Gastropod fossils from Morocco, these high quality specimens exhibit the coiled morphology of the shell, they are from the Cretaceous period, making them between 145 to 65 million years old and likely died out during the Cretaceous/Tertiary extinction event, which also killed of the dinosaurs. The shells are approx 10 mm in size and are excellent for educational use or to put into kits of packs, they have been washed and are available in optional weights, the pieces will come supplied in a bag with a 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.
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.
Bouguetia saemanni, Large specimens around 3″ in size, some tips are not complete.
Metagabbro specimens from Lom, Central Norway. Also known as scapolite-hornblende due to the absence of feldspar in the rock are available in 3 optional sizes and come supplied in a card tray with a data 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.
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.
