2.1 Uranium-lead dating method
2.2 Samarium-neodymium dating method
2.3 Potassium-argon dating method
2.4 Rubidium-strontium dating method
2.5 Uranium-thorium dating method
2.6 Radiocarbon dating method
2.7 Fission track dating method
2.8 Chlorine-36 dating method
2.9 Luminescence dating methods
Just to name a few independent radiometric dating sources, all of which have a margin of error under 5% and all overlap which is how we estimate dates. Carbon actually isn't really used much for dating fossils.
