Fossil dating techniques

The range of conventional radiocarbon dating is 30,000 to 40,000 years.

With sensitive instrumentation, this range can be extended to 70,000 years.

Absolute dating methods are carried out in a laboratory.

If you want the rundown on how we learned to do this, I recommend Simon Winchester's highly readable nonfiction book The Map that Changed the Worldwhich is about the birth of stratigraphy as a field of study and how we came to know that our Earth is billions of years old.

Radioactive decay refers to the process in which a radioactive form of an element is converted into a nonradioactive product at a regular rate.The nucleus of every radioactive element (such as radium and uranium) spontaneously disintegrates over time, transforming itself into the nucleus of an atom of a different element.

  2. She says she is 39 years old, but that supposedly was in 1999. After that I was swamped with letters but only from one agency... I'm having a similar experience as a few of the other gentlemen with and through E700

  3. And indeed, as people tuned in to their headphones they tuned out all else around them, including other humans. We type at each other on Facebook and Twitter, look at the pictures and watch the videos.
