U-235 decays to Pb-207 with a half-life of 704 million years.

FAQ - Radioactive Age-Dating Planetary Science Institute

Due to its long half-life, U-235 is the best isotope for radioactive dating, particularly of older fossils and rocks. The half-life of C-14, however, is only 5,730 years.

C-14 is another radioactive isotope that decays to C-12. Because of its short half-life, the number of C-14 isotopes in a sample is neglible after about 50,000 years, making it impossible to use for dating older samples. in Earth-Space Science from West Chester University of Pennsylvania.
