A geologist would date a **woolly mammoth fossil that existed 15,000 years ago** using carbon-14 dating. Carbon-14 dating is effective for dating organic materials that are up to about 50,000 years old, making the woolly mammoth fossil a suitable candidate. The other options involve materials that are either much older than what carbon-14 dating can effectively date or are inorganic.
