Date: 18-22 March 2024
Location:  Patras, Greece
Venue: University of Patras
Official Organizer: FS*IRGO - Society of Friends Förderverein für die International Research Group on Ostracoda e. V.


ESO offers a comprehensive overview on ostracodology, covering taxonomy, (palaeo)ecology, biodiversity, and applied biostratigraphy. Designed for young scientists, the focus includes systematics, biostratigraphic applications, ecology, and life history.
The course spans the Paleozoic to Holocene, with practical training and case studies enriching the learning experience.


The European School on Ostracoda (ESO) course is designed to offer a comprehensive understanding of ostracod taxonomy, (palaeo)ecology, biodiversity, geological history, and applied biostratigraphy. 
It caters to the interests of young scientists and industrial professionals engaged in micropalaeontology, palaeoceanography, palaeoclimatology, biology, and environmental applications. 
The emphasis will be on exploring the methods and principles of ostracodology, encompassing systematics, biostratigraphic applications, ecology, and life history.
The course will delve into the fossil record of ostracods from the Paleozoic to the Holocene, spanning contemporary fauna as well. Notably, the program will include case studies from both marine and continental systems, along with hands-on training in identification, preparation, documentation, and analysis.
