Calymene Blumenbachii
''Calymene blumenbachii'', sometimes erroneously spelled ''blumenbachi'', is a species of trilobite discovered in the limestone quarries of the Wren's Nest in Dudley, England. Nicknamed the ''Dudley Bug'' or ''Dudley Locust'' by 18th-century quarrymen it became a symbol of the town and featured on the Dudley County Borough Council coat-of-arms. ''Calymene blumenbachii'' is commonly found in Silurian rocks (422.5–427.5 million years ago) and is thought to have lived in the shallow waters of the Silurian, in low-energy reefs. This particular species of ''Calymene'' (a fairly common genus in the Ordovician-Silurian) is unique to the Wenlock series in England, and comes from the Wenlock Limestone Formation in Much Wenlock and the Wren's Nest in Dudley. These sites seem to yield trilobites more readily than any other areas on the Wenlock Edge, and the rock here is dark grey as opposed to yellowish or whitish as it appears on other parts of the Edge, just a few miles away, in ...

Wenlock Epoch
The Wenlock Epoch (sometimes referred to as the Wenlockian) is the second epoch of the Silurian. It is preceded by the Llandovery Epoch and followed by the Ludlow Epoch. Radiometric dates constrain the Wenlockian between and million years ago. Naming and history The Wenlock is named after Wenlock Edge, an outcrop of rocks near the town of Much Wenlock in Shropshire ( West Midlands, United Kingdom). The name was first used in the term "Wenlock and Dudley rocks" by Roderick Murchison in 1834 to refer to the limestones and underlying shales that underlay what he termed the "Ludlow rocks". He later modified this term to simply the "Wenlock rocks" in his book, ''The Silurian System'' in 1839. Definition and subdivision The Wenlock's beginning is defined by the lower boundary (or GSSP) of the Sheinwoodian. The end is defined as the base (or GSSP A Global Boundary Stratotype Section and Point (GSSP), sometimes referred to as a golden spike, is an internationally agreed upo ...

Wenlock Limestone Formation
The Much Wenlock Limestone Formation is a series of Silurian limestone beds that date back to the Homerian age, the later part of the Wenlock epoch.{{cite web , url=http://www.bgs.ac.uk/lexicon/lexicon.cfm?pub=WEL , title=Much Wenlock Limestone Formation , publisher=British Geological Survey , work=The BGS Lexicon of Named Rock Units , date=2013 , accessdate=11 July 2013 The formation comprises nodular to thinly bedded limestones, with variable development of reef bodies that can be found exposed at Wenlock Edge and in a small area near Dudley, England known as Wren's Nest. The formation is made up of three different members which have been classified as the Lower Quarried Limestone Member, the Nodular Beds Member and the Upper Quarried Limestone Member.Dorning, K.

Silurian England
The Silurian ( ) is a period (geology), geologic period and system spanning 23.5 million years from the end of the Ordovician Period, at million years ago (Myr, Mya), to the beginning of the Devonian Period, Mya. The Silurian is the third and shortest period of the Paleozoic Era, and the third of twelve periods of the Phanerozoic Eon. As with other geologic periods, the Rock (geology), rock beds that define the period's start and end are well identified, but the exact dates are uncertain by a few million years. The base of the Silurian is set at a series of major Ordovician–Silurian extinction events when up to 60% of marine genera were wiped out. One important event in this period was the initial establishment of terrestrial life in what is known as the Silurian-Devonian Terrestrial Revolution: vascular plants emerged from more primitive land plants, dikaryan fungi started expanding and diversifying along with glomeromycotan fungi, and three groups of arthropods (myriapods, ...

Wenlock Edge
Wenlock Edge is a limestone escarpment near Much Wenlock, Shropshire, England and a site of special scientific interest because of its geology. It is over long, running southwest to northeast between Craven Arms and Much Wenlock, and is roughly 1,083 feet above sea level. The deciduous woodland which runs along it covers much of the steep slopes of the escarpment and in parts it is very well preserved. It was featured on the 2005 TV programme ''Seven Natural Wonders'' as one of the wonders of the Midlands. Wenlock Edge contains many interesting features such as Flounders' Folly, Wilderhope Manor and Shipton Hall and waymarked walks such as the Shropshire Way and bridleways such as the Jack Mytton Way. It is a popular area for hillwalking, cycling, mountain biking and horseback rider, horseriding and is also frequented by tourists and sightseers.

Ordovician
The Ordovician ( ) is a geologic period and System (geology), system, the second of six periods of the Paleozoic Era (geology), Era, and the second of twelve periods of the Phanerozoic Eon (geology), Eon. The Ordovician spans 41.6 million years from the end of the Cambrian Period Megaannum, Ma (million years ago) to the start of the Silurian Period Ma. The Ordovician, named after the Celtic Britons, Welsh tribe of the Ordovices, was defined by Charles Lapworth in 1879 to resolve a dispute between followers of Adam Sedgwick and Roderick Murchison, who were placing the same Rock (geology), rock beds in North Wales in the Cambrian and Silurian systems, respectively. Lapworth recognized that the fossil fauna in the disputed Stratum, strata were different from those of either the Cambrian or the Silurian systems, and placed them in a system of their own. The Ordovician received international approval in 1960 (forty years after Lapworth's death), when it was adopted as an official per ...
