Dear nannofriends, a colleague is looking for a coccolith-sphere in 3D on a free downloable ressource (citation will be done obviously) for public communication. If you have any resource to share, let me know :) Thanks, Baptiste -- Baptiste Suchéras-Marx Maître de conférences CEREGE UM 34, OSU Pythéas, Aix–Marseille université https://sites.google.com/site/baptistesucherasmarx/ https://paleorhodania.wixsite.com/paleorhodania
