“…The Scottish specimens lack details of the muscle scar, and their assignment to Carbonita is tentative. Carbonita bairdioides (Jones & Kirkby, 1879b) (lectotype designated here as NHM I 2566, fig. d in Athersuch et al 2009) is distinguished by its subtriangular, asymmetrical, lateral carapace outline and arched dorsal margin (Fig.…”

Ostracods from freshwater and brackish environments of the Carboniferous of the Midland Valley of Scotland: the early colonization of terrestrial water bodies

-The Mississippian Strathclyde Group of the Midland Valley of Scotland yields some of the earliest non-marine ostracods. The succession records shallow marine, deltaic, estuarine, lagoonal, lacustrine, fluvial and swamp environments representing a series of staging-posts between fully marine and limnetic settings. Macrofossils and ostracods are assigned to marine, marginal marine, brackish and freshwater environments based on their faunal assemblage patterns. Key brackish to freshwater ostracods are Geisina arcuata, Paraparchites circularis n. sp., Shemonaella ornata n. sp. and Silenites sp. A, associated with the bivalves Anthraconaia, Carbonicola, Cardiopteridium, Curvirimula, Naiadites, the microconchid 'Spirorbis', Spinicaudata and fish. Many Platycopina and Paraparchiticopina ostracods are interpreted as euryhaline, which corresponds with their occurrence in marine to coastal plain water bodies, and supports the 'estuary effect' hypothesis of non-marine colonization. The success of non-marine colonization by ostracods was dependent on the intrinsic adaptations of ostracod species to lower salinities, such as new reproductive strategies and the timing of extrinsic mechanisms to drive non-marine colonization, such as sea-level change. The genus Carbonita is the oldest and most common freshwater ostracod, and went on to dominate freshwater environments in the Late Palaeozoic.

The first known fossil Ostracoda were collected by the Rev. David Ure from the Carboniferous Limestone of East Kilbride. In 1793 he figured his specimens, describing them merely as “microscopic shells.” Some years later Dr S. Hibbert (1836) described and figured as Cypris scotoburdigalensis some Ostracoda he had collected from the Burdiehouse Limestone near Edinburgh. The most important work on this group of fossils was done by T. R. Jones. In 1866, together with J. W. Kirkby, he gave a short account of previous research, and from 1855 until 1901 published a large number of papers, either alone or in collaboration with J. W. Kirkby, H. B. Holl and others, mainly in the Annals and Magazine of Natural History. In 1927 Dr Hopkins used an ostracod bed for correlation purposes in the Northumberland and Durham Coalfield, and in 1931 W. B. Wright observed that the ostracods show a definite succession of forms. A new species described by Wright as Cytherella foveolata occurs at the top of the Pulchra Zone and may be of zonal significance since it has not so far been recognised in any other horizon.
