|
Among freshwater Testudinoidea (sensu Gaffney & Meylan, 1988; Chelonii, Cryptodira) from the Tertiary of Western Europe, the "Palaeochelys sensu lato - Mauremys" group is defined, as is the "Ptychogasteridae " group, these groups are also re-considered in their paleobiogeographical context. Taxa from the "Palaeochelys sensu lato - Mauremys" complex, previously referred to Ocadia, Palaeochelys, Clemmys, Emys... are redefined, and new taxa are described as well as new taxa of "Ptychogasteridae". The systematics and phylogeny of the Testudinoidae are studied, various phylogenies (Hirayama, 1985; Gaffney & Meylan, 1988) are discussed, new hypotheses are suggested. Two analyses of parsimony are made with 30 terminal taxa for the "Palaeochelys sensu lato - Mauremys" group and two outgroups (Platysternon megacephalum and Elkemys australis); 54 anatomical characters are described. An alternative hypothesis of phylogenetic relationships (not computerized) is proposed. An updated catalogue of the French Tertiary localities bearing chelonians is provided. The biostratigraphic and paleobiogeographical distribution of the various continental chelonian groups is studied, showing the palaeoenvironnemental and paleoecological significance of chelonians and the limits of their biostratigraphic significance.
