Late Eocene deposits of the Samlat Formation, south of Ad-Dakhla city, southwestern Morocco, have yielded a mixed marine and terrestrial vertebrate fauna. Abundant and diversified chondrichthyans and archaeocete whales have been found, as well as the remains of sirenians and proboscideans. Here we describe the rest of this fossil assemblage which i...

We report on the earliest modern Testudo from the late Miocene (Vallesian, MN 10) of the hominoid locality, Ravin de la Pluie (RPl), Greece. The material corresponds to a small nearly complete carapace owning a well distinct hypo-xiphiplastral hinge, which supports the sensu stricto generic assignment. This new terrestrial testudinid specimen is ch...

The Erymnochelys group is a lineage of Erymnochelyinae, pleurodiran turtles that originated in Africa, with a fossil record extending from the Late Cretaceous. It is currently represented by a single species, the Malagasy Erymnochelys madagascariensis. Information on most of its fossil representatives is sparse. In fact, the oldest unambiguous gene...

The phosphates of Morocco range over a period of about 24 million years (m.y.), from the end of the Cretaceous (Maastrichtian) up to the base of the Middle Eocene (Lutetian), which is the longest interval of all phosphate deposits from the Mediterranean and Atlantic “Phosphogenic Provinces”. These marine sediments have recorded the evolution of lif...

Notosuchians from Cretaceous continental environments of Gondwana have developed an unexpected array of morphologies comparable to mammals and their extinct relatives. However, this exceptional diversity is unbalanced, with South America holding nearly three times the generic diversity of Africa-Madagascar. With the exception of the triconodonts an...

Neochelys is a European Eocene genus of turtles well represented by various species. It is one of the few members of Pleurodira identified during the Cenozoic of this continent. However, it has generally been recognized only by shells, and too few skulls are known to provide useful data for comparative diagnosis and relationships. The European Eoce...

Crocodilian remains from the late Palaeocene continental locality of Mont de Berru (Marne, France) offer the opportunity to reassess the taxonomic identity of the oldest diplocynodontid from Europe. Owing to significant morphological differences from previously described species of Diplocynodon, which include the presence of a splenial symphysis, a...

Turtles from the Pliocene of Ahl al Oughlam (Casablanca, Morocco) and nearby Mio-Pliocene localities. The Late Pliocene locality Ahl al Oughlam (Casablanca, Morocco) yielded a fauna of cryptodiran testudinoid turtles, all of them related to extant African forms. Two terrestrial and one freshwater species are recognized. First, a new small species o...

Background: Secondary adaptation to aquatic life occurred independently in several amniote lineages, including reptiles during the Mesozoic and mammals during the Cenozoic. These evolutionary shifts to aquatic environments imply major morphological modifications, especially of the feeding apparatus. Mesozoic (250-65 Myr) marine reptiles, such as i...

The known European record of the Gondwanan group Podocnemididae begins in the EarlyEocene. Neochelys underwent a rapid diversification and was an abundant and diverse rep-resentative of this group during the Eocene of Europe from the Early Ypresian to at least theBartonian. However, several of its species are poorly known, and the phylogenetic rela...

A new species of the littoral cheloniid turtle Euclastes, E. acutirostris, is proposed, on the basis of a skull from the Palaeocene Phosphates of Morocco, the first turtle record from the Sidi Chennane area. It is estimated to be Danian-Thanetian in age, possibly younger than the previous Danian Moroccan specimens of Euclastes. It differs from the...

Abundant remains of turtles have been found in the fluviatile deposits of the Sperrgebiet, western border of the Namib Desert, South-Western Namibia, and particularly in the localities Elisabethfeld and Langental, lower Miocene, already mentioned by Stromer (1926) for the presence of Chelonians. The turtles are continental, mostly terrestrial, and...

During field work made by the museum " F. Eusebio" in the maris of Tortonian age outcropping in the bed of the Tanaro river, near Alba, a rich material of fish articulated skeletons was collected. Additionally, the skeleton of a marine turtle, sorne echinoderms and molluscs were also found. The study of the nannoplankton has made possible a precise...

The work represents the second part of the study pertaining to the definition of the genus Eurotestudo. The first part (Ann. Pal. 2006, 92 (3)) concentrated on the introduction to the subject and to the reporting of the morphological data, on which the definition is based. In this second part, results from the cladistic analysis are presented. All...

The new genus is created to include the species of the hermanni group, which is within Testudo s.l., a Palearctic genus, consequently separated from both Testudo s.s. and Agrionemys. A preliminary cladistic analysis of the osteological characters, including fossil species, demonstrated the splitting of the three lineages, probably since the Oligoce...

The Lower Cretaceous of Laos produced remains of freshwater cryptodiran turtles including some elements of aff. Xinjiangchelys and of Trionychoidea: Trionychidae, Carettochelyidae and beautiful specimens of a new species of Shachemys. The latter is defined, compared and placed in the family Adocidae. The family is reconsidered and the subfamily Sha...

Exceptional fossilization of large tetrapod swimming traces occurs in the Cerin Lagerstätte (Jura Mountains, France). These trackways are imprinted in Jurassic (Late Kimmeridgian) lagoonal fine-grained limestones and are attributed to giant turtles, which swam with a simultaneous movement of their forelimbs like the modern ones. These turtles swam...

Constituted of isolated fragments with a smooth decoration, the turtle material from Silveirinha is examined in order to define its sure belonging to Neochelys, by comparison with other smooth turtles which may be present during the Palaeogene of Europe (freshwater Testudinidae, Erymnochelyinae, Bothremydidae). The elements are compared with the al...

The Paleocene-Eocene mammalian faunal turnover included the first appearance in northern regions of Eurasia and America of artiodactyls, perissodactyls, primates and hyaenodontids. An origin of these groups in Asia seems very probable (with the exception of hyaenodontids, of possible African origin). Dispersal of these groups is highly contentious,...

‘Thoracosaurus’ cherifiensis Lavocat, 1955, a longirostrine from the late Lower Cretaceous of Morocco and Algeria, is attributed to Elosuchus, n. g., with another species, E. felixi n. sp., from In Abangarit (Niger), of the same age. Stolokrosuchus from the Lower Cretaceous of Niger is also referred to the new family Elosuchidae. Synapomorphies and...

A Neogene turtle from Brasil is described. It represents the first find of a new species close to the extant Podocnemis sextuberculata. Both species constitute a new clade in the genus.
