Pelomedusoides comprises five moderate-sized extant genera with an entirely Southern Hemisphere distribution, but the fossil record of these turtles reveals a great diversity of extinct taxa, documents several instances of gigantism, and indicates a complex palaeobiogeographical history for the clade. Here, we report new pelomedusoid turtle fossils from the late Palaeocene Cerrejón Formation of Colombia. The most complete of these is represented by a large skull (condylobasal length = 16 cm… 

New turtle remains from the Late Cretaceous of Monte Alto-SP, Brazil, including cranial osteology, neuroanatomy and phylogenetic position of a new taxon

A high diversity of land vertebrates is known from the Late Cretaceous deposits of the Bauru Basin, Brazil, including at least five turtle taxa, all belonging to the clade Podocnemidoidae. Some of

Valanginian occurrence of Pelomedusoides turtles in northern South America: revision of this hypothesis based on a new fossil remain

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.

A global phylogeny of Pelomedusoides turtles with new material of Neochelys franzeni Schleich, 1993 (Testudines, Podocnemididae) from the middle Eocene, Messel Pit, of Germany

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.

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.

The largest Cretaceous podocnemidoid turtle (Pleurodira) revealed by an isolated plate from the Bauru Basin, south-central Brazil

Abstract The Bauru Basin (south-central Brazil) fossils have largely contributed to understand the faunal composition of South American Cretaceous. Among those, several turtle specimens were

Early to Middle Miocene Turtles from the Northernmost Tip of South America: Giant Testudinids, Chelids, and Podocnemidids from the Castilletes Formation, Colombia

Abstract. Here we describe the northernmost South American record of fossil turtles from the late early Miocene to early middle Miocene of the Castilletes Formation, on the Alta Guajira Peninsula,

A new podocnemidid (Pleurodira: Pelomedusoides) from the Eocene of north-western Argentina, with comments on its evolutionary relationships and palaeoenvironmental settings

We report a new small podocnemidid, Gestemys powelli gen. et sp. nov., based on one nearly complete skull, lower jaw, two shells, and remains of the appendicular skeleton belonging to two specimens

First report of a bothremydid turtle, Sindhochelys ragei n. gen., n. sp., from the early Paleocene of Pakistan, systematic and palaeobiogeographic implications

ABSTRACT We report the discovery of remains of a large chelonian from the base of the early Paleocene Khadro Formation exposed in the Ranikot Fort area (Ranikot Group, Sindh Province, Southern

A new blunt-snouted dyrosaurid, Anthracosuchus balrogus gen. et sp. nov. (Crocodylomorpha, Mesoeucrocodylia), from the Palaeocene of Colombia

A new exceptionally brevirostrine dyrosaurid is described from the middle Palaeocene Cerrejón Formation, northeastern Colombia, based on four partial skulls and associated postcrania, which indicates a deviation from surface-based predation to sub-surface predation as in modern Gavialis.




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.


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.

Phylogenetic Relationships of Mesozoic Turtles

This revised topology has important implications for the evolution of several character complexes, because it implies that the common ancestor of all living turtles must have had a partially braced brain case and a primitive trochlear mechanism.

The oldest pre-Podocnemidid turtle (Chelonii, Pleurodira), from the early Cretaceous, Ceará state, Brasil, and its environment

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.

Caninemys, A New Side-Necked Turtle (Pelomedusoides: Podocnemididae) from The Miocene of Brazil

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.

A New Baenid Turtle from the Upper Cretaceous (Maastrichtian) Hell Creek Formation of North Dakota and a Preliminary Taxonomic Review of Cretaceous Baenidae

A fragmentary skull from the Hell Creek Formation of southwestern North Dakota represents a new taxon of baenid turtle named herein Gamerabaena sonsalla, which has several morphological features that are intermediate between Plesiobaena antiqua and the morphologically disparate Palatobaena spp.

Impact of increased character sampling on the phylogeny of Cetartiodactyla (Mammalia): combined analysis including fossils

The phylogenetic position of Cetacea (whales, dolphins and porpoises) is an important exemplar problem for combined data parsimony analyses because the clade is ancient and includes many well‐known

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 Small Short-Snouted Dyrosaurid (Crocodylomorpha, Mesoeucrocodylia) from the Paleocene of Northeastern Colombia

An African origin of Dyrosauridae with dispersals to the New World by the Late Cretaceous or earliest Paleocene is supported and a radiation of dyrosaurid crocodyliforms, possibly following the K-P boundary, in tropical South America is suggested.


The discovery of Portezueloemys patagonica new genus and species confirms the coexistence in northwestern Patagonia of a north gondwanan component (Pelomedusoides) and a south gondwana element (Chelidae) during the Turonian-Coniacian.
