A New Species

AbstractMany of the most diverse clades of Late Palaeozoic echinoids (sea urchins) originated in the Devonian period. Our understanding of diversity dynamics of these Late Palaeozoic clades are thus informed by new systematic descriptions of some of their earliest members. The Proterocidaridae are a diverse and morphologically distinct clade of stem group echinoids with flattened tests and enlarged adoral pore pairs, which are first known from the Upper Devonian. We herein report on a new species of Hyattechinus, Hyattechinus anglicus n. sp., from the Upper Devonian of the North Devon Basin, Devon, UK. This is the first Devonian Hyattechinus known from outside of the Appalachian Basin, USA, and provides novel information regarding the palaeogeographic and stratigraphic distribution of proterocidarids in Late Devonian times. We additionally update the stratigraphic distribution of Devonian Hyattechinus from the Appalachian Basin, following recent biostratigraphic resolution of their occurrences. Hyattechinus appears to have been present in the Rheic echinoderm fauna during Late Devonian times, and comparison of the palaeoenvironmental setting of Hyattechinus anglicus with that of other Hyattechinus from the Famennian of the Appalachian Basin suggests that the genus may have preferred siliciclastic settings. Furthermore, this new taxon increases the diversity of echinoids from the Upper Devonian of Devon to three species.

AbstractMonelasmina, previously known only from the Frasnian of Europe, is described and figured from the Hay River formation (Frasnian) of the Northwest Territories, Canada. The specimens are referred to a new species, M. besti.

Selection Of

Tropical shallow-water deposits of the Refrath Formation (topmost Lower to lower part of Middle Frasnian) of the Bergisch Gladbach area (Rhenish Massif, Germany) yielded diverse, well-preserved shelly faunas. New collections show that there are in total over 30 brachiopod species, of which the Atrypida, Rhynchonellida, Spiriferida, and Athyridida orders are the most dominant groups. Serial transverse sections show that Pseudoatrypa schroeteri possesses small dental cavities, and their spiralia have a whorl number ranging from 12–13 in ca. 29–30 mm wide specimens to 15–16 in ca. 32–33 mm wide specimens. Desquamatia (Seratrypa) pectinata has slightly more numerous spiralial whorls, from 14–15 in ca. 27 mm wide specimens to 18 in ca. 35 mm wide specimens. A new species, Desquamatia (Seratrypa) refrathensis , is described based on material from the Refrath Formation in Refrath, near Köln (Cologne), east of the Rhine River, Germany. It includes finely ribbed, longer than wide, moderate- to large-sized shells of Desquamatia , which possess tiny dental cavities to nuclei and 20–21 spiralial whorls in ca. 30 mm wide and long specimens.

A New Species

The genus Phaneropleuron was instituted by Professor Huxley, in 1869, for the reception of that singular fish P. Andersoni, from the Upper Devonian Yellow Sandstone of Dura Den, in Fifeshire, which species was also subsequently described by him in the tenth Decade of the Geological Survey, published in 1861. In the present communication 1 have to add a second species, from the Lower Carboniferous strata (Burdiehouse Limestone) of Edinburghshire, by which our knowledge of the genus is thus certainly carried a stage further unwards in the geological series.

A New Species

A new species of phyllocarid arthropod, Tropidocaris salsiusculus, is described from the Upper Devonian Hampshire Formation near Rowlesburg, West Virginia. The organism was found in association with numerous trace fossils, at least one of which could have been produced by T. salsiusculus, and body fossils, including Lingula sp., several bivalve mollusks and smooth ostracods. Collectively, these organisms suggest a brackish-water environment of deposition. This report represents only the third record of phyllocarids from West Virginia.
