Abstract The family Podocnemididae consists of 20 genera and 30 species considered here as valid and diagnosable by cranial characters. Three of these genera and eight species persist into the Recent fauna, barely reflecting the evolutionary diversity and distribution of the group. The family extends from the Late Cretaceous to the Recent and occurs in North and South America, Europe, Asia, and Africa. A phylogenetic analysis utilizes 31 podocnemidid taxa (30 named and one unnamed; a total of… 
The last marine pelomedusoids (Testudines: Pleurodira): a new species of Bairdemys and the paleoecology of Stereogenyina
TLDR
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.
A global phylogeny of Pelomedusoides turtles with new material of Neochelys franzeni Schleich, 1993 (Testudines, Podocnemididae) from the middle Eocene, Messel Pit, of Germany
TLDR
A revised diagnosis for the species is presented here, together with its inclusion in a global phylogenetic analysis of Pelomedusoides that shows that this species and the whole Neochelys spp.
A small podocnemidoid (Pleurodira, Pelomedusoides) from the Late Cretaceous of Brazil, and the innervation and carotid circulation of side‐necked turtles
Pleurodires are less diverse than cryptodires, together forming the two major lineages of crown turtles. Their fossil record, however, is rich. A particularly large number of fossil pleurodires, many
Revision of the Triassic European turtles Proterochersis and Murrhardtia (Reptilia, Testudinata, Proterochersidae), with the description of new taxa from Poland and Germany
TLDR
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 pelomedusoid turtles from the late Palaeocene Cerrejón Formation of Colombia and their implications for phylogeny and body size evolution
TLDR
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.
The Erymnochelys group of turtles (Pleurodira, Podocnemididae) in the Eocene of Europe: New taxa and paleobiogeographical implications
TLDR
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.
Anatomy of Rhinochelys pulchriceps (Protostegidae) and marine adaptation during the early evolution of chelonioids
TLDR
A phylogeny of turtles with increased chelonioid taxon sampling and revised postcranial characters is provided, recovering protostegids as stem-chelonioids, which imply a mid Early Cretaceous origin of total-group chelonIOids and an early Late Cret Jurassic age for crown-chelanioids.
New insights into the anatomy and systematic of ‘Papoulemys’ laurenti, a representative of Neochelys (Chelonii, Podocnemididae) from the early Eocene of the south of France
TLDR
A new diagnosis is proposed for ‘Papoulemys’ laurenti, reallocating the species to Neochelys, and the available information on this genus and on several of its representatives is expanded.
Valanginian occurrence of Pelomedusoides turtles in northern South America: revision of this hypothesis based on a new fossil remain
TLDR
A new fragmentary specimen from the Rosa Blanca Formation, represented by a right portion of the shell bridge, including the mesoplastron and most of peripherals 5 to 7, allows me to support its attribution as belonging to Pelomedusoides, a group to which the previously podocnemidoid material is also attributed here.
Sokatra, a New Side-Necked Turtle (Late Cretaceous, Madagascar) and the Diversification of the Main Groups of Pelomedusoides
TLDR
The deep phylogenetic roots of Sokatra indicates the presence of its lineage on Madagascar prior to the beginning of the Late Cretaceous.

EVOLUTION OF THE SIDE-NECKED TURTLES: THE FAMILIES BOTHREMYDIDAE, EURAXEMYDIDAE, AND ARARIPEMYDIDAE
TLDR
Current discoveries show that pleurodires had a more complex and extensive evolutionary history than had been realized, and previously unknown radiations, particularly in the near-shore marine realm, are revealed by taxa with diverse cranial morphology.
A new freshwater turtle (Reptilia, Pleurodira, Podocnemidae) from the upper Cretaceous (Maastrichtian) of Minas Gerais, Brazil
The fossil fauna of freshwater turtles from the Bauru Basin, south central Brazil, includes only podocnemids (Pleurodira, Pelomedusoides). A new genus and species, Cambaremys langertoni n. gen., n.
Caninemys, A New Side-Necked Turtle (Pelomedusoides: Podocnemididae) from The Miocene of Brazil
TLDR
A new genus and species of podocnemidid pleurodire, Caninemys tridentata, is described on the basis of a skull collected by L.I. Price in 1962 from the late Miocene of Acre, Brazil, which has previously been identified as the shell-based genus Stupendemys, but there are no associations supporting this assignment.
The oldest pre-Podocnemidid turtle (Chelonii, Pleurodira), from the early Cretaceous, Ceará state, Brasil, and its environment
TLDR
The turtle fauna in Chapada do Araripe includes four freshwater Pelomedusoides, samples of the ancient northern Gondwana fauna, as well as a cryptodiran turtle, possibly a littoral form belonging to a more cosmopolitan group, which dates between the late Aptian fauna of Gadoufaoua (Niger) and the late Albian-early Cenomania fauna from the Sahara.
ARE EXTANT PODOCNEMIDID TURTLES RELICTS OF A WIDESPREAD CRETACEOUS ANCESTOR?
TLDR
This new phylogenetic hypothesis places B. elegans as a basal form of Podocnemididae and is used to found a new biogeographic model for the Pelomedusoides, which allows the association of vicariance events of Gondwana fragmentation during the Cretaceous with the isolation of pelomedusoid lineages.
PHYLOGENETIC RELATIONSHIPS OF THE BAURU GROUP TURTLES (LATE CRETACEOUS OF SOUTH-CENTRAL BRAZIL)
TLDR
The resulting hypothesis of relationships places the specimen known as FR-4922 and Brasilemys josai among Pelomedusoides basal to Podocnemoidea, and a sister group relationship between Peltocephalus dumerilianus and Erymnochelys madagascariensis is proposed.
Skeletal morphology and relationships of the early Cretaceous side-necked turtle, Araripemys barretoi (Testudines: Pelomedusoides: Araripemydidae), from the Santana Formation of Brazil
TLDR
Examination of 35 skeletal characters in six living and nine extinct taxa suggest that there are four distinct clades in the Pelomedusidae (sensu lato).

A phylogeny for side-necked turtles (Chelonia: Pleurodira) based on mitochondrial and nuclear gene sequence variation
TLDR
The molecular data support the currently accepted arrangement for pelomedusid genera, that is, a sister relationship between the African Pelusios and Pelomedusa and a clade comprising the South American Peltocephalus and Podocnemis with the Madagascan Erymnochelys .
