Natural Gogotte Formation
Located in London, GB
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...

Large Chondrite Meteorite with Regmaglypts
Located in London, GB
NWA 12759
Stone, Chondrite - L5
18.3 KG
“This specimen of the NWA 12759 L5 chondrite has a smooth posterior fusion crust where meteoritic melt pooled as the rock descended through the atmosphere and was heated by friction with molecules of air. The meteorite is from the L-chondrite asteroid that was destroyed by an energetic collision 470 million years ago.”
Dr Alan E. Rubin, PhD Department of Earth, Planetary, and Space Sciences, UCLA
Detached from its parent body by a mighty impact, this large, oriented meteorite travelled over a hundred million miles through space before falling to Earth in the North African desert. Beautiful regmaglypts radiate from the apex of its cone shaped nose. These elongated dimples formed when streaks of superheated molten rock streamed off the meteor’s surface as it blazed through the atmosphere. The entire piece is coated in a glossy, umber-coloured fusion crust and close examination reveals remnants of encrusted, orange dirt.
Whilst most meteors tumble as they travel through the Earth’s atmosphere, oriented meteorites...

Monolithic Stone Meteorite
Located in London, GB
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.”

Oriented Chondrite Meteorite Circa 4.56 Billion y/o
Chondrite
24 x 20 cm, 28 cm tall on base
7.1 kg
A sculptural and beautifully weathered chondrite meteorite; upon entering the atmosphere, this extraterrestrial stone would have heated the surrounding air to a temperature of over 1700 C, higher than that of the hottest lava on the planet, and enough to melt away its outer layers, leaving its surface rippled with regmaglypts, thumb-shaped impressions formed as superheated rock streaked off of the main body as it careened toward the earth. The last layer of the rock to melt would have re-solidified as the meteorite made impact, forming a charcoal coloured fusion crust, which has taken on a deep ochre-tinted patina.
Chondrite meteorites such as this example were formed at the very beginning of our solar system, by the accretion of various types of dust and small grains, adrift in the vacuum of space and, as such, provide important clues about the birth of our own planet. This piece is an especially rare specimen, known as an oriented meteorite...

Earthly Treasures No 27, an Elm & Cornish Turquoise Sculpture by Morrison Thomas
By Morrison Thomas
Located in London, GB
‘Earthly Treasures No 27’ is a unique sculptural bowl by the British artist, Morrison Thomas. It is made from burred English Elm inlaid with Cornish Turquoise.
Morrison turns beautiful wooden spheres from damaged or diseased trees that have been felled as they can no longer survive. Using aged wood such as this, reveals cracks and crevices which the artist can inlay with precious minerals. The results are breathtaking. These take on the role of globes and are evocative of old maps. The minerals suggest undiscovered islands and continents.
During Thomas’ time as a designer and maker of furniture it was usual practice to mask and hide any blemishes or cracks in the wood, however much like the Japanese art of Kintsugi (where ceramic breakages are repaired with gold and precious metals) Thomas highlights the anomalies in the wood by inlaying them with naturally formed colorful minerals, many taken from his personal collection which he still adds to. Recent visits to the ‘World Famous’ Blue John Mine and also a working Fluorspar mine in Derbyshire has meant new materials for future inlays. With the wood hard to find and unpredictable to turn, the resulting union of the Earth’s natural resources are patiently and skilfully jigsawed together, resulting in truly unique treasure-laden artworks.
Is his own words:
‘The two mediums I combine both come directly from the Earth. The trees form and grow at the surface whilst the minerals can form at great depth. It is not unknown for some trees to have accumulated pieces of crystals in their roots. The thought of this combination of a substance formed during explosive episodes in the Earth millions of years ago with a gently formed living substance, which may have been growing for hundreds of years before finally coming to an end, is both exhilarating and intriguing. I think of it as a fusion between animate and inanimate, above and below the ground, naturally both beautiful, and without which, we as humans could not survive’
Morrison Thomas was born at New Inn Cottage in the tiny village of Charlton near Banbury, Oxfordshire. His father was a cabinet maker & carpenter who was also a wheelwright and blacksmith, as with many village craftsman of the time, he was skilled in all things. Keeping the family tradition, Thomas continued in his father’s footsteps and is a fourth generation woodworker.
As a furniture designer & maker Thomas has exhibited his work in numerous high profile galleries and undertaken many prestigious commissions. He has written articles on woodworking with his work appearing in numerous publications. Previously the chairman of the Surrey Guild of Craftsmen and with a listing in Debrett’s Who’s Who, his achievements are many, especially in consideration that he received no formal training, with his skills obtained from observing and listening to his father.
For many years Thomas designed and made contemporary furniture but mainly due to health reasons stopped making larger-scale works. With woodworking in his blood and a material he simply couldn’t stop creating with, he resumed his creative skills some years later by making unique hand-turned wooden vessels...

Edmontosaurus Skull
Located in London, GB
An impressive skull of an Edmontosaurus, a large herbivorous dinosaur that lived during the Late Cretaceous period, 68-66 million years ago. The three rows of sixty or more teeth on either side of the jaw, known as the ‘dental battery’, mark the Edmontosaurus as part of the Hadrosauridae, or duckbill family of dinosaurs. It belongs to the flat-skulled, or solid-crested, Hadrosaurinae, which replaced the older hollow-crested hadrosaurs. Edmontosaurus was one of the last non-avian dinosaurs to ever exist, living shortly before the Cretaceous-Paleogene extinction event.
The Edmontosaurus was named in 1917 by Lawrence Lambe, after a partial specimen from Edmonton in Alberta, Canada. The existence of large Edmontosaur bone beds...
