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

IGCP 735 (2021-2025): rocks and the rise of Ordovician life: filling knowledge gaps in the Early Palaeozoic biodiversification (Rocks n'ROL)
Deciphering the complex interactions between climate change, biodiversity and ecosystem structuration is a major societal issue for future generations. The geological record offers the unique opportunity to document the impact of environmental changes in the biosphere in the past, and thus to provide some clues for the future. In this...Lefebvre, Bertrand ; Candela, Yves ; Hariri , Khadija ; Ghobadi Pour , Mansoureh ; Raevskaya, Elena …

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

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

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
