Abstract
Brachiopods from the Ordovician of southern Belgium (Avalonia): the end of a terra incognita
Contrary to the well-exposed Devonian–Carboniferous rock sequence, the thick siliciclastic Cambrian–Silurian succession of Belgium is poor in macrofossils and, more especially, in brachiopods. These rocks mostly crop out in the Brabant and the Stavelot–Venn massifs, and in the Condroz Inlier. Occurrences of Ordovician brachiopods have been reported since the second...Mottequin, Bernard ; Candela, Yves

Probing the deep shelf: a Lagerstätte from the Upper Ordovician of Girvan, southwestern Scotland
A deep-water Konservat Lagerstätte from the lower Caradoc (Sandbian) at Girvan is dominated by the trilobite Diacanthaspis trippi, the carpoids Anatifopsis n. sp.? and a new genus of ctenocystoid together with the polyplacophoran Solenocaris solenoides and the brachiopod Onniella williamsi. Most of these are multi-element organisms, with many specimens preserved...Stewart, Sarah E ; Owen, Alan W

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

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

The youngest ctenocystoids from the Upper Ordovician of the United Kingdom and the evolution of the bilateral body plan in echinoderms
During the early Palaeozoic, echinoderm body plans were much more diverse than they are today, displaying four distinct types of symmetry. This included the bilateral ctenocystoids, which were long thought to be restricted to the Cambrian. Here, we describe a new species of ctenocystoid from the Upper Ordovician of Scotland...Rahman, Imran A ; Stewart, Sarah E ; Samuel, Zamora

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
