ROCKS, MINERALS AND FOSSILSRock specimens available in this section. We are the UK’s leading supplier of rock specimens, by single specimens of various sizes to rocks supplied by weight in lots of 1 kg. With over 30 years years experience and 3 geologists in our warehouse, we will have what you require. Geological rock specimens are ideal for educational & private use & in collections as well as being an important part of education both with science and in geological or earth science specific subjects. Our rocks specimens are sourced from around the world, and in some cases, the majority of UK & Norwegian samples are collected by our staff members them selves.
STORAGE AND DISPLAYStorage items such as specimen trays and die cut boxes can be found here such as folding card trays, boxes and cell sections. These items will allow you to safely store you geological rock, mineral or fossil specimens and collections to prevent them from damage, dust and corrosion.

BOOKS AND GUIDESEntire range of Geological maps of the British isles produced & published by the British Geological Survey (BGS). Geological maps are often in 1:50 000 scales and are set out similar to OS maps, but instead details the geology of the local area from the bedrock to recent superficial deposits. We also stock the full range of 1:25 000 scale maps as well as even smaller scales. All maps are supplied folded for ease of use in the field.

Araneograptus murrayi £2.00 ex VAT
Araneograptus murrayi fossil graptolite specimens which exhibit dendritic morphology. The samples are preserved within Fezouata shale deposits of lower Ordovician which is within the Drâa-Tafilalet region of Morocco and show the fan like structure this species had during life. A colonial animal, graptolites likely floated trough the ocean and filter fed, much similar to corals. The abundance of iron in the rock gives the shale and fossils a pale orange colouration. Graptolites themselves are important for geological dating as specific species can be used as zoning fossils to determine the age of strata, as such, these samples are not only suitable for enthusiasts but also educational use. They come supplied in a card tray with an information label.

Diorite £2.25 – £6.00 ex VAT
Diorite rock specimens from Cockermouth, Cumbria, is an intrusive igneous rock from the Ordovician period with a coarse, phaneratic texture composed of plagioclase feldspar, biotite mica as well as hornblende with intermediate chemistry. Found with the Skiddaw group, the rock samples are more suited for serious collectors and higher level education to describe the chemistry and mineralogy of various igneous groups. Available in 3 sizes and supplied in a card tray with an information label.

We also supply Diorite thin sections for microscope study which are available to buy HERE.

Flexicalymene £3.00 – £4.50 ex VAT
2" x 2"3" x 2"
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.
- Class: Trilobata
- Species: Flexycalymene sp.
- Age: Ktaoua-Formation, Devonian period, 449 to 443 million years old
- Location: Erfoud, Morocco

Ogyginus sp. pygidium £3.00 – £5.00 ex VAT
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.
- Class: Trilobata
- Species: Ogyginus sp.
- Age: Llanvirn series, middle Ordovician period
- Location: Mid Wales, UK.

Volcanic Tuff £2.25 – £6.00 ex VAT
Tuff from the Borrowdale Volcanic Group, Ordovician in age, the rock has a green colouration to it and a slate like cleavage, hence sometimes being known as volcanic slate, green slate or Borrowdale slate. Rock specimens are available in 3 optional sizes and will come supplied in a card tray with a label.

We also supply Volcanic Tuff thin sections for microscope study which are available to buy HERE.
