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.

• Geological Age: Silurian period, 443 to 416 millions years old
• Location: Djebel Issoumour, Alnif, Morocco
• Family: Echinoderm
• Species: Crinoid
Crinoid stem fossils collected from Djebel Issoumour, Alnif, Morocco. These fossil specimens from the Silurian period, exhibit the segmented nature of crinoid stems, varying between 30 to 60 mm in length and 10 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.
Specimen: Horn Coral
Geological Age: Silurian, Wenlock Series
Location: Shropshire, UK
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.

Ogyginus sp fossil pygidiums from the Llanvirn series during the middle of the Ordovician period, the samples come from mid Wales in the UK and are preserved on a fine grained solid mudstone matrix. The pygidiums (tail) are available and it is believed that this is due to moulting behaviour of the animal in which it anchored its tail to the sea floor to moult its old carapace, during the process. The samples are well preserved and range between 15 t0 20 mm in size and increasingly more difficult to come by. They are ideal for both collectors and enthusiasts but also ideal for educational use to describe the animals behaviour in life, each samples will come supplied in a white card tray with an information 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.
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.

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.
