“…Esta extensão para o sul ocorreu antes da supremacia dos elementos malvinocáfricos, domínio biogeográfico este onde o registro deste grupo de corais varia entre raro nas regiões sul e central da América do Sul, a ausente na Antártica (Oliver Jr, 1977). O registro de Pseudochonophyllum, gênero típico do domínio do Velho Mundo na Formação Maecuru (Távora & Souza, 1999) corrobora o aspecto biogeográfico misto da sua paleofauna, já identificado com os braquiópodes e biválvios.…”

“…As faunas marinhas do Devoniano Inferior e Médio estão agrupadas em três domínios biogeográficos distintos, Malvinocáfrico (sul e centro da América do Sul, África do Sul e Antártica), das Américas Orientais (mais da metade do leste dos Estados Unidos, leste do Canadá e áreas norte e noroeste da América do Sul) e do Velho Mundo (oeste dos Estados Unidos, norte e oeste do Canadá, noroeste da África, Europa, Ásia e Austrália), onde o gênero de coral rugoso Phillipsastrea é um fóssil guia (Boucot, 1974;Oliver Jr, 1977;May, 2006a).…”

“…Entretanto, a existência de alguns gêneros de tabulados, como Parastriatopora, que foi mais abundante em latitudes equatoriais e tropicais, sugere águas mais temperadas, provavelmente oriundas das regiões africanas no norte do Gondwana (Oliver Jr, 1977;Fernández-Martínez et al, 2007;Carrera et al, 2013).…”

ResumoOs corais e briozoários devonianos brasileiros estão registrados nas bacias do Amazonas e Paraná, respectivamente nas formações Maecuru e Ponta Grossa. Na região amazônica são duas espécies de corais e oito de briozoários, enquanto na região sul e sudeste a ocorrência de ambos os grupos está limitada a citações gerais. A baixa diversidade específica e o pequeno tamanho das populações relacionam-se com limitações ecológicas, filogenéticas e preservacionais, além do número insuficiente de pesquisas específicas. Palavras-chave: Corais; Briozoários; Paleobiogeografia; Devoniano AbstractThe Devonian corals and bryozoans of Brazil are recorded in the Amazonas and Paraná basins, at Maecuru and Ponta Grossa formations, respectively. In the Maecuru unit occurs two species of corals and eight bryozoans species while at Ponta Grossa sediments only general citations of these taxa are presented. The low specific diversity and populations size are related with the ecologic, phylogenetic and preservational constraints besides insufficient number of specific searches.

“…Boucot et al (1967Boucot et al ( , 1969 set the existence of three geographic realms during the Lower Devonian, based on the distribution of brachiopods: the Malvinokafric, the Eastern Americas and the Old World Realm. Oliver (1976) and Bigey (1980) used these divisions in their biogeographic studies of Devonian rugose corals and bryozoans, respectively. The upper Emsian-lower Eifelian Moniello Formation was deposited in a carbonate platform belonging to the Rhenish-Bohemian Province of the Old World Realm, at the septentrional margin of Gondwana.…”

Lower-Middle Devonian non-fenestellid fenestrate bryozoans of NW Spain are reported, from two coastal sections of the upper Emsian-lower Eifelian Moniello Formation, the type locality at Moniello Inlet and at Arnao. Eighteen species of non-Fenestellidae fenestrates belonging to thirteen genera and six families have been identified; nine species are new: Bashkirella arnaoense, Utropora parva, Bigeyina cantabrica, B. spinosa, Fenestrapora elegans, Paraseptopora geometrica, P. irregularis, Kalvariella antiqua and Filites robustus. Fenestrates described herein, together with earlier reported taxa of the Family Fenestellidae from the Moniello Formation show palaeobiogeographic affinities with those of neighbouring Gondwanan regions, especially with Bohemia, but also with Middle Devonian assemblages from Eastern North America. The fenestrate fauna from NW Spain comprises seven species common with the Lower Devonian of the Prague Basin (Bohemia, Czech Republic) and genera with relatively limited geographic distributions, such as Utropora and Filites. A remarkable feature of the studied fauna is the presence of several species that represent the earliest and westernmost reported occurrence of their genera, Bashkirella, Paraseptopora and Kalvariella, as well as previously reported Cavernella asturica. The occurrence of these species together with the stratigraphic and geographic position of previously reported ones indicate the existence of large gaps in the distribution of these Lazarus genera.•

Silurian‐Devonian coral associations across a sequence stratigraphic boundary in the Argentine Precordillera

Silurian and Devonian corals occur abundantly in siliciclastic rocks of the Argentine Precordillera. They are distributed along a Silurian stormdominated shallow-water platform, a transitional restricted nearshore environment, and a Devonian muddy platform setting. Four main associations of rugose and tabulate corals have been recorded: a Silurian association, a lowermost Devonian and two associations in Lower Devonian rocks. The Silurian shallow-water platform coral association shows abundant colonies of a tabulate pleurodictyform coral. The type and the domical form of corals indicate high-energy environments. The lowermost Devonian coral association shows the abundance of the tabulate coral Argentinella argentina, which could have formed patches in protected low-energy environments. The Lower Devonian coral associations correspond to a muddy platform environment. The first one includes rugose and hemispherical tabulate corals and the second is composed of tabulate corals assigned to Parastriatopora sanjuanina, and Parastriatopora sp. They are long stick-like, fasciculate forms, grouped in apparently life position. Rugose and tabulate corals in the Upper Silurian and Lower Devonian of Argentina constitute lowdiversity associations of western Gondwana, developed in mid-to high-latitudes. The morphologies acquired by corals are related to water energy. Laminar or encrusting forms were more competitive in the Silurian shallow-water, high-energy environments. Slender branching forms with a high profile typically inhabited Devonian relatively deeper water or protected settings. The stratigraphic distribution observed partially followed the well-known pattern in which shallow-water faunas disappeared during regressive events and are replaced by new forms in the subsequent transgressive sequence. The turnover pattern detected across the Silurian-Devonian transitional interval is in agreement with that previously recognized on the basis of the accompanying fauna.
