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.

• Geological Age: Silurian period, 443 to 416 millions years old
• Location: Djebel Issoumour, Alnif, Morocco
• Family: Echinoderm
• Species: Crinoid
Moroccan fossil crinoid stem specimens supplied in packets of 5 pieces, dated to over 400 million years old, they lived during the Silurian period and show excellent clear morphological details such as stem segments. Ideal for educational use and young collectors.
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.

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.
