ABSTRACT 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. Unconstrained and constrained cladistic analyses in addition to newly developed total-evidence Bayesian analysis were performed to explore large-scale turtle relationships and evolutionary trends. All the analyses show a similar resolution at the base of the tree, recovering several species of small… 
A reevaluation of the basal turtle Indochelys spatulata from the Early–Middle Jurassic (Toarcian–Aalenian) of India, with descriptions of new material
TLDR
The phylogenetic analysis affirms the placement of Indochelys spatulata as a basal mesochelydian, but cannot resolve its relationships relative to the roughly coeval Condorchelys antiqua and Kayentachelys aprix.
Cranial and post-cranial remains and phylogenetic relationships of the Gondwanan meiolaniform turtle Peligrochelys walshae from the Paleocene of Chubut, Argentina
TLDR
The updated phylogenetic analysis confirms that P. walshae is part of the clade Meiolaniformes, which spans from the Early Cretaceous until the Holocene and contains the giant, horned turtles (Meiolaniidae), and reinforces the previous hypothesis that the cl cluster is dominated by Gondwanan taxa, but also includes some Laurasian representatives.
Changes in the Diversity of Turtles (Testudinata) in South America from the Late Triassic to the Present
Abstract. Recent advances in the fossil record, anatomy, and evolutionary history of South American turtles allow a thorough analysis of their changes in diversity, and to identify several major
The making of calibration sausage exemplified by recalibrating the transcriptomic timetree of jawed vertebrates
TLDR
The present work reevaluate all thirty calibrations in detail, present the current state of knowledge on them with its various uncertainties, rerun the dating analysis, and conclude that calibration dates cannot be taken from published compendia or other secondary or tertiary sources without risking strong distortions to the results.
What do ossification sequences tell us about the origin of extant amphibians?
TLDR
Analysis of the cranial dataSupport for a monophyletic origin among lepospondyls, the current near-consensus, is a distant second; all other hypotheses are exceedingly unlikely according to the data.
Turtle remains from the Middle Jurassic Xintiangou Formation of Yunyang, Sichuan Basin, China
Abstract Three turtle shells from the Middle Jurassic Xintiangou Formation of Yunyang (Chongqing, China) are described and assigned to Xinjiangchelyidae (Testudines: Eucryptodira). This is the first
Comparative analysis of the shape and size of the middle ear cavity of turtles reveals no correlation with habitat ecology
TLDR
It is suggested that tympanic hearing in turtles evolved as a compromise between subaerial and underwater hearing, and that middle ear cavity shape may be controlled by factors unrelated to hearing, such as the spatial demands of surrounding cranial structures.

The Making of Calibration Sausage Exemplified by Recalibrating the Transcriptomic Timetree of Jawed Vertebrates
TLDR
This work reevaluate all 30 calibrations in detail, present the current state of knowledge on them with its various uncertainties, rerun the dating analysis, and conclude that calibration dates cannot be taken from published compendia or other secondary or tertiary sources without risking strong distortions to the results.

Evolution and palaeoecology of early turtles: a review based on recent discoveries in the Middle Jurassic
TLDR
It is demonstrated here that, by documenting yet unknown stages in the evolution of several morphological structures, these three species give stronger support to the model of an extended phylogenetic stem for turtles.
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.
A new platychelyid turtle (Pan-Pleurodira) from the Late Jurassic (Kimmeridgian) of Oaxaca, Mexico

TLDR
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.
A new turtle from the Palaeogene of Patagonia (Argentina) sheds new light on the diversity and evolution of the bizarre clade of horned turtles (Meiolaniidae, Testudinata)
TLDR
A new species of horned turtle from the Paleogene of Patagonia that sheds new light on the evolution and palaeobiogeographical history of the clade Meiolaniidae in Australasia and South America during the Cainozoic is presented.
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.

TLDR
Phylogenetic placement of fossils demonstrates that giant body size independently evolved in multiple continental mainland taxa and confirms recent results deduced from living taxa—giantism in Testudinidae is not linked to the insular effect.
The skeletal morphology of the solemydid turtle Naomichelys speciosa from the Early Cretaceous of Texas
TLDR
The full visibility of the parabasisphenoid complex in ventral view, the presence of an expanded symphyseal shelf, and the unusual ventromedial folding of the coronoid process are the primary characteristics that distinguish Naomichelys speciosa from the near-coeval European taxon Helochelydra nopcsai.
The cranial morphology of Kayentachelys, an Early Jurassic cryptodire, and the early history of turtles
TLDR
Kayentachelys reveals what a primitive cryptodire would be expected to look like: a combination of primitive and derived characters, with the fewer derived characters providing the best test of its relationships to other turtles.

TLDR
An updated cladistic analysis of turtles shows that C. antiqua and other fossil turtles are not crown turtles, but stem turtles, and that until the Middle to Upper Jurassic there were turtles without the modern jaw closure mechanism.
