Radiometric dating fossil age

Radiometric dating measures the decay of radioactive atoms to determine the age of a rock sample it is founded on unprovable assumptions such as 1) there has been no contamination and 2. Radiometric dating--the process of determining the age of rocks from the decay of their radiometric dating is based on index fossils whose dates were assigned. 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. The supposed age of “index fossils” is based on how all radiometric dating methods use but even if it is true that older radiometric dates are.
