Iridescent Ammonite Fossil

About the Item

Large spectacular iridescent ammonite fossil. 75 Million y/o A magnificent example of one of the most spectacular fossils. A large and intensely vibrant ammonite, Placenticeras costatum, from the Bearpaw formation, Alberta, Canada, dating to the late Cretaceous period, around 75 million years before present. The surface of this long extinct marine creature has transformed over millennia into a dazzling, iridescent gemstone, its colours shifting in the light from vivid reds to emerald greens, to flickers of orange and gold, purples and brilliant blues. This effect is a natural result of the fossilisation process, a unique phenomenon only found on ammonites recovered from this location. The ammonite, an extinct branch of the mollusc family, related to the modern octopus, takes its name from an ancient belief, recorded by Pliny the Elder, that their fossilised remains were in fact the horns of the ram-horned Egyptian god Ammon, which would bring good fortune to the owner. Most fossils of this kind are heavily restored or pastiches, and their colour is often artificially enhanced with varnishes. This example is completely preserved, with its unrestored original surface - a superb piece of natural history. Most fossils of this kind are heavily restored or pastiches and their colour is artificially enhanced with varnishes. This is a completely preserved, natural piece with original surface. Mounted on a bespoke bronze base. Measures : Diameter: 42 cm. Height with stand: 47 cm Provenance: Discovered in the Blood Reserve, Alberta, Canada.

  • Natural Gogotte Formation
    Located in London, GB
    'Louis XIV' Gogotte Formation Measures: circa 30 Million y/o 105 x 76 x 15 cm A magnificent example of a gogotte formation, nicknamed Louis XIV, composed of thick swirls and folds of sparkling sandstone. Discovered in the Oligocene sand dunes of Fontainebleau, France, formed circa 30 million years before present or later. The incredible, almost otherworldly appearance of gogottes may easily be mistaken for the work of a most talented artist. In fact, these sandstone sculptures are entirely natural in origin. They have been found in multiple locations but those from Fontainebleau, such as the present example, are the most remarkable. Thirty-five million years ago, a sea covered what is now the forest of Fontainebleau, and dunes of exceptionally fine and homogenous sand formed. As silica-rich water filtered through this sand, it turned into stone. The flow of water finely modelled the sandstone into the forms we now know as gogottes. These are rare and are only found sporadically, several metres buried underground. They owe their sparkling white appearance to the extreme and unmatched purity of the Fontainebleau sand, sometimes reaching a composition of 99.9% silica. Each of them is unique – a masterpiece slowly fashioned by the hands of Nature. The name “gogotte” was coined by French geologist Claude Guillemin (1923- 1994), inspired by the children’s book series Babar the Elephant...
