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.

Flexicalymene (formally known as diacalymene) are an extinct species of trilobite which lived during the Ordovician period, 449 to 443 million years ago. They represent the typical trilobite which one would expect, with their bodies being composed of three parts, the head (cephalon), main body, (thorax) and tail (pygidium), hence the name. As with most trilobites, they lacked any form of offensive defence and instead relied upon their hard bodies to protect them, it is believed that when under threat, they may have also enrolled into a ball like shape (similar to todays woodlouse’s) or buried themselves in the sea floor sediment. The morphological features of trilobites, particularly the legs and mouth located on the underside of the animals body indicate that the animal was most likely a scavenger and bottom feeder, feeding on the falling organic matter which lands on the sea floor. Their eyes were located on the top of their heads and are believed to have allowed the animal to keep a look out for potential predators. These particular specimens come from Erfoud, Morocco and are available in various optional sizes and come in a card tray with a label.

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 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.
A colonial coral which lived in warm shallow waters and is common in the limestone rocks of the Silurian period. Heliolites is often associated with other corals that formed small reefs.

• Geological Age: Carboniferous Period
• Location: Lancashire, UK
• Family: Echinoderm
• Species: Crinoid
Crinoid stem fossils collected from Lancashire, UK. These fossil specimens from the Silurian period, exhibit the segmented nature of crinoid stems, varying between 30 to 50 mm in length and 10 to 20 mm in diameter, the samples are supplied in optional weights, making them perfect where a certain amount is needed for an economical costs, such as for schools, kits and more. The samples will come supplied in a bag with a data label.

• Geological Age: Carboniferous period
• Location: Clitheroe, Lancashire, UK
• Family: Echinoderm
• Species: Crinoid
Fossil crinoid stems from Clitheroe, Lancashire, these specimens are excellent for collectors and educational use, they are of an fairly good size where morphological details can be easily seen, ranging from 40 to 60 mm in length and varying thicknesses. They samples will come supplied in a card tray with a label.
Araneograptus murrayi fossil graptolite specimens which exhibit dendritic morphology. The samples are preserved within Fezouata shale deposits of lower Ordovician which is within the Drâa-Tafilalet region of Morocco and show the fan like structure this species had during life. A colonial animal, graptolites likely floated trough the ocean and filter fed, much similar to corals. The abundance of iron in the rock gives the shale and fossils a pale orange colouration. Graptolites themselves are important for geological dating as specific species can be used as zoning fossils to determine the age of strata, as such, these samples are not only suitable for enthusiasts but also educational use. They come supplied in a card tray with an information label.

Species Name: Bos primigenius
Geological Age: 10,000. Pleistocene period
Location: North Sea Bed, Holland
Body Part: Ankle Bone
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.
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.

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.
