    Zircon, for example, tends to crystallize with much less lead than uranium, and is thus useful for finding U-Pb dates.The observed proportions of parent and daughter give the date: But that cannot be universally assumed, and there is a way to get around the initial presence of daughter element.This scientific method for determining ages of specimens is also called radiocarbon dating, abbreviated RC. An Allosaurus excavated in Colorado was 14C dated 31,360 years before present ( /- 100 years). It is important to understand the simple, fundamental principle behind all dating methods, and why they are not able to produce objective, absolute dates (see article How dating methods work).The fatal flaw is that all scientific measurements are made in the present, whereas a date relates to a time in the past.

    James Joly calculated that the Earth’s age was 89 million years on the basis of the time required for salt to accumulate in the oceans.

    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.
