New sedimentological and paleontological information on the uppermost Moscovian and Kasimovian strata of the Las Llacerias section, a succession exposed in the Picos de Europa region (Cantabrian Mountains) that is considered to bear interest for the global correlation of the Upper Pennsylvanian subsystem, are presented. Based on sedimentological studies, three stratigraphic intervals can be established...
Maimonachaetetes hispanica nov. gen., nov. sp. is described as a primitive red alga due to the presence of a coaxial dimerous thallus composed of tiny cellular structures with occasional cell fusion. It is recorded from Asbian (Mississippian) strata at Los Santos de Maimona Basin (south-western Spain). The species shows many characters in common with the Paleozoic Archaeolithophyllum and the solenoporaceans,...
A new genus, Falsocalcifolium is described. The type species is F. punctatum (Maslov) emend. The genus is placed in the tribe Calcifolieae Shuysky emend. of the family Calcifoliaceae Termier, Termier and Vachard nomen translat. Consequently, the generic make-up of the tribe is emended, and is now considered to be composed of Frustulata Saltovskaya emend., Falsocalcifolium nov. gen., and Calcifolium...
. Analysis of the microflora from the Mississippian deposits of southwest Spain has revealed the presence of a new species: Palaepimastoporella espielensis new gen. new sp. It is assigned to the family Seletonellaceae comprising of primitive (i.e., aspondyl) dasyclads. Palaepimastoporella is one of the earliest representative of the epimastoporid-lineage, an important group of cladospore algae, widespread...
