Storm-induced community Dynamics in the Fezouata Biota (Lower Ordovician, Morocco)
In the Central Anti-Atlas (Morocco), the lower part of the Fezouata Shale has yielded locally abundant remains of soft-bodied to lightly sclerotized taxa, occurring in low diversity assemblages characterized by strong spatial and taxonomic heterogeneities, and frequently, by the occurrence of small-sized individuals. Size frequency analyses of Celdobolus sp., Wosekella...Saleh, Farid ; Candela, Yves ; Harper, David A T ; Polechová, Marika ; Lefebvre, Bertrand …

A new hexactinellid sponge from the Silurian of the Pentland Hills (Scotland) with similarities to extant rossellids
The Pentland Hills sponge fauna (Llandovery, Telychian) consists of an unusual, aberrant assemblage, but of low diversity. A new specimen of a unique sponge, Eoghanospongia carlinslowpensis gen. et sp. nov., is described from the classic locality of R82. The mushroom-shaped, probably stalked body (peduncle attachment to body not exposed) resembles...Botting, Joseph P ; Candela, Yves ; Carrió, Vicen ; Crighton, William R B

Synoptic revision of the Silurian fauna from the Pentland Hills, Scotland described by Lamont (1978)
Archibald Lamont (1907-1985) sampled the North Esk Inlier Silurian fauna for almost 30 years. He had amassed a substantial fauna that has been, in part, bequeathed to the National Museums Scotland after his death. Unfortunately, the descriptions of the faunas in his last opus were careless and the illustrations were...Candela, Yves ; Crighton, William R B

Late Ordovician brachiopod faunas from Pomeroy, Northern Ireland: a palaeoenvironmental synthesis
Comparisons of the Caradoc assemblages with North American biofacies indicate that the Bardahessiagh Formation was deposited during a transgressive regime, which peaked with the presence of a typical Sericoidea association (member (II)). These diverse and exceptionally preserved faunas lived below the storm-wave base. The assemblages also contained a shallower water...Candela, Yves

Statistical comparisons of late Caradoc (Ordovician) brachiopod faunas around the Iapetus Ocean, and terranes located around Australia, Kazakhstan and China
Statistical comparisons, based on 173 genera distributed in 27 Caradoc localities from around the world, show strong faunal similarities between North and South China and the Chu-Ili terrane, the Chingiz terrane and Australia/Tasmania. The Scoto-Appalachian fauna of the Laurentian terrane shows closer similarities to faunas from the Gornoi-Altai terrane (belonging...Candela, Yves

Late Ordovician (Katian) brachiopods from the Southern Uplands of Scotland: biogeographic patterns on the edge of Laurentia
Some 40 brachiopod species are known from the localities of Kilbucho and Wallace’s Cast in the Kirkcolm Formation in the Northern Belt of the Southern Uplands of Scotland. The fauna is diverse despite the relatively small numbers of brachiopod specimens (c. 180) available for study. Much of the fauna was...Candela, Yves ; Harper, David A T

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.

Phylogenetic relationships of leptellinid brachiopods
The relationships among the diverse genera comprising the family Leptellinidae (Brachiopoda) are reviewed in the light of the revised edition of the Treatise on Invertebrate Palaeontology. Taxonomic work reassessed all the genera identified as Leptellinidae in the most current classification. Four genera were discarded, namely Bekkerella, Benignites, Leptastichidia and Nikitinamena....Candela, Yves

A systematic revision of the Ordovician plectambonitoidean brachiopods Chonetoidea and Sericoidea
The revised Treatise on Invertebrate Paleontology, part H: Brachiopoda regards Chonetoidea Jones and Sericoidea Lindström synonymic, on the basis of characters that were considered common to both genera (e.g. ornament type, number of septules). However, some features (e.g. number of septules) discriminate specimens at species level, rather than at generic...Candela, Yves

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

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

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

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

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

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.

New linguliformean brachiopods from the lower Tremadocian (Ordovician) of the Brabant Massif, Belgium, with comments on contemporaneous faunas from the Stavelot-Venn Massif
Lower Ordovician brachiopod macrofaunas in Belgium (Avalonia) are seldom collected and studied due to the poor preservation of material. Here we describe a new fauna of linguliformean brachiopods from the Chevlipont Formation (lower Tremadocian) in the Brabant Massif. The fauna is of low diversity (at least three species belonging to...Candela, Yves ; Marion, Jean-Marc ; Servais, Thomas ; Wang, Wenhui ; Wolvers, Mark …
