Larg Ammonite Fossil Fire Red Iridescent Cretaceous on Matrix 36 x 28 cm + Stand
Large Ammonite Fossil Fire Red Iridescent Cretaceous on Matrix Display 36 x 28 cm + Stand Large Whole fire red Cleoniceras ammonite fossil mounted on Matrix.The beautiful flashes of reds and greens are produced by the mineral aragonite , which has replaced the original shell. This particular ammonite has exceptionally attractive flashes of green and reds when turned to the light.P olished and smooth, with a spiral pattern which reflects the wonder of nature. The ammonite is entirely natural but has been mounted matrix which would have been from the surrounding rock bed but the fossil would have been found near it and mounted to make a beautiful display piece. Supplied with a giant acrylic click and twist display stand.
Date: Cretaceous 120 to 110 Million years Old
Provenance: Jungles of Mahajanga, North East coast Madagascar
Size: Size of Matrix 36 x 28 cm Size of ammonite itself is 10.8 x 8.7 cm. Weight 3 kg
Condition: The reds and greens can be best seen when tilted towards the light .code 1198
What is a Fossil? 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.
