A confocal laser scanning and conventional wide field light microscopy study of Classopollis from the Toarcian‐Aalenian of the Fuentelsaz section (Spain)

A morphological study of three different types of dispersed Circumpolles pollen grains from the Toarcian‐Aalenian of the Fuentelsaz section (Spain) was performed using conventional wide field and confocal laser scanning microscopy (CSLM). The CSLM data allowed scanning electron microscope‐like three‐dimensional reconstructions to be made and showed that the most part of the studied pollen have taxonomic features characteristic of the Mesozoic genus Classopollis. At the species level, Classopollis torosus and Classopollis classoides were identified. The third form studied is characterized by the presence of Ubisch bodies adhering to the pollen wall.

Late Cretaceous (Late Cenomanian–Early Turonian) dinoflagellate cysts from the Castilian Platform, northern Spain

The biostratigraphical ranges, geographical distribution and taxonomy of 45 dinoflagellate cyst species are described based on the analysis of 99 samples from the Upper Cenomanian—Lower Turonian outcrop sections of Puentedey, Fuentetoba, Condemios and Tamajón in northern Spain. A specific rank for Coronifera hebospina (formerly Coronifera oceanica subsp. hebospina) and the new combination Exochosphaeridium majus are proposed. The generic assignment of Implestosphaeridium? clavulum and Implestosphaeridium? polytrichum are questioned. Early Turonian range tops for Coronifera albertii, Cyclonephelium vannophorum and Palaeohystrichophora palaeoinfusa are confirmed.
