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.

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.
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.

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.
Stunning peridotite thin section exhibiting the bright and beautiful colours of olivine and pyroxene punctuated by relatively abundant plagioclase. Peridotite is a dense, coarse grained, ultramafic igneous rock consisting largely of olivine and pyroxene.

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.
Pumice specimens from the Lipari islands, Italy. Pumice is an igneous rock with a highly porous structure resulting from trapped gas bubbles as the lava was being ejected. The rock is usually very light & buoyant in water. Specimens are supplied in a card tray with label.
We also supply Pumice thin sections for microscope study which are available to buy HERE.

• Geological Age: Devonian period, 419 to 358 millions years old
• Location: Morocco
• Family: Brachiopod
• Species: Atrypa sp.
Atrypa specimens found in Morocco, these brachiopod fossils are supplied in various optional weights, they measure 1 to 2 cm in size and show excellent details such as shell form, shape, ribbing and more. The amounts received will vary depending on the weight purchased, the samples will come supplied in a polythene bag with an information label. Ideal for economical purchasing, where large amounts are required for little costs, such as for gift packs, crafts and educational use.
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.
