Petrified Wood is a type of a fossil as it consists of fossil wood where all the organic materials have been replaced with minerals while retaining the original structure of the wood.  These minerals are most often Silicates such as Quartz.  Other minerals, Manganese, Iron and Copper, in the water or mud during the petrification process give Petrified Wood a variety of color ranges: black - Carbon; green/blue - Copper; red/brown/yellow - Iron.  Petrified Wood can preserve the original structure of the wood in all its detail all the way down to the microscopic level.  Structures such as tree rings and the various tissues are often observed features.  Although Petrified Wood can be found worldwide, it is rather rare in larger quantities and at times can be difficult to obtain by the average collector.

This set weighs 12 lbs. 12 ozs.

Orthoceras Bookends

BK506b   Here is a very nice, above average quality set of Black Orthoceras bookends.  This set measures 8" x 6 1/2" x 2" and has a nice polish on the front, middle, top and side faces.  The bookends have been cut, carved and polished from Fossil Rock material to expose the very unique fossils and have an unique dotted pattern on the front face.  This material is from Morocco.  The bookends make great decorator pieces as well as super collectibles for the fossil hunter.

Orthoceras is a genus of extinct Nautiloid Cephalopod.  These fossils are common and have a global distribution which occur in any marine rock, especially Limestone.  These are slender, elongated shells with the middle of the body chamber transversely constricted and a sub-central orthochoanitic siphuncle.  The surface is ornamented by a network of fine lirae or fine lines/ridges.

They weigh 8 lbs. 9 ozs.

The set weighs 7 lbs. 15 ozs.
