The word "Fossil" is from ancient Latin, meaning "having been dug up". This however would be considered an extremely loose translation. In regard to organic material that has gone through a natural cellular replacement process, many insist that technically a fossil must be at least 10,000 years old. However other "fossilized" specimens which have not yet turned completely into stone but are partially fossilized are still considered to be fossils by many. Regardless, a fossil, no matter how well preserved is a very rare occurrence, as the conditions for its creation must be just right for its permineralization / replacement process to occur. A specimen upon its demise must be immediately buried in order to prevent rapid decomposition. Also, the specimen must be close to a mineral rich water source which over time slowly allows the organic cellular structure of the specimen to be replaced with minerals, molecule by molecule.
Here you can peruse fossil specimens from many different Geological time periods. We hand select and guarantee all of our specimens. Please contact us for any questions you might have, or simply give us a call at (847) 866-7374.
