Radioactive dating of fossils Iranin free video sex chat
The half-lives of several radioactive isotopes are known and are used often to figure out the age of newly found fossils.
Different isotopes have different half-lives and sometimes more than one present isotope can be used to get an even more specific age of a fossil.
If the accepted ages of millions of years for dinosaurs were to be found to be in error, this would be a problem to evolution.
The dinosaur dates reported below and discussed in the AOGS 2012 paper discussed throughout this article, included triceratops, hadrosaur, allosaurus, and acrocanthasaurs.
There are several reasons why, but the main reasons is that Carbon-14 is a naturally occurring isotope in all forms of life and its half-life is about 5730 years, so we are able to use it to date more "recent" forms of life relative to the Geologic Time Scale.
In other words, half (50%) of the Carbon-14 you started with has decayed into the daughter isotope Nitrogen-14.
However, your readout from your radioactivity measuring instrument says you have only 25% Carbon-14 and 75% Nitrogen-14, so your fossil must have been through more than one half-life.
The age for all these fossils was found to be less than 50,000 years1.
This is not predicted by conventional evolutionary theory; and other discoveries have been made concerning dinosaurs which also are not predicted by evolutionary theory such as the discovery of soft tissue in bones that are not or are only partially fossilized.
