The name Carboniferous means "coal-bearing", from the Latin carbō ("coal") and ferō ("bear, carry"), and refers to the many coal beds formed globally during that time. [8] The first of the modern "system" names, it was coined by geologists William Conybeare and William Phillips in 1822, [9] based on a study of the British rock succession.
Carboniferous Limestone is a hard sedimentary rock made largely of calcium carbonate. It is generally light-grey in colour. It was formed in warm, shallow tropical seas teeming with life. The rock is made up of the shells and hard parts of millions of sea creatures, some up to 30 cm in length, encased in carbonate mud.
The Mississippian (/ ˌ m ɪ s ɪ ˈ s ɪ p i. ə n / MISS-iss-IP-ee-ən), [5] also known as Lower Carboniferous or Early Carboniferous, is a subperiod in the geologic timescale or a subsystem of the geologic record. It is the earlier of two subperiods of the Carboniferous period lasting from roughly 358.9 to 323.2
The Marros Group is the name given to a suite of rocks of Namurian age laid down during the Carboniferous Period in South Wales.These rocks were formerly known as the Millstone Grit Series but are now distinguished from the similar but geographically separate rock sequences of the Pennines and Peak District of northern England and northeast Wales by this new name.
The next sub-stage of the Namurian succession is the Marsdenian and it is to this that the Chatsworth Grit, Huddersfield White Rock, Holcombe Brook Grit, Greta Grits, Roaches Grit, Ashover Grit, Gorpley Grit, Pule Hill Grit, Fletcher Bank Grit, Brooksbottom Grit, Five Clouds Sandstones and Sheen Sandstones are assigned.

The Dinantian is a series or epoch from the Lower Carboniferous system in western Europe between 359.2 and 326.4 million years ago. [1] It can stand for a series of rocks in Europe or the time span in which they were deposited.
Carboniferous Limestone – Limestone deposited during the Dinantian Epoch of the Carboniferous Period; Coquina – Sedimentary rock that is composed mostly of fragments of shells; Coral rag – Limestone composed of ancient coral reef material; Chalk – Soft carbonate rock; Fossiliferous limestone – Limestone containing fossils
