European Conference on Echinoderms are rare opportunities to bring together scientists from different countries, disciplines and generations, in one meeting dedicated to both extant and extinct echinoderms. The 11th edition will take place in France. It will include a pre-conference excursion (Oct., 11-15) to the Villefranche-sur-Mer marine station (close to Nice, on the French riviera), 4 days of indoor sessions in Lyon (Oct. 16-17, 19-20), and one mid-conference excursion to Ardèche, including the visit of the Callovian (Middle Jurassic) La Voulte Lagerstätte. This long-awaited meeting will be the first 'in person' echinoderm meeting after an almost four-year hiatus due to the covid pandemics.
