The 17th International Symposium on Ostracoda was held in Rome (Italy), organized by Elsa Gliozzi, Ilaria Mazzini and a very industrious team of Italian ostracodologists behind them. Scientific contributions to this meeting have been published as a special issue in the journal Palaeogeography, Palaeoclimatology, Palaeoecology, as a special section in Vol 54 (2015) of the Journal of Archaeological Science and in the journal Micropaleontology. Ilaria Mazzini wrote a detailed report after the symposium.
