Other corrections must be made to account for the proportion of throughout the biosphere (reservoir effects).

Additional complications come from the burning of fossil fuels such as coal and oil, and from the above-ground nuclear tests done in the 1950s and 1960s.

In 1898, Marie Curie discovered the phenomenon of radioactivity, in which unstable atoms lose energy, or decay, by emitting radiation in the form of particles or electromagnetic waves.

By 1904 physicist Ernest Rutherford showed how this decay process could act as a clock for dating old rocks.

The Museum, which has since 2005 been in cooperation with the Paleochronology Group, a team of consultants in geology, paleontology, chemistry, engineering, and education, sent a sample of the outer portion of the Triceratops brow horn to Head of the Paleochronology Group Hugh Miller, at his request, in order to carry out Carbon-14 dating.However, scientists from the Paleochronology Group, who perform research relating to “anomalies of science”, maintain that dinosaurs did not die out millions of years ago and that there is substantial evidence that they were still alive as recently as 23,000 years ago.Until recently, Carbon-14 dating was never used to test dinosaur bones, as the analysis is only reliable up to 55,000 years.Scientists now have accurate methods (see below ) for dating fossils.methods rely on characteristic faunal and geological patterns to bracket the period when the fossil existed.
