Late Albian Scleractinian corals from the Prebetic Zone (SE Spain)

摘要

From the Prebetic Zone (South-East Spain) the first Late Albian western Tethys shallow marine coral fauna is described. It encompasses 35 species in 28 genera of the suborders Amphiastraeina, Faviina, Heterocoeniina, Microsoleniina, Poritina, Rhipidogyrina, and Stylinina including two new genera (suborder Heterocoeniina) and six new species. The family Elasmocoeniidae Duncan, 1884, within the suborder Heterocoeniina is reintroduced. It encompasses all genera with a bilateral septal symmetry formerly assigned to the Heteroeniidae family. Two genera oPthis family - Pleurodendron and Heteropistophyllum - are described as new. The type species of Pleurodendron, Pleurodendron prebeticum, is new, whereas Heteropistophyllum is based on Pseudopistophyllum quinqueseptatum Turn?ek & Buser, 1976. Both genera are known from other localities older than the study area. The fauna contains the last indication of the Amphiastreid genera Aulastrea, Metaulastrea and Mitrodendron, whose last occurrence was previously known as being Aptian. This finding extends the range of the Amphiastraeina suborder until the Late Albian. The fauna encompasses more species that are known from the Aptian and Early Albian than species that have been previously found in the Cenomanian. Also the generic composition of the fauna is similar to Early Cretaceous faunas. For the Late Cretaceous and Tertiary genus Actinacis the study area represents the first occurrence, including the first ever occurrence of the suborder Poritina.
