Rough orthoceras fossil shells from Morocco, these excellent samples depict the ever popular cephalapod shell, a type of squid, in their natural unpolished state, also exhibited are the segments which make up the shell, each one being a separate gas filled chamber of the animal when it was alive. They range in size from 30 to 60 mm with occaisonal larger pieces, they are dated to the Ordovician period, making them approximately 488 million years old and were collected from the limestone deposits of Erfoud, Morocco.Available in various weights which is ideal for educational use, kits and packs allowing you to obtain more pieces for your money, they samples will come supplied in a polythene bag with a label.

Excellent examples of bivalve fossil specimens which show the shells have been agatised, giving them an orange almost semi transparent colour and vitreous lustre, the morphology of the shells have been preserved very well as agate weather or deteriorates almost not at all as opposed to other minerals at the surface. The shells are between 20 to 40 mm in size and come from Morocco, unfortunately, for the time being, we do not have much more information regarding them such as specific species or age. But the unique agatisation of the samples makes them much more interesting to observe. Supplied in lots of 5 pieces, they come packaged in a polythene bag with information label.
Snowflake obsidian is quite striking in appearance. It is characterised by the inclusion of radially clustered crystals of cristobalite, which when viewed at a glance, appear like snowflakes on the surface of the rock. These crystal clusters are set in an otherwise black vitreous matrix of obsidian, which is an naturally occurring volcanic glass, even exhibiting a conchoidal fracture. Cristobalite is a high temperature polymorph of silica, it can form as a result of the devitrification of the obsidian. These specimens come from Java, Indonesia and are supplied in card trays, sizes which are optional, each tray also has a small data label supplied.
We also supply Snowflake Obsidian thin sections for microscope study which are available to buy HERE.
• Geological Age: Cretaceous period, 145 to 65 million years ago.
• Location: Morocco
• Family: Gastrpod
• Species: Unknown – Sea Snail
High quality gastropod fossil shells from the Cretaceous period, collected from Morocco, these specimens exhibit excellent morphological detail, the shell shape and coil are seen clearly, samples are 10 mm in size and supplied in optional weights and will come in a bag with a label.
Peridotite, found in Finland, is a dense, coarse grained igneous rock. It is commonly used in saunas due to certain porpertie. These rock specimens are ideal teaching aids or collectors specimens. Supplied in a card tray with label, offered in 3 optional sizes.
We also supply Peridotite thin sections for microscope study which are available to buy HERE.

• Geological Age: Devonian period,419 to 320 million years old.
• Location: Assa, Morocco
• Family: Bivalve
Pelecypod (bivalve) fossil specimens dating back to the Devonian period, these 400 million year old samples are supplied by weight and are ideal for educational purposes, they are 20 mm in size, orange in colour and show excellent morphological details. Supplied in a polythene bag with an information label.
Accretionary lapilli tuff is an igneous pyroclastic rock, these samples come from Longsleddle, Cumbria in the UK and forms when hot ash and debris is ejected from as volcano. Some of this material is held together by moisture and once heavy enough, falls into the ash below forming small ‘spots’ within the material, creating a speckled rock. The samples are suitable both for young and serious collectors as well as educational use and are supplied in various sizes with a card tray and label.

Star Crinoid stems, collected from Morocco. These excellent fossil specimens show the stems of crinoids, a species of echinoderms, similar to brittle stars and star fish from the Silurian period. They show the segments which make up the stem very well, with each segment measuring approximately 1cm in length. Crinoid stems are a useful zoning fossil, these samples are supplied by weight, ideal for educational use, kits, packs and more, where a quantity of them may be required without costing too much. These crinoid stems are an example of a species called pentacrinites, and display a unique star shape. Collected from Morocco, the pieces will come supplied in a polythene bag 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.
Rhyolite Felsite, a highly felsitic composed variation of Rhyolite, found in Fife, Scotland, an extrusive igneous rock composed of sodium, quartz and feldspar, thus often having a pale white to pink colouration. Available in various sizes and supplied in a card tray with an information label.

Obsidian is a naturally occurring volcanic glass derived from a rapidly cooled high silica lava. Often associated with the margins of Rhyolitic lava flows. It has little or no discernable crystalline structure. Specimens are supplied in a polythene bag in lots of 1 kg with a label.
Specimens of Limestone, collected from Derbyshire. Limestone is a common, well known sedimentary rock. It consists of the calcium-rich shells, bones, and skeletons of the fauna that dominated during that period. It was laid down approximately 350 million years ago in semi tropical seas and comes from the Dinantian epoch of the Lower Carboniferous. This rock is very pure, about 98% soluble in rainwater (over time) leaving only residual clay. Its uses include aggregate, building stone, the manufacture of cement, paper & calcium carbide. Available in various sizes, each piece comes supplied in a white card tray with information label.
We also supply Limestone thin sections for microscope study which are available to buy HERE.
