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.

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.

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.

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.
Species Name: Leptaena depressa
Family: Brachiopod
Age: Silurian, Wenlock Series
Location: Dudley, West Midlands, UK
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.
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.
