Julien Claude & Haiyan Tong, Early Eocene testudinoid turtles from Saint Papoul, France, with comments on the early evolution of Testudinoidea. Oryctos 5, 3-45
The description of three Early Eocene fossil turtle species from southern France illustrates the early Eocene radiation of Testudinoidea, the largest group of recent turtles. Two species of Geoemydid Palaeoemys Schleich,1994, P. testudiniformis (Owen, 1842) and P. hessiaca Schleich, 1994, are described on the basis of new shell material from the Ypresian (Early Eocene) locality of Saint Papoul (Aude, France). A new species belonging to the family Testudinidae, Achilemys cassouleti, is interpreted as the most primitive taxon of this family. In order to assess their phylogenetic relationships, an evolutionary scenario is proposed mainly on the basis of newly published studies in molecular phylogeny, followed by paleobiogeographical considerations, and by reappraisal of morphological character evolution. Keywords: Early Eocene, Southern France, Testudines, Cryptodira, Testudinoidea, Palaeoemys, Achilemys, Phylogeny
