Abstract Turtles (Testudinata) are the clade of amniotes characterized by a complete turtle shell. [] Key Result Sedimentological, anatomical, and histological data universally hint at terrestrial habitat preference among the earliest stem turtles, but a more mixed, though unambiguously continental signal is apparent further towards the crown.

Triassic turtles from Pangea: The legacy from South America
A Review of the Fossil Record of Nonbaenid Turtles of the Clade Paracryptodira
  • W. Joyce, J. Anquetin
  • Geography, Environmental Science
    Bulletin of the Peabody Museum of Natural History

Abstract The fossil record of nonbaenid paracryptodires ranges from the Late Jurassic (Kimmeridgian) to the Paleocene of North America and Europe only. Earlier remains may be present as early as…
A new phylogenetic hypothesis of turtles with implications for the timing and number of evolutionary transitions to marine lifestyles in the group
TLDR
A new phylogenetic hypothesis informed by high resolution computed tomographic data of living and fossil taxa is presented, indicating three independent evolutionary transitions to marine life in non‐pleurodiran turtles (plus an additional two‐three in pleurodires).
The ecomorphology of the shell of extant turtles and its applications for fossil turtles
TLDR
Although the shape of the shell of turtles indeed contains an ecological signal, it is overall too weak to uncover using shell shape in paleoecological studies, at least with the methods selected.
New Remains of Condorchelys antiqua (Testudinata) from the Early-Middle Jurassic of Patagonia: Anatomy, Phylogeny, and Paedomorphosis in the Early Evolution of Turtles
TLDR
New cranial and postcranial remains of the Early–Middle Jurassic turtle, Condorchelys antiqua, are described here in detail, providing new insights into the early evolution of turtles, corroborating that the Jurassic is a key period for turtle evolution.
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.
A Review of the Fossil Record of Old World Turtles of the Clade Pan-Trionychidae

Abstract Turtles of the clade Pan-Trionychidae have a rich fossil record in the Old World, ranging from the Early Cretaceous (Hauterivian) to the Holocene. The clade most probably originated in Asia…
The giant pliosaurid that wasn’t: revising the marine reptiles from the Kimmeridgian (Upper Jurassic) of Krzyżanowice, Poland
Marine reptiles from the Upper Jurassic of Central Europe are rare and often fragmentary, which hinders their precise taxonomic identification and their placement in a palaeobiogeographic context.…
Basal turtle material from the Lower Cretaceous of Yakutia (Russia) filling the gap in the Asian record
Chinlechelys from the Upper Triassic of New Mexico, USA, and the origin of turtles
TLDR
The morphology of Chinlechelys tenertesta supports the placement of Testudines outside of crown Sauria, as a taxon derived from pareiasaurs based on the morphology of the dorsal osteoderms and skull roof and reaffirm its unequivocal support for the composite model of costal bone formation in turtles.

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 sinemydid turtle from the Jehol Biota provides insights into the basal divergence of crown turtles
TLDR
The analysis indicates that sinemydids mostly share symplesiomorphies with sea turtles and their purported placement outside the crown-group of turtles is an artefact of previous datasets, so the best current phylogenetic estimate is therefore that Sinemydidae are part of the stem lineage of Cryptodira together with an array of other Jurassic to Cretaceous taxa.
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.
A Review of the Fossil Record of Turtles of the Clade Baenidae
TLDR
Baenids were warmadapted freshwater aquatic turtles that supported high levels of diversity at times through niche partitioning, particularly by adapting to a broad range of dietary preferences ranging from omnivorous to molluscivorous.
Reassessment of the phylogenetic interrelationships of basal turtles (Testudinata)
TLDR
Perhaps the most salient conclusion of the present study is the placement of Naomichelys speciosa as a basal member of a clade uniting meiolaniids, Mongolochelys efremovi and Otwayemys cunicularius.
A new stem turtle from the Middle Jurassic of Scotland: new insights into the evolution and palaeoecology of basal turtles
TLDR
A phylogenetic analysis places the new taxon within the stem group of Testudines (crown-group turtles) and suggests a sister-group relationship between E. waldmani and Heckerochelys romani from the Middle Jurassic of Russia.

TLDR
The ecology of fossil pan-carettochelyids appears similar to that of the extant C. insculpta, although more primitive representatives were likely less adapted to brackish water.

The shell bone histology of fossil and extant marine turtles revisited
TLDR
A review of previously published as well as unpublished data of shell microstructures of these groups and those of some of the earliest aquatic turtles from the Middle Jurassic show that bones are strongly influenced functionally as a result of life spent in an aquatic medium, whereas there are little to no characters of systematic value in the bones.

TLDR
The recently revived paleontological hypothesis that the Middle Permian Eunotosaurus africanus is an intermediate stem turtle is now robustly supported by numerous characters that were previously thought to be unique to turtles and that are now shown to have originated over the course of tens of millions of years unrelated to the origin of the turtle shell.
