Brachiopod associations from the Middle Ordovician of the Oslo Region, Norway
The marine upper Darriwilian (Middle Ordovician) Elnes Formation of southern Norway contains very rich and diverse invertebrate faunas. Stratigraphically detailed recent collections of these well-preserved faunas have permitted a more thorough description of the various faunal groups and their preferences in the late Middle Ordovician of the Oslo Region, southern...Candela, Yves ; Hansen, T.

Addenda to the record of machaeridian shell plates in the Wether Law Linn Formation (Late Llandovery), Pentland Hills, Scotland
Additional machaeridian specimens from the Wether Law Linn Formation (Telychian) have increased our knowledge of this poorly recorded but abundant group in the Pentland Hills, located a few kilometres SE of Edinburgh. A new type of anterior outer shell plate is described and is compared with material previously described from...Candela, Yves ; Crighton, William R B

Notes on the brachiopod species from the Silurian of the Pentland Hills described by Lamont (1978)
Four Silurian brachiopod species from the Pentland Hills, previously ignored or designated nomina dubia, require some recognition on the basis of material identified in the collections of the National Museum of Scotland and a closer scrutiny of the published work with respect to the guidelines of the International Commission of...Candela, Yves ; Harper, David A T ; Crighton, William R B

Revision of Plumulites ruskini Lamont, and new data from the Silurian of the Pentland Hills, Scotland
Disarticulated sclerites of plumulitid machaeridians were collected from the Wether Law Linn Formation (Telychian) in the Pentland Hills, Scotland. The specimens are described and compared to specimens collected earlier from the same horizon and locality. Other specimens from the same horizon, assigned in previous works to Turrilepas haswelli then to...Candela, Yves ; Crighton, William R B

Evolution of Laurentian brachiopod faunas during the Ordovician Phanerozoic sea level maximum
The distribution of brachiopod faunas around Laurentia during the Ordovician period was influenced by the dynamicity of the surrounding palaeo-continents. Laurentia seemed to have been somewhat static, straddling the palaeo-equator, whereas the late Ordovician was characterised by the later stages of the closure of the Iapetus Ocean, with Baltica, eastern...Candela, Yves

Synoptic revision of the Ordovician brachiopods of the Barr and Lower Ardmillan groups of the Girvan area, Scotland
The generic assignments of some 200 Ordovician brachiopod species in the Barr and Lower Ardmillan (upper Darriwilian–lower Katian) succession, Girvan are reviewed and, where necessary, modified. This key database on the distribution and occurrence of a Laurentian-marginal brachiopod assemblage has featured in many analyses of global biogeography for the period...Candela, Yves ; Harper, David A T

First record of a polyplacophoran from the Southern Uplands of Scotland
An intermediate sclerite of a paleoloricate chiton (Polyplacophora) collected from the Kirkcolm Formation (Ordovician, Lower Katian) of Kilbucho in the Scottish Borders (formerly Peeblesshire), Scotland represents the first record of the class in the Southern Uplands. The single Kilbucho specimen is morphologically distinct from documented taxa, and is described and...Candela, Yves ; Cherns, Lesley ; Troalen, Lore

Comments on the proposed conservation of the specific name of Anathyris monstrum Khalfin, 1933 (currently Anathyrella monstrum; Brachiopoda, Athyridida)(Case 3632) 4
Alvarez & Modzalevskaya presented a detailed and thorough application, in which they clarified the issues arising from Khalfin’s original works (BZN 70: 185–189; Khalfin, 1933a, 1933b, 1946) and proposed clear resolutions.Candela, Yves
