Final answer:

Uranium-238 is the best radioactive isotope for determining the age of the ancient skeleton due to its long half-life of 4.5 billion years.

Explanation:

Uranium-238 would be most useful for finding the age of the 10,000 to 25,000-year-old skeleton. Uranium-238 has a half-life of 4.5 billion years, making it suitable for dating ancient objects older than 50,000 years when carbon-14 dating is not effective.
