The petrification of wood involves the replacement of the original tissue with a mineral. At the beginning of the process, minerals in solution fill up the small hollows of the wood, and then silica or calcium carbonate chemically replaces the tissue. The re-crystallization in silica, due to the pressure and to the increase of the temperature, together with the presence of impurities in solution, leads to the formation of new minerals like agate or, more rarely, opal. This process destroys the original structure of the wood.
The remains of many plants which lived about 250 million years ago during the Permian Age petrified, changing into silica through a process called permineralization. Silicized vegetal fossils are easier to find, while those, which still faithfully maintain the histological structure are less common. These specimens come from Brazil, where their richness of detail has remained unchanged through millions of years.
All fossils and minerals come packaged in an attractive box filled with kraft or wood excelsior and includes a descriptive card. This presentation makes a great display and a cool gift!
A note about fossil and mineral specimen photographs shown on this website.
Specimens priced over $50.00 - If priced over $50.00, the photo is of the actual specimen that you will receive.
Specimens priced $50.00 or less - The photographs of fossils and minerals on this website depict "typical" specimens if priced $50.00 or less. These are not manufactured products. Accordingly, product samples will vary significantly in size, shape, and color from the "typical" specimen in the photograph. If you would like to see a photo of the actual specimen that you will receive, please email us your request and we will try to comply with the request within a couple of days.
All of the fossil specimens offered by Nature's Odyssey are from the GeoWorld Group of Italy. Nature's Odyssey is the only company in the United States to offer these products which have become very popular at the GeoWorld Nature Stores found throughout Europe. The GeoWorld Group works all over the world studying, searching for, and extracting fossils and minerals. The fossil specimens are prepared in Italy, in GeoWorld's Laboratory, by a qualified group of experts, who restore and classify rare and unique pieces as well as common small specimens. Minerals, in turn, undergo delicate cleaning operations and, if necessary, conservative treatments.
