A scientist observes fossil evidence that leads her to believe that certain organisms have a common ancestor.

Which observation most likely led to this conclusion?

• She observed older fossils that contained many of the same minerals as the newer ones.

• She found skeletons of modern organisms in the same area as fossilized organisms.

• She observed a fossil with skeletal structures similar to certain modern organisms.

• She found several fossils in rock layers directly below other fossils of similar size.
