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.

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.

• Geological Age: Late Devonian period, 372 – 358 million years old
• Location: Alnif, Morocco
• Species: Various species.
Various goniatite fossil specimens from Alnif, Morocco, supplied by weight with various options available, these hematite stained red fossils show clear suture lines, chambers and coils, they are supplied in whole and partial pieces varying between 10 to 15 mm in size. Dated to the late Devonian period, 372.2 million years ago to 358.9 million years ago these fossils were found in what is now Alnif, Morocco, an area more known for it’s dessert and heat. However, during the late Devonian period, this area was submerged, being a marine environment, in which these various species of goniatites as well as other marine dwelling fauna lived.

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.

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.
