Our attractive Diplomystus Dentatus fish frame measuring 695mm, an ancestor of the herring family, a very finely boned fish which is extremely difficult to prepare from the Lagerstätte varve layer of the Eocene limestones of the Green River formation 18-inch layer. These predator fish of an ancient freshwater lagoon have been discovered with other prey fish in its stomach contents, Knightia Alta, Knightia Eocaena and Priscacara Serrata all other inhabitants of the prehistoric fossil lakes and have occasionally found to the latter fishes stuck in its gullet. These so-called aspiration deaths are rare, difficult to interrupt as to the actual cause of the death of the predatory fish. The two main theories as to why aspiration fish deaths are found in the fossil deposits are, firstly the predator fish could not swallow the prey which became lodged in its throat and suffocated the attacker. Alternatively that the deoxygenation of the lake suffocated...

Our attractive Diplomystus Dentatus fish frame measuring 735mm, an ancestor of the herring family, a very finely boned fish which is extremely difficult to prepare from the Lagerstätte varve layer of the Eocene limestones of the Green River formation 18-inch layer. The lower Eocene deposits of Green River formation was thought to be a large freshwater lake or lagoon which suffered from occasional falls of volcanic ash which smothered the lagoon and helped to create an anoxic environment. This reduction of oxygen suffocated the inhabitants of the lake and in the process, preserved such specimens exceedingly well. This presented the perfect preservation process for flora and fauna alike, deposited within the silts at the bottom of the lake which eventually transformed into soft calcite bearing shale, eventually absorbed into these flora and fauna specimens, transforming these into the pieces they are today. The eighteen-inch layer is a lower Eocene varve layer, is not fissile laminae and...

Highly important and scientifically rare bony fish skull measuring 310mm, displaying distinctive mandibles and fully articulated skeletal maxillary with elongate and ferocious fossil teeth between the well-defined maxilla (upper) and mandible (lower) predatory jaws presented on a classic museum standard bronzed plinth and cradled upstand. the fossil jaw unearthed in a region of Morocco as a by-product of phosphate mining in the region of Casablanca, part of Africa which in prehistory belonged to Gondwana and associated with modern-day South America.The fossil fish 310mm is one of the bony ray-finned fishes of the Eocene period of Morocco, at least that is where this particular fossil was discovered. Morocco, situated in modern-day North Africa was once part of Gondwana and later Pangea before they broke up and formed the west, east Gondwana and Laurasia and fossils of the period may be discovered in North Africa and South America. It is also not unusual...

A rare side-necked Bothremydidae turtle skull and carapace shell display great preservation. Prehistoric Bothremys turtles are distinguishable for having two holes through the nose. This visually intriguing fossil turtle skull and carapace shell has undergone preparation, special seal treatment and secured within using our methods to better strengthen and preserve this specimen for display. The Palaeocene, a geologic epoch that lasted 66,000,000 to 56,000,000 years, was the first epoch of the Paleogene, the modern Cenozoic Era.You can find out more about fossil turtles here > Genus: Bothremydidae, Bothremys Maghrebiana.

Unveiling our special edition, the aquarium fish mosaic wall featuring warm calcified-limestone tiles which will present a unique dynamic to any abode, each prehistoric fish tile derives from a high-level fossiliferous rock layer, discovered off-piste in the Rocky Mountains of Wyoming. Each tile is hand-selected, expertly prepared using specialist micro-abrasive machinery, accenting each tile appropriately prior to the final cut or mitre, allowing us to acquire a natural display of shoals. Each specimen presents an original articulation and anatomical position, once the silt of a tropical lagoon some 50,000,000 years ago. 'Liken to an Athenian temple wall, combined with a prehistoric Lascaux cave - the composition of the aquatic scene creates a sense of tranquillity and seamless transition throughout the warm soft-toned limestone mosaic fish wall’.

An extremely rare Lebanese multi-plate displaying two very large and well preserved prehistoric Ray and Shovelnose shark on a single and original sub-lithographic limestone slab.Ray and Shovel Nose Shark wall statement from Lebanon. With a custom wall hanging system included, this beautifully preserved in natural lithographic limestone dating back to the Mesozoic era, upper Cretaceous period, Cenomanian stage, around 99,000,000 to 93,000,000 million years. Both specimens are attractively articulated showcasing fine details of their anatomies. In the top right you can see the Rhinobatos Hakelensis, commonly known as the 'Ray fish'. And in the bottom left; Libanopristis Hiram commonly referred to as the 'Shovelnose shark'. Both originating from the sub-lithographic limestone formation in Haqel, Lebanon. Now presented after being patiently restored for interiors.
