| This circumpolar dataset of the comatulid (Echinodermata: Crinoidea) Promachocrinus kerguelensis (Carpenter, 1888) from the Southern Ocean, documents biodiversity associated with the specimens sequenced in Hemery et al. (2012). The aim of Hemery et al. (2012) paper was to use phylogeographic and phylogenetic tools to assess the genetic diversity, demographic history and evolutionary relationships of this very common and abundant comatulid, in the context of the glacial history of the Antarctic and Sub-Antarctic shelves (Thatje et al. 2005, 2008). Over one thousand three hundred specimens (1307) used in this study were collected during seventeen cruises from 1996 to 2010, in eight regions of the Southern Ocean: Kerguelen Plateau, Davis Sea, Dumont d'Urville... |

| RESUMO O registro fóssil do Devoniano do estado de Goiás (Sub-bacia Alto Garças, Bacia do Paraná) é ocorrente nos arredores de diversas cidades como Amorinópolis, Iporá, Caiapônia, Rio Verde e Doverlândia. Contudo, os fósseis encontrados em Goiás são, em sua maioria, representados por braquiópodes, comumente pertencentes aos gêneros Derbyina, Australocoelia, Australospirifer, Schuchertella, Orbiculoidea e Lingula. Embora também haja ocorrências, em menor número, de outros grupos como trilobitas, moluscos, tentaculitoideos, anelídeos, equinodermas, lycopsidas e cnidários, além dos microfósseis de quitinozoários, representados pelos gêneros Ramochitina, Ancyrochitina, Sphaerochitina, Angochitina, Conochitina, Lagenochitina e Cyathochitina. No entanto, os... |

| Dissociated skeletal elements of bourgueticrinid crinoids, comprising mostly columnals, radicular cirri, a few cups and some brachials, are recorded from Turonian-Maastrichtian strata of southern Poland (Miechów Trough, Kraków-Cze˛stochowa Upland, Holy Cross Mountains and Opole Trough). Published records of bourgueticrinids from Poland are surprisingly few; only specifically indeterminate columnals, radicular cirri and a sole proximale, plus a single cup of Bourgueticrinus utriculatus have been noted. The present material, although limited, clearly demonstrates that these crinoids must have been less rare than anticipated and are, in fact, distributed throughout the entire Upper Cretaceous sequence in this area. The majority of bourgueticrinids had an... |

| All Campanian, Maastrichtian and Danian articulate (cladid) crinoids known to date from the extendedtype area of the Maastrichtian Stage, are described and illustrated. The geographic and stratigraphicdistribution of this unexpectedly diverse echinoderm group are documented. A total of twentygenera (three of them new) and thirty-six species (six of them new) are defined: Austinocrinus bicoronatus(von Hagenow, 1840), ‘Isocrinus’ sp., ‘I.’ lanceolatus (Roemer, 1840)?, Isselicrinus buchii (Roemer,1840), Praeisselicrinus? limburgicus (Rasmussen, 1961), Nielsenicrinus agassizii (von Hagenow, 1840) (=‘Pentacrinites’ kloedeni von Hagenow, 1840), N. ewaldi sp. nov., Jaekelometra gr. belgica (Jaekel, 1902), J.gr. concava (Schlüter, 1878) (= J. columnaris Gislén,... |

| Systematic taxonomy requires thoughtful, detailed and structured descriptions of species characters, and essential additional data for effective comparison with other specimens. Crinoid terminology is commonly misused or at best confused. The purpose of this paper is to facilitate this process by encouraging a standard methodology which would make comparisons of fossil crinoid taxa easier for all. An ordered tabulation of those characters that should be considered in any description of a fossil crinoid is provided and implemented in describing a Scottish Llandovery (Lower Silurian) disparid crinoid Pisocrinus cf. campana S.A. Miller. |
