Abstract Although pleurodires have been considered significantly less diverse than their sister group, the cryptodires, current discoveries show that pleurodires had a more complex and extensive evolutionary history than had been realized. Previously unknown radiations, particularly in the near-shore marine realm, are revealed by taxa with diverse cranial morphology, indicating many different feeding and sensory strategies. The pleurodire group that is changed the most by the new discoveries is… 

Evolution of the Side-Necked Turtles: The Family Podocnemididae

The family Podocnemididae is reconfirmed as monophyletic, using the unique possession of a cavum pterygoidei formed by the basisphenoid, pterygoid, prootic, and quadrate, and the resulting consensus of nine equally parsimonious cladograms is the basis for a new classification of the family.

A new turtle taxon (Podocnemidoidea, Bothremydidae) reveals the oldest known dispersal event of the crown Pleurodira from Gondwana to Laurasia

The discovery of a new turtle from the southern Laurasian Cenomanian site of Algora in Spain shows that the first dispersals of Pleurodira from Gondwana to Laurasia occurred much earlier than previously thought.

A new pelomedusoid turtle, Sahonachelys mailakavava, from the Late Cretaceous of Madagascar provides evidence for convergent evolution of specialized suction feeding among pleurodires

A functional assessment suggests that Sahonachelys mailakavava was a specialized suction feeder that preyed upon small-bodied invertebrates and vertebrates that highlights the distinct evolutionary pathways taken by Madagascan vertebrates.

Revision of the Triassic European turtles Proterochersis and Murrhardtia (Reptilia, Testudinata, Proterochersidae), with the description of new taxa from Poland and Germany

New discovered plesiomorphic aspects of the anatomy of these three species included in the phylogenetic analysis demonstrate that they are not only the oldest, but are also the most basal fully shelled turtles.

New Material of North American Side-Necked Turtles (Pleurodira: Bothremydidae)

New cranial and postcranial material from the Gulf Coastal Plain of North America and the Campanian Tar Heel Formation of North Carolina shows the presence of both Bothremys and Chedighaii, based on a maxilla and lower jaw.

A small podocnemidoid (Pleurodira, Pelomedusoides) from the Late Cretaceous of Brazil, and the innervation and carotid circulation of side‐necked turtles

The neuroanatomy of side‐necked turtles with the aid of micro‐computed tomography of specimens of the main pleurodiran lineages is explored, light is shed on the different carotid circulation patterns in pleurodires, and new phylogenetic characters are proposed to describe the Neuroanatomical variation of the group.

The Erymnochelys group of turtles (Pleurodira, Podocnemididae) in the Eocene of Europe: New taxa and paleobiogeographical implications

Eocenochelus is a taxon with a wide distribution in Europe during the Eocene and is relatively diverse, including the continental Neochelys, the only other podocnemidid genus so far recognized in the European Paleogene record.

The last marine pelomedusoids (Testudines: Pleurodira): a new species of Bairdemys and the paleoecology of Stereogenyina

A new Stereogenyina species is described, based on an almost complete skull from the middle Miocene Capadare Formation, of Venezuela, and it is proposed that stereogenyins were a marine radiation of podocnemidid turtles, as corroborated by previous studies of fossil eggs and limb morphology.

Sokatra, a New Side-Necked Turtle (Late Cretaceous, Madagascar) and the Diversification of the Main Groups of Pelomedusoides

The deep phylogenetic roots of Sokatra indicates the presence of its lineage on Madagascar prior to the beginning of the Late Cretaceous.

New pelomedusoid turtles from the late Palaeocene Cerrejón Formation of Colombia and their implications for phylogeny and body size evolution

Results from the Cerrejón turtles demonstrate that at least two major subclades of Podocnemidae were already in place in the neotropics by the Early Cenozoic and suggests that climatic variation is not the primary driver of major body size changes.

Examination of 35 skeletal characters in six living and nine extinct taxa suggest that there are four distinct clades in the Pelomedusidae (sensu lato).

SANDOWNIA HARRISI, A HIGHLY DERIVED TRIONYCHOID TURTLE (TESTUDINES: CRYPTODIRA) FROM THE EARLY CRETACEOUS OF THE ISLE OF WIGHT, ENGLAND

This specimen is one of the oldest known cryptodiran turtles that nests within the living families (the Polycryptodira) and suggests that the deep divergences among theliving families of the Cryptodira occurred more than 110 million years ago.

Cearachelys, a New Side-Necked Turtle (Pelomedusoides: Bothremydidae) from the Early Cretaceous of Brazil

The early Cretaceous Santana Formation exposed on the Chapada do Araripe in Ceará State, northeastern Brazil, has yielded remains of a side-necked turtle, Cearachelys placidoi, new genus and species, which is best resolved as the sister group of Bothremydidae.

Foxemys, a new side-necked turtle (Bothremydidae, Pelomedusoides) from the late Cretaceous of France. American Museum novitates ; no. 3251

A PAUP analysis of 23 characters and four bothremydid taxa has resulted in one cladogram showing Foxemys as the sister taxon to Taphrosphys, Bothremys, and Rosasia, however, only one character, an open incisura columellae auris, is the basis for this relationship, and it is considered to be weakly supported.

The phylogenetic hypothesis proposed supports a sister-group relationship between Yaminuechelys and Hydromedusa, a monophyletic group supported by cranial and postcranial derived characters, and differentiated in Patagonia at least as early as the upper Cretaceous.

The oldest record of Erymnochelys or a taxon very similar to it is indicated, the persistence of a Mesozoic element in the extant Malagasy turtle fauna is indicated and the possible bothremydid jaw suggests a more cosmopolitan element now extinct.
