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

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

Addenda to the record of machaeridian shell plates in the Wether Law Linn Formation (Late Llandovery), Pentland Hills, Scotland
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. A new type of anterior outer shell plate is described and is compared with material previously described from...Candela, Yves ; Crighton, William R B

Notes on the brachiopod species from the Silurian of the Pentland Hills described by Lamont (1978)
Four Silurian brachiopod species from the Pentland Hills, previously ignored or designated nomina dubia, require some recognition on the basis of material identified in the collections of the National Museum of Scotland and a closer scrutiny of the published work with respect to the guidelines of the International Commission of...Candela, Yves ; Harper, David A T ; 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 …

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

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
