Short summary
We give closure on the study cycle of turtle material from Vic area, Middle–Late Eocene, Ebro Basin, Catalonia, Spain. Numerous comparisons with poorly known taxa are carried out, including a first description of the Eochelone shell via E. voltragana. Different swimming evolutionary states and different cheloniid subgroups Osonachelus and Eochelone are described, as well as dispersion Gondwanan forms from Africa and around European coasts.
