摘要
莫雷纳山脉（西班牙西南部）的下泥盆统（普拉格安-埃米西亚）暗礁沉积物中含有丰富的钙化蓝藻、钙质藻类以及包括有孔虫在内的各种微化石。钙化蓝藻以 Girvanella 属（A-C）为代表，形成各种形状的结壳和团块。假定的绿藻（?Dasycladales）有一个新属和一个新种，即 Bediaella hispanica gen.藻类包括 Vasicekia margaritula (Saltovskaya, 1986) n. comb.所研究的生物群落表明，在具有正常盐度的浅水和良好搅拌环境中存在光照和温暖条件，并可能反映了由于海平面波动而导致的浅化现象。
Palaeoecology of calcified microfossils from the Lower Devonian (Pragian-Emsian) of Sierra Morena (SW Spain)
Lower Devonian (Pragian-Emsian) reefal deposits of Sierra Morena (SW Spain) contain locally abundant calcified cyanobacteria, calcareous algae, and various microfossils including foraminifers. Calcified cyanobacteria are represented by Girvanella spp. A–C, which form crusts and clumps of various shapes. Supposed green algae (?Dasycladales) are represented by a new genus with one new species, Bediaella hispanica gen. et sp. nov. Algospongia include Vasicekia margaritula (Saltovskaya, 1986) n. comb. Microproblematica are represented by Rothpletzella sp. The studied assemblages indicate photic and warm conditions in a shallow and well-agitated environment with normal salinity, and probably mirror episodes of shallowing due to eustatic sea level fluctuations.
期刊介绍：
The journal is open to papers dealing with the interpretation of ancient and modern biotopes and carbonate depositional environments by means of facies analysis in its broadest sense. Once the central part of research in hydrocarbon exploration, facies analysis more and more integrates modern and ancient biogeological processes of a changing earth. Special emphasis is laid on paleobiology and -ecology, basin evolution, sedimentology including diagenesis and geochemistry, as well as studies emphasising the impact of life on earth history. The main part of the target group will be people in academia.
