twizz: How does radiometric dating help scientists pinpoint the age of a fossil?
In radiometric dating, scientists use the rate of decay of radioactive materials in rocks to estimate the absolute age of a rock. That tells them the age of fossils found in that rock.
Radiometric dating allows scientists to find fossils in only the lowest and oldest layers of sediment.
In radiometric dating, scientists place samples of a fossil in certain liquids until the samples dissolve. The rate at which they dissolve indicates the age of the fossil.
In radiometric dating, scientists mix the carbon in a fossil with carbon from similar fossils whose age they know. By comparing, the carbon they can tell the exact age of the fossil.

because u is wack
you answered your own question! Other than the Zircon Crystals that contain Radioactive isotopes. These can be found in Biotite! A common mineral in many igneous and plutonic rocks as well as in sediment! these help determine the age but do not forget that your dating the age the crystal was formed in the mantle rather than the date of the sediment! Carbon dating only works in Short term! along with tree ring dating!Answer by KTDykes

Not quite. It can tell them the age of the rock, and that’s probably the age of the fossil. An exception is carbon-14 dating which, in the right circumstances, can tell you the age of the bit of animal or plant.

That doesn’t apply for most methods of radiometric dating.

No. They don’t do that, as that would be contamination of the sample, and it would make the result meaningless. Besides, most radiometric dating methods don’t involve carbon
