Geocoma libanotica fossil brittle stars which lived during the late Cretaceous period approximately 95 million years ago. The samples are preserved on a micritic limestone matrix called lagerstatten which has a fine grain texture and beige colouration. They come from the renowned Hajoula region in Lebanon and each brittle star measures approximately 30 mm in size while the overall matrix is square shaped measuring 10 x 10 cm making them suitable as little gifts, for enthusiasts, young collectors or educational use. Each piece will come supplied with a stand and small information label.

Geocoma libanotica are a species of brittle stars which lived during the late Cretaceous period approximately 95 million years ago in what is now Lebanon. These particular species have also been described from European localities but with specimens around 50 million years older. They are preserved on a beige coloured, fine grained micritic limestone known as lagerstatten, however, despite their delicate appearance, one can still clearly see the animals shape and arms and are complete. They come from the famous Hakel deposits, an are well known for exceptionally preserved fish and crustaceans in the world in a large abundance. It is believed that 95 million years ago, the areas was a warm coast line and home to a number of flora and fauna, however, an event (which still occurs to this day) known as ‘waterbloom’ occurred at the waters surface in which plankton developed in such a large quantity, which not only depleted oxygen within the area but also released toxic chemicals into the surroundings as well, causing a mass death of organism in a short period of time. These particular samples of brittle star fossils measure around 30 mm in size resting on a matrix cut into 10 x 10 cm squares. They come supplied with a stand and information label, suitable for enthusiasts, young collectors or educational use.

Fossil twigs, collected from Madagascar. These twigs are Triassic in age and come supplied in packs of 5 pieces. Packaged in a polythene bag with an information label.
Isastrea fossil coral of Jurassic age, collected from Steeple Ashton, Wiltshire, UK. Isastrea is an extinct species of Scleractinian coral which existed in the Jurassic and Cretaceous periods. These reef building corals had a symbiotic relationship with photosynthetic algae and so lived in in shallow, warm, clear marine waters. These specimens measure approximately 3″ in size and come in a white card tray with an information label.

Grammoceras is an extinct genus of Ammonite, which existed during the Jurassic period. Distinct due to their disc-like curved shell and distinct, thin ridges. These ammonite specimens are very well preserved, making them a perfect tool for analysis,while also providing the quality to become a display piece in fossil collections, particularly those geared towards UK marine fossils. These particular specimens are of an unknown species and were found in Illminster, Somerset, UK. They range from 1″ – 2″ and come provided with a white card tray and information label.

A colonial coral which lived in warm shallow waters and is common in the limestone rocks of the Silurian period. Favosites is often associated with other corals that formed small reefs. Favosites specimens have a honeycomb appearance when viewed from above. Specimens come in multiple sizes in a white card tray with an information label.
A specimen of a Hexagonaria, which is an extinct genus of rugose coral, found in the Sahara Region, Morocco. The specimens belong to an unknown species and have been polished. This makes them a great addition to any collection. Additionally, the rough genuine face beneath provides an excellent tool for analysis. All specimens are Devonian in age, approximately 2-3″ in size and supplied in a white card tray with an information label.
Ogyginus comdensis was a species of asaphid trilobites from the Ordovician period, and found in abundance in Wales. They were characterised by their squat, rounded bodies. These specimens are preserved within a mud stone matrix, some of which has been polished, but all of which has been cut to display the fossils in their entirety. A perfect specimen for analysis of different orders of trilobite if purchased along side a more common variation, these fossils could also be used as a display piece. All fossils are provided with a white card tray and information label.
Available in the folowing sizes:
These sizes refer to the length of the trilobite, not the matrix they are contained in. Matrix size varies between specimens.
Flexycalymene trilobite fossils, (syn: diacalymene) are a well known extinct species which lived during the Ordovician period, 449 to 443 million years ago and were found in Erfoud, Morocco. These samples exhibit quite clear morphological features such as the pygidium, cephalon and thorax as well as the shape and segments as expected. They appear to have a rusty, limonotic colouration which is due to iron oxide staining in the beds the fossils were found in. Available in various sizes and come supplied in a tray with a label.
Specimens of echinoid spines from Morocco, the species is unable to be identified from these spines alone, they are supplied in lots of 100 g and come in a polythene bag with an information label.
Perisphinctes are an extinct species of ammonite which lived during the lower Jurassic period, 163 to 145 million years ago. The animal could grown from anywhere between 10 mm to over a meter in diameter, making them among the largest of the ammonites. Their shells exhibit excellent morphological features such as clear, distinct ribbing and occasionally, well defined ammonitic suture lines, among the near perfect coil shape, it could be said that perisphinctes are the text book ammonite. These specimens are 1.5″ – 2″ in size and come supplied in a white card tray with information label.
