The Fezouata brachiopod fauna: an Early Ordovician diversification at high latitudes
Brachiopods are a neglected part of the Fezouata fauna. Brachiopods occur in two distinct horizons: firstly in the lower part of the Fezouata Shale (upper Tremadocian); secondly in the upper part of the Fezouata Shale (lower Floian). The fauna is dominated by a mixture of lingulides, siphonotretides and orthides. The...Candela, Yves ; Harper, David T ; Mergl, Michal

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

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

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 …
