Evolución de las asociaciones de foraminíferos planctónicos del tránsito Eoceno inferior-Eoceno medio en la Península Ibérica (Agost, Cordillera Bética y Anoz, Pirineos)
The study of planktic foraminifera assemblages across the Early/Middle Eocene in the Anoz and Agost sections allows to recognize the following biozones and subzones: Acarinma pentacamerata Biozone, Subbotina boweri Subzone and Truncorotaloides praetopilensis Subzone, in the Early Eocene, and Hantken...

| Resumo: | The study of planktic foraminifera assemblages across the Early/Middle Eocene in the Anoz and Agost sections allows to recognize the following biozones and subzones: Acarinma pentacamerata Biozone, Subbotina boweri Subzone and Truncorotaloides praetopilensis Subzone, in the Early Eocene, and Hantkenina nuttalli Biozone, Hantkenina nuttalli Subzone and Clobigerapsis subconglobata Subzone in the Middle Eocene. The quantitative study shows one warning trend across the Early/Middle Eocene boundary |
