Jeletzkytes spedeni Ammonite

Handmade brass display with three Opalized Ammonites from Madagascar fields, Albian Period (100–140 million years old). When opalized can be also called as Ammolite is an opal-like organic gemstone found in various placed in the North America and Madagascar. Ammolite is made of the fossilized shells of ammonites, which in turn are composed primarily of aragonite. The microstructure of the mineral is inherited from the shell.

It is one of few biogenic gemstones. Other more commonly known biogenic gemstones include amber and pearl. Ammolite was officially recognised as gemstone species in 1981. Ammolite “opalization” is a term used to express the similarity between the two minerals due to the spectrum of colours it displays. Usually red and green, whilst, blue or purple are rare due to the latter's fragility.

A unique One of a Kind signature piece.

Polished Orthoceras slab fossil with over 400 million years.

As these forms of prehistoric squid were covered in ocean sediments prior to fossilization, the majority of the creatures will be facing in the same relative position, having been lined up by currents on the sea floor prior to being buried. The fossils are exposed and given a high polish to better view the creatures from their surrounding matrix.

The slab features very high relief as well as dramatic texture and detail they had tentacles and ink sacs, much like present-day squid. Except for belemnites, cephalopods had external shells with hollow internal chambers separated by walls called septa. Devonian period, circa 410 million years, Anti-Atlas Mountains - Southern Morocco - mounted in a black granite base.

It comes from the Tsingy de Bemaraha National Park in Madagascar.

Great pattern and colours. A one of a kind piece. 

Orthoceras column fossil, a captivating relic hailing from a time more than 400 million years ago. These prehistoric squid-like beings, preserved through eons within oceanic sediments, offer an unparalleled glimpse into the past. Elegantly aligned by primordial currents on the ocean floor prior to their entombment, these creatures maintain their relative positions, frozen in the embrace of time.

Skillfully revealed through meticulous exposure and a masterful polish, the fossils come to life against their matrix backdrop. The artful interplay of light and shadow accentuates the delicate features of these long-extinct cephalopods. With their tentacles and ink sacs, reminiscent of their modern-day squid counterparts, these creatures possessed a mystique that transcends eras. Notably, these cephalopods boasted external shells, characterized by hollow internal chambers partitioned by intricate walls known as septa, a fascinating trait shared by their kin.

Originating from the Devonian period approximately 410 million years in the past, this fossil bears witness to the eons that have passed, finding its origin amidst the rugged landscapes of the Anti-Atlas Mountains in Southern Morocco.

Cretolamna Aschersoni in matrix, in acrylic base.

Beautiful Lamna Aschersoni shark teeth in their natural matrix, from Cretaceous era (66.0–145.0 million years) - Oued Zem – Morocco.

Carcharodon Megalodon (Megalodon meaning “Big Tooth”) is an extinct species of shark regarded as one of the largest and most powerful predators in vertebrate history.

This beast lived approximately 23 to 3.6 million years ago, during the Cenozoic Era. Fossil remains suggest that this giant shark reached a length of 18 metres (59 ft), from USA.

Displayed in a glass box made to measure. 

This magnificent pair of table trays is crafted from twin slices of Araucaria petrified wood, dating back to the Triassic period—an astonishing 220 million years ago. Originating from the Ambilobe region in Northern Madagascar, these slices showcase dramatic patterns and rich, natural colors that highlight their ancient origins.

To elevate their elegance and functionality, each slice has been expertly mounted with nickel-plated brass hardware, transforming them into a perfectly matched pair of unique table trays. Rare and truly one-of-a-kind, these trays are not only a testament to Earth's history but also a stunning addition to any home or collection.

Madagascar Copal Amber with leaves and insects, mounted in a handmade dark brass base.

Amber is a substance derived from resins (Fossil Resin) of trees and plants that, buried for millions of years, underwent into a fossilization process.

These resins produced by plants acted as protection against the action of bacteria and against the attack of insects that punctured the bark until reaching the interior of the trees.

Over millions of years, amber-forming organic substances ended up forming a hardened, weather-resistant resin.
