Radiocarbon dating flaws

Other useful radioisotopes for radioactive dating include Uranium -235 (half-life = 704 million years), Uranium -238 (half-life = 4.5 billion years), Thorium-232 (half-life = 14 billion years) and Rubidium-87 (half-life = 49 billion years).

The use of various radioisotopes allows the dating of biological and geological samples with a high degree of accuracy.

Researchers have found a reason for the puzzling survival of soft tissue and collagen in dinosaur bones - the bones are younger than anyone ever guessed.

That included protecting the samples, avoiding cracked areas in the bones, and meticulous pre-cleaning of the samples with chemicals to remove possible contaminants.

This is how carbon dating works: Carbon is a naturally abundant element found in the atmosphere, in the earth, in the oceans, and in every living creature.

C-12 is by far the most common isotope, while only about one in a trillion carbon atoms is C-14.

The Triceratops brow horn was excavated in May 2012 and stored at the Glendive Dinosaur and Fossil Museum.

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.

Plants and animals naturally incorporate both the abundant C-12 isotope and the much rarer radiocarbon isotope into their tissues in about the same proportions as the two occur in the atmosphere during their lifetimes.
