can uranium 235 use for dating dinosaur bones

Whitmore, et al. Anything that is older than about 60, years cannot be dated with carbon, though there are other dating methods like electron spin resonance, thermoluminescence, and optically-stimulated luminescence or other isotopes with longer half-lives like potassium or uranium that may be useful for older materials like dinosaur bones and minerals. This scheme is used to date old igneous and metamorphic rocks , and has also been used to date lunar samples. But for some people, the discovery raised a different question. Carbon is a radioactive isotope of carbon, with a half-life of 5, years [28] [29] which is very short compared with the above isotopes , and decays into nitrogen. August 4, 5 min read.
