Middle and Upper Ordovician linguliformean and craniiformean brachiopods from the Brabant Massif, Belgium: Infaunal giants, encrusting forms and durophagy
Linguliformean and craniiformean brachiopods from the Middle and Upper Ordovician of the Brabant Massif (Belgium) are described for the first time and their palaeoecological and palaeobiogeographical implications are discussed. The restricted and generally poorly preserved material was collected from the Abbaye de Villers (Dapingian–Darriwilian) Formation and from the Katian Huet...Candela, Yves ; Mottequin, Bernard

Evolutionary trends in trimerellid brachiopods
Non-articulated trimerellides, one minor group among the largest brachiopods, are commonly found in massive monospecific accumulations in Ordovician and Silurian rocks. In this paper, all species of the family Trimerellidae are listed for the first time, and some of them are discussed. They appeared in the Sandbian and became extinct...Chen, Di ; Huang, Bing ; Candela, Yves

New machaeridian data from the Upper Ordovician of Scotland: palaeoecological and global palaeobiogeographical implications
New machaeridian material housed in the National Museum of Scotland alongside the type material held in the Natural History Museum London and the Sedgwick Museum of Earth Sciences, Cambridge, is documented here from the Ordovician of Girvan. The specimens are included in four taxa, three of these in open nomenclature.... -

Revision of the Llandovery (lower Silurian) trimerellide brachiopod Yidurella in South China
Although a minor group of brachiopods in the Ordovician and Silurian, the trimerellides include some of the largest known brachiopods in the Early Paleozoic. Yidurella Zeng, a monospecific genus of moderate size from the Shamao Formation of Tizikou, Yidu City, Hubei Province, was originally described as having a solid platform....Chen, Di ; Huang, Bing ; Candela, Yves

New fossil assemblages from the Early Ordovician Fezouata Biota
The Fezouata Biota (Morocco) is a unique Early Ordovician fossil assemblage. The discovery of this biota revolutionized our understanding of Earth’s early animal diversifications—the Cambrian Explosion and the Ordovician Radiation—by suggesting an evolutionary continuum between both events. Herein, we describe Taichoute, a new fossil locality from the Fezouata Shale. This...Saleh, Farid ; Vaucher, Romain ; Vidal, Muriel ; Hariri, Khadija El ; Laibl, Lukáš …

The Ordovician diversification of sea urchins: systematics of the Bothriocidaroida (Echinodermata: Echinoidea)
The echinoids of the order Bothriocidaroida represent the initial burst of sea urchin diversification. They were the first echinoids to achieve widespread biogeographical dispersal and achieved high levels of species richness compared to other clades of stem group echinoids. Following long-standing controversy regarding their phylogenetic affinities within the phylum Echinodermata,...Thompson, Jeffrey R ; Cotton, Laura J ; Candela, Yves ; Kutscher, Manfred ; Reich, Mike …

Tremadocian and Floian (Ordovician) linguliformean brachiopods from the Stavelot–Venn Massif (Avalonia; Belgium and Germany)
Lower Ordovician linguliformean brachiopods from the Stavelot–Venn Massif (Belgium and Germany) are described systematically for the first time. The material comprises specimens from the Jalhay (Solwaster Member) and Ottré (Les Plattes Member) formations of Tremadocian and Floian ages, respectively. The Solwaster Member yielded a relatively diverse assemblage of nine species...Candela, Yves ; Mottequin, Bernard

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 …

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

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 …

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

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

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
