A new Late Cretaceous turtle, Angolachelys mbaxi gen. et sp. nov., from the Turonian (90 Mya) of Angola, represents the oldest eucryptodire from Africa. Phylogenetic analysis recovers Angolachelys mbaxi as the sister taxon of Sandownia harrisi from the Aptian of Isle of Wight, England. An unnamed turtle from the Albian Glen Rose Formation of Texas (USA) and the Kimmeridgian turtle Solnhofia parsonsi (Germany), are successively more distant sister taxa. Bootstrap analysis suggests those four… 

Morphology and Relationships of Brachyopsemys tingitana gen. et sp. nov. from the Early Paleocene of Morocco and Recognition of the New Eucryptodiran Turtle Family: Sandownidae

The first cryptodiran turtle with a pitted palate, Brachyopsemys tingitana gen. et sp. nov., is described on the basis of skulls and a lower jaw from the early Paleocene (Danian) of the Ouled Abdoun

The North African Mosasaur Globidens phosphaticus from the Maastrichtian of Angola

New mosasaur fossils from Maastrichtian beds at Bentiaba, Angola, representing elements of the skull and postcranial axial skeleton from two individuals of the durophagous genus Globidens, are

The first South American sandownid turtle from the Lower Cretaceous of Colombia

TLDR
The morphology of L. cipadi indicates that sandownids were not open marine turtles, but instead littoral to shallow marine durophagous dwellers, which supports once again the monophyly of Sandownidae.

A new durophagous stem cheloniid turtle from the lower Paleocene of Cabinda, Angola

A new stem cheloniid turtle, Cabindachelys landanensis, gen. et sp. nov., is represented by a nearly complete skull and partial hyoid collected in lower Paleocene shallow marine deposits, equivalent

A toothed turtle from the Late Jurassic of China and the global biogeographic history of turtles

TLDR
A revision of the global distribution of fossil and recent turtle reveals that the three primary lineages of derived, aquatic turtles, including the crown, Paracryptodira, Pan-Pleurodira, and Pan-Cryptodira can be traced back to the Middle Jurassic of Euramerica, Gondwana, and Asia, respectively, which resulted from the primary break up of Pangaea at that time.

A Review of the Fossil Record of Turtles of the Clade Thalassochelydia

TLDR
Thalassochelydians are universally found in near-shore marine sediments and show adaptations to aquatic habitats, but isotopic evidence hints at a broad spectrum of specializations ranging from freshwater aquatic to fully marine.

First Record of Eucryptodiran Turtles from the Early Cretaceous (Valanginian), at the Northernmost Part of South America

  • E. Cadena
  • Environmental Science, Geography
  • 2011
TLDR
These fossils represent the oldest record of eucryptodiran turtles for the northernmost part of South America and resemble marine turtles in morphology and histology particularly to Protostegidae clade.

Turonian marine amniotes from the Bohemian Cretaceous Basin, Czech Republic

Abstract Despite being known for over 155 years, the Late Cretaceous marine amniotes of the Bohemian Cretaceous Basin in the Czech Republic have received little recent attention. These fossils are

The last surviving Thalassochelydia—A new turtle cranium from the Early Cretaceous of the Purbeck Group (Dorset, UK)

Background. The mostly Berriasian (Early Cretaceous) Purbeck Group of southern England has produced a rich turtle fauna dominated by the freshwater paracryptodires Pleurosternon bullockii and

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

TLDR
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.

THE OCCURRENCE AND GEOLOGICAL SETTING OF CRETACEOUS DINOSAURS, MOSASAURS, PLESIOSAURS, AND TURTLES FROM ANGOLA

Vertebrate-bearing fossiliferous outcrops of Cretaceous age in sub-Saharan Africa are rare because of younger superficial deposits, vegetation cover, and the widespread occurrence of Precambrian

Phylogenetic Relationships of Mesozoic Turtles

TLDR
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.

Acleistochelys, a New Side-Necked Turtle (Pelomedusoides: Bothremydidae) from the Paleocene of Mali

Abstract The Paleocene Teberemt Formation south of the Adrar des Iforas Mountains, between Saguirilidad and In Fargas, Mali, yielded a nearly complete skull of a new genus and species of side-necked

A REASSESSMENT OF THE REFERRAL OF SEA TURTLE SKULLS TO THE GENUS OSTEOPYGIS (LATE CRETACEOUS, NEW JERSEY, USA)

TLDR
Multiple lines of evidence combine to support the hypothesis that sea turtle cranial material is not attributable to Osteopygis, and reconciles morphological trends within stem cheloniids.

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.

Soinhofia parsonsi , a New Cryptodiran Turtle from the Late Jurassic of Europe

TLDR
Solnhofia parsonsi is a new genus and species of turtle based on skull material from the Late Jurassic of Germany and Switzerland that possesses the shared derived characters diagnostic of the Cryptodira and within the cryptodira of a group I have termed the Eucryptodira.
