Remarks on Bačinella Radoičić, 1959 (type species B. irregularis) and its representatives

Schlagintweit, Felix ; Bover-Arnal, Telm

In: Facies - International Journal of Paleontology, Sedimentology and Geology, 2012, p. -

Bačinella irregularis was described by Radoičić (Bull Serv Géol Géophys Rep Serbie 17:87–92, 1959) as an alga incertae sedis. Based on material from the Lower Aptian of the western Maestrat Basin (Spain), the genus Bačinella with its various species is revised; an emended diagnosis is given as well as a detailed description. Bačinella is interpreted as an organism that excavated complex...

Corals on the slope (Aptian, Maestrat Basin, Spain)

Bover-Arnal, Telm ; Löser, Hannes ; Moreno-Bedmar, Josep Anton ; Salas, Ramon ; Strasser, André

In: Cretaceous Research, 2012, p. -

The term “reef” has been frequently misused when applied to fossil coral communities. Our popular but biased view of coral community structure based on the idyllic picture of recent tropical reefs has failed to recognize that, in many fossil examples, alternative states of community structure with no or limited framework may occur. The Aptian colonial scleractinians analysed in the western...

The morphological adaptation of Lithocodium aggregatum Elliott (calcareous green alga) to cryptic microhabitats (Lower Aptian, Spain): an example of phenotypic plasticity

Schlagintweit, Felix ; Bover-Arnal, Telm

In: Facies : International Journal of Paleontology, Sedimentology and Geology, 2011, p. -

Lithocodium aggregatum Elliott is interpreted as a heterotrichale chlorophycean alga with a prostrate and erect system within a well-calcified tissue. Within Lower Aptian coral rubble of the western Maestrat Basin, Spain, it forms thick masses of juxtaposed crusts around the bioclasts. In achieving a rapid and complete encrustation of the available bioclasts, Lithocodium applied several...

Comparison of different procedures to map reference evapotranspiration using geographical information systems and regression-based techniques

Vicente-Serrano, Sergio M. ; Lanjeri, S. ; López-Moreno, Juan I.

In: International Journal of Climatology, 2007, vol. 27, no. 8, p. 1103 - 1118

This paper compares different procedures for mapping reference evapotranspiration (ETo) by means of regression-based techniques and geographical information systems (GIS). ETo is calculated following the method of Hargreaves (HG) from a dense database of meteorological stations in the northernmost semi-arid region of Europe, the Ebro valley. The HG method requires the...

Internal structure and depositional environment of Late Carboniferous mounds from the San Emiliano Formation, Cármenes Syncline, Cantabrian Mountains, Northern Spain

Samankassou, Elias

In: Sedimentary Geology, 2001, vol. 145(3-4), p. 235

Well-exposed mounds are common in limestone of the Late Carboniferous San Emiliano Formation, Cantabrian Mountains (Northern Spain). They occur as obvious primary topographic features. Careful study of the mound intervals and surrounding strata revealed the internal structures of mounds and the factors controlling their growth. The substrate (2–3 m) of the mounds consists of greyish to reddish,...
