Fossilised Dinosaur Skin

A magnificent example of a gogotte formation 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 aesthetic concretions we now know as gogottes. These are rare and are only found sporadically several metres deep into the ground. 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 intriguing name of “gogotte” was coined by French geologist Claude Guillemin (1923- 1994), who was inspired by the children’s book series Babar the Elephant. In one of the books, a group of monsters called Gogottes are shown hiding behind rocks. These rocks reminded Guillemin of the sandstone concretions...

Unclassified Meteorite Stone Height: 36.83 cm 42.5 kg A dramatic extraterrestrial sculpture, of monolithic form, covered in a thick grey-brown fusion crust and with areas of sandy deposits from untold years spent on the desert floor. Formed in the asteroid belt between Mars and Jupiter during the formation of our solar system, some 4.55 billion years ago, this large stone would have been separated from its parent body by an enormous impact before journeying through interplanetary space and eventually reaching Earth. Upon atmospheric entry it would have reached cosmic velocity, heating the surrounding air to 1700°C and producing a large ball of fire. The heat was sufficient to melt the outer surface of the stone, exposing a new surface which in turn also melted away, losing as much as 95% of its initial mass before reaching the ground. The last molten layer to form as it collided with the Earth covered the stone in a layer of fusion crust, evidence of the incredible impact force delivered by this extraordinary specimen. “This unclassified stone meteorite was found in Northwest Africa. It has a relatively smooth, dark brown, slightly weathered fusion crust; some small melt veins are visible on the surface. Due to the near-absence of terrestrial rocks in this region of the Sahara, meteorite hunting in this area has yielded many notable discoveries.” Dr Alan E. Rubin, PhD Department of Earth, Planetary, and Space Sciences...
