Carbon dating lava not
The fossil shrimp and fish in this layer of sedimentary rock from Lebanon date back to the Middle Cretaceous era, about 95 million years ago.

In other words there was originally 4 parts per million Parentium-123 and 0 parts per million Daughterium-123.
Martha Foley and Curt Stager discuss the problems of reading the geological clock.James Hutton, a physician-farmer and one of the founders of the science of geology, wrote in 1788, “The result, therefore, of our present inquiry is, that we find no vestige of a beginning, — no prospect of an end.” Although this may now sound like an overstatement, it nicely expresses the tremendous intellectual leap required when geologic time was finally and forever severed from the artificial limits imposed by the length of the human lifetime.By the mid- to late 1800s, geologists, physicists, and chemists were searching for ways to quantify the age of the Earth.Imagine we have an undiscovered element, Parentium, that has a radioactive isotope, Parentium-123, which decays to stable Daughterium-123.This is the only way Parentium-123 decays, and there is no other source of Daughterium-123.
