Four in One: Cryptic Diversity in Geoffroy’s Side-Necked Turtle Phrynops geoffroanus (Schweigger 1812) (Testudines: Pleurodira: Chelidae) in Brazil

Diversity, 2022
Turtles are one of the most threatened groups of vertebrates, with about 60% of species classified at some level of extinction risk. Compounding this extinction crisis are cryptic species and species complexes that are evaluated under a single species ...

Climate, Continental Breakup and Habitat Shape Global Diversification and Biogeography of Turtles (Testudines)

Journal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim Evaluate the relative contributions of palaeotemperature, palaeogeographic reconfiguration, and habitat heterogeneity to the diversification and biogeographic history of turtles (Order Testudines) from the Triassic to the present. Location and Time Period Global; Triassic–Recent.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Herpesviruses in Captive Chelonians in Europe Between 2016 and 2020

Frontiers in Veterinary Science, 2021
Herpesviruses are important pathogens in tortoises and turtles, yet little is known about the epidemiology of these viruses. We analyzed herpesviruses detected by PCR in samples from captive chelonians in Europe according to virus strain, host species ...

New remains of Titanochelon richardi (Testudines, Testudinidae) from the Upper Miocene of the Vallès‐Penedès Basin: taxonomic and phylogenetic implications

Papers in Palaeontology, Volume 11, Issue 6, November/December 2025.
Abstract The alpha‐taxonomy of continental giant tortoises (Testudinidae, Titanochelon) from the European Neogene is far from settled, which has implications for inferring their phylogenetic relationships. The diagnosis of the type species (Titanochelon bolivari) is dubious because it considered Titanochelon richardi as a junior subjective synonym ...

Mosaic morphology in Podocnemididae revealed by a new turtle from the Middle Miocene La Venta Biome, Colombia

Papers in Palaeontology, Volume 11, Issue 6, November/December 2025.
Abstract A new genus and species of podocnemidid turtle, Shakiremys colombiana, is described here from the Middle Miocene La Venta Biome, located in south‐central Colombia. The new taxon is represented by two specimens: one consisting of a complete skull and articulated shell, and the other of an articulated shell only.

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

American Museum Novitates, 2009
Abstract New cranial and postcranial material of the pleurodire family Bothremydidae, subtribe Bothremydina, from the Gulf Coastal Plain of North America, clarifies the distribution of the genera Bothremys and Chedighaii. New skull material from the Campanian Tar Heel Formation of North Carolina shows the presence of both Bothremys and Chedighaii ...

A new species of long-necked turtle (Pleurodira: Chelidae: Chelodina) from the late Miocene Alcoota Local Fauna, Northern Territory, Australia [PDF]

PeerJ, 2013
The new species Chelodina (Chelodina) murrayi is described from the late Miocene Alcoota Local Fauna of central Australia, in the Northern Territory. The new species is based on shell fragments and can be diagnosed by a ventrally reflexed anterior margin

A lower Pliocene Erymnochelyini turtle (Pleurodira, Podocnemididae) from the Democratic Republic of Congo

The Anatomical Record, 2022
AbstractThe presence of a pleurodiran turtle putatively attributable to Erymnochelys madagascariensis (i.e., the only representative of Erymnochelyini that is part of the current biodiversity) or to a closely related form was recognized, in the early 1990s, for the Lower Pliocene record of the Sinda‐Mohari region (Democratic Republic of Congo).
