Description: Kates Collections Whole Iridescent Opalescent Fossil Ammonite with Hand Crafted Steel Display Stand Whole ammonite fossil; exceptional iridescence which is entirely natural . These natural and beautiful rainbow flashes of colour , when turned towards the light,are produced by the shell of the fossil being replaced by the mineral aragonite , many millions of years ago. Supplied with a locally hand crafted steel display stand painted black. Lovely and unusual gift ,display piece or addition to a collection. The ammonite comes with ID card pictured , making it an ideal gift.I do not enhance the pictures but they can appear brighter and with more intense colours in the pictures .

Size: 14.3 x 11.7 cm depth 3. 8cm weight 636 gm Condition: The ammonite has some good detail and preservation and beautiful rainbow flashes. As it is an entirely natural product and is also as millions of years old, there may be natural flaws. Some of the pictures may appear larger, due to the angle of photography.

Fossils give fascinating prehistorical evidence of past life on our planet. Usually, fossilization starts once the animal or plant has died. Most animals and plants are eaten or simply recycled back into the earth. The best fossils occur when this process happens rapidly, shortly after death has occurred. Conditions have to be exactly right for a fossil to be produced. Most commonly, this is below water. Decay and deterioration are slowed down because the specimen is covered or entombed in either sediment, muds, sands or volcanic ash or other material, layer upon layer, and over a period that is hard to imagine, usually thousands to millions of years. Preservation takes place very gradually, as it compacts, it slowly turns to rock. Over time, the plant or animal is replaced by minerals and with chemical changes, leaving an extraordinary replica of the original. In some cases, the pressure and temperature increase, caused by sedimentation, can result in the release of hydrogen and oxygen, leaving a carbon impression of the specimen in sedimentary rock. This process is called carbonization. Fossils can become preserved in various different ways. For example, wood can become petrified by a process of minerals seeping into the saturated wood, resulting in a gradual process of the wood becoming hard, and resembling stone, often with extraordinary colours. In perimineralization or petrification, after the soft structures have decayed, the hard parts, in particular bones, remain. In some cases, the other minerals completely replace the original specimen. Generally, most fossils represent the hard parts such as bones, shells, leaves, seeds or woody parts of plants. Fossils can be internal or external moulds of the original specimen. They can also be the some of the original matter, impregnated with chemicals such as silica or calcite. Fossils can also be indirect, such as in animal foot prints or burrows. These are known as trace fossils.
