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.

Branching coral specimens, dated from the Devonian period, the species is known as thamnopora and belong to the tabulate form of these now extinct species. They clearly depict the colonial nature of this type, the small ‘pits’ on the surface of the coral, would have, during life, been hole, within which the coral polyps resided, emerging to feed, mate and more and retreating inside when potential danger was present. The samples were collected from the Western Sahara region of Morocco, available by weight, the pieces rang in size from 30 mm to 60 mm and come supplied in a polythene bag with an information label. Ideal for kits, sets, craft and educational use, where a numerous pieces may be required for an economical cost.
Specimens of Dinosaur Bone, collected from Abingdon, Oxfordshire in the UK. These samples are from an unidentified species, however they date to approximately 157 – 152 Ma. This puts these samples in the Kimmeridgian stage of the Jurassic period, which is the apex of the dinosaur’s rule on Earth. The specimens display a rusty brown colouration and showcase their porous bone structure. The pieces are from undetermined body parts and could be remnants from various parts of the animal. These samples are available in various sizes and come supplied in a white card tray with an information 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.
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.
