This reef limestone is approximately 425 million years old from the Wenlock series of the Silurian. It was collected many years ago from Wren’s Nest, near Dudley in the West Midlands. It is a site of much renown as Wren’s Nest and Castle Hill contain superb exposures of middle Silurian (Wenlock and lower Ludlow series) rocks, including a definitive section through the Much Wenlock Limestone. The Limestone contains the most diverse and abundant fossil fauna in the British Isles: over 600 species of marine invertebrate, representing some 29 major taxonomic groups, including corals, trilobtes, , brachiopods, gastropods, bivalves & graptolites. It was quarried extensively until 1925 for use in blast furnaces & the production of lime. The locality is now a protected nature reserve.
Each specimen is supplied with a labelled card tray.

It’s characteristic appearance comes from densely packed shells of the freshwater snail Viviparus set in a lime mud matrix. It’s uses include construction as a building and decorative stone which is visible in Canterbury, Lincoln, Salisbury cathedrals & Westminster Abby to name but a few.

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.
