A paleontologist has discovered a fossil of a jawbone from a prehistoric carnivore. It is similar to the other fossils found in nearby areas but has some unique characteristics and was found in a much deeper rock layer. Which of the following is a reasonable conclusion about the fossilized animal?

• It is the same age as the other fossils found in nearby areas.

• It is older than the other fossils found in nearby areas.

• It is a different species than the other fossils found in nearby areas.

The animal was an ancestor of the other fossils.

• The animal was the same species as the other fossils but lived much more recently.

• The animal was a descendent of the other fossils but became extinct due to poor adaptations to the environment.

• The animal was an ancestor of the other fossils.

• The animal was an unrelated carnivore that lived in the area long before the other fossils.
