The bird lived for a very short time. The bird lived in a dry environment. The bird existed at one time but is now extinct. The bird was not well preserved during the process of fossilization.
I gave my students this multiple choice question: A complete fossil has been found of a type of bird that cannot be identified. What can most likely be determined about the bird from the fossil?

Only one answer is correct among these 4 choices:
- The bird lived for a very short time.
- The bird lived in a dry environment.
- The bird existed at one time but is now extinct.
- The bird was not well preserved during the process of fossilization.

Could you tell me which one is correct?

The bird existed at one time but is now extinct.
