Inventory and analysis of the distribution of Viséan corals from the Guadiato Area (Córdoba, SW Spain)

Abstract

The coral content of the Viséan rocks from the Guadiato Area (SW Spain) have been studied during the last 25 year. Part of the coral assemblages have been previously described, but never as whole. The 69 recorded coral species belonging to Rugosa, Tabulata and Heterocorallia are illustrated. The family Antiphyllidae is represented by two genera and three species; the family Laccophyllidae, Plerophyllidae and Polycoeliidae is represented by one species; the family Cyathaxoniidae is represented by one genus and two species; the family Amplexidae is represented by one species; the family Zaphrenotididae is represented by one species; the family Cyathopsidae is represented by four genera and five species; the family Bothrophyllidae is represented by one species; the family Aulophyllidae is represented by nine genera and ten species; the family Palaeosmiliidae is represented by four genera and four species; the family Lithostrotionidae is represented by five genera and sixteen species; the family Axophyllidae is represented by three genera and thirteen species; the family Geyerophyllidae is represented by one species; the family Heterophyllidae is represented by two genera and two species; the family Syringoporidae is represented by one species; the family Multithecoporidae is represented by one genus and three species; the family Syringolitidae is represented by one species; the family Pyrgiidae is represented by one species. The degree of abundance and diversity is regarded as moderate and the degree of endemism is low. The significance of the coral assemblages for biostratigraphy, palaeobiogeography and environmental palaeontology is analysed

New species of the rugose coral genus Lithostrotion Fleming in the upper Viséan from the Azrou-Khenifra Basin (Morocco)

“…It has not been recorded in other studied basins from North Africa (Fig. 1a), such as Jerada (Aretz, 2010), Tindouf (Rodríguez et al, 2013a, b), Tafi lalt (Aretz et al, 2013) and Béchar (Semenoff-Tian-Chansky, 1985;Aretz, 2011) or in West European regions (Poty, 1981(Poty, , 1984Mitchell, 1989;Somerville, 1997;Rodríguez et al, 2002;Denayer et al, 2011;Rodríguez et al, 2016b). Consequently, the new species must be regarded at present as endemic in the Azrou-Khenifra Basin.…”

Foraminifers in upper Viséan–lower Serpukhovian limestones (Mississippian) from South Wales: regional correlation and implications for British foraminiferal zonal schemes

“…In Ireland, the species is first recorded from the late Asbian and in southern Spain it is first recorded from the uppermost late Asbian (Rodríguez et al 2016). In the Gower Peninsula, Bibradya inflata is only recorded in the late Asbian (Fig.…”

A new early Visean coral assemblage from Azrou-Khenifra Basin, central Morocco and palaeobiogeographic implications

“…The early Visean species S. hettonensis (Wilmore 1910) and S. gigantea (Michelin 1843) show also low development of lonsdaleoid dissepiments, but much larger size and number of septa than S. khenifrense (Fig. 5b).The late Visean and Serpukhovian species S. samsonensis (Salée 1913) (= S. benburbensis Lewis 1927) from Western Europe and North Africa (Smyth 1925;Hill 1938;Dixon 1970;Hubbard 1970;Semenoff-Tian-Chansky 1974Poty 1981;Poty and Hannay 1994;Somerville 1997;Said 2005;Rodríguez and Somerville 2007;Aretz 2010Aretz , 2011Denayer et al 2011;Rodríguez et al 2012Rodríguez et al , 2013Rodríguez et al , 2016bSaid et al 2013) differs by its larger dimensions, greater number of major septa and short discontinuous minor septa. The only caninoid coral described in the early Visean from the High Atlas is Caninophyllum skouraense Poty in Izart et al 1989, which shows clear differences with Siphonophyllia by the presence of very thick and long septa and absence of lonsdaleoid dissepiments.…”
