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

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.

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
