ABSTRACT Graptemys kerneri, n. sp., from the Suwannee River drainage of north-central Florida, represents the most southeastern occurrence of the genus. This species is morphologically and geographically most similar to the extant Barbour's map turtle, Graptemys barbouri. G. kerneri exhibits sexual dimorphism similar to extant G. barbouri, G. ernsti, G. pulchra, and G. gibbonsi, with females being megacephalic and attaining a much larger size than males. The new species possesses a very wide… 
Hybridization of Two Megacephalic Map Turtles (Testudines: Emydidae: Graptemys) in the Choctawhatchee River Drainage of Alabama and Florida
TLDR
The results provide a first counter-example to the pattern of drainage-specific endemism in megacephalic Graptemys and indicate that the invasion of the Choctawhatchee system by these species likely predates any potential human-mediated introduction.
A new slider turtle (Testudines: Emydidae: Deirochelyinae: Trachemys) from the late Hemphillian (late Miocene/early Pliocene) of eastern Tennessee and the evolution of the deirochelyines
TLDR
The new taxon, Trachemys haugrudi, is described, and currently represents the most thoroughly described fossil emydid species known, and a phylogenetic analysis is performed that includes the new fossil species, along with numerous other modern and fossil deirochelyine species, representing the first phylogenetics analysis published that includes several fossil deIROchelyines.
Turtles of the Early Pleistocene Santa Fe River 1B Locality
The early Pleistocene (ca. 2.588–1.806 Ma) Santa Fe River 1B fossil site (SF1B) of Gilchrist County, Florida has yielded turtle fossils representing nine genera and at least 10 species. Of these, at
A Review of the Fossil Record of North American Turtles of the Clade Pan-Testudinoidea
Abstract Turtles of the clade Pan-Testudinoidea have a rich fossil record in North America, including the Caribbean, ranging from the late Paleocene to the Holocene. All earlier reports cannot be
LATE CRETACEOUS DINOSAUR BIOGEOGRAPHY AND ENDEMISM IN THE WESTERN INTERIOR BASIN, NORTH AMERICA: A CRITICAL RE-EVALUATION
North-south provinciality among Campanian and/or Maastrichtian vertebrates, especially dinosaurs, in the Western Interior basin of North America (specifically, between West Texas and southern
The Fossil Record of the Diamond-backed Terrapin, Malaclemys terrapin (Testudines: Emydidae)
TLDR
These new fossil records provide evidence that Malaclemys was distributed throughout the southeastern United States during the Late Pleistocene, and the features of scute sulci and the presence of annuli scars on most specimens are identified.
Turtle Hotspots: An Analysis of the Occurrence of Tortoises and Freshwater Turtles in Biodiversity Hotspots, High-Biodiversity Wilderness Areas, and Turtle Priority Areas
Abstract We analyzed the taxon richness and endemism of tortoises and freshwater turtles in the world’s premier biodiversity conservation priority areas and countries with greatest turtle richness.

A Revision of Plesiobaena (Testudines: Baenidae) and an Assessment of Baenid Ecology Across the K/T Boundary
TLDR
The phylogenetic analysis clearly reveals that Plesiobaena in the traditional sense is a paraphyletic assemblage relative to the clade formed by Gamerabaena sonsalla and Palatobaena spp.
EVOLUTION OF BODY SIZE IN THE MAP TURTLES AND SAWBACKS (EMYDIDAE: DEIROCHELYINAE: GRAPTEMYS)
TLDR
The hypothesis that character displacement of body size in females was important in the radiation of map turtle and sawback species is argued against and a functional relationship whereby degree of molluscivory in females covaries with body size is suggested.
FIRST FOSSIL RECORD FOR THE DIAMONDBACK TERRAPIN , MALACLEMYS TERRAPIN ( EMYDIDAE ) , AND COMMENTS ON THE FOSSIL RECORD OF CHRYSEMYS NELSONI ( EMYDIDAE )
A nuchal bone and a first left costal bone from two different individuals represent the first fossil record for the diamondback terrapin, Malaclemys terrapin. The bones are from a Pleistocene deposit

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.
The head and neck muscles associated with feeding in Sphenodon (Reptilia: Lepidosauria: Rhynchocephalia)
TLDR
An up-to-date consensus view of osteology and musculature in Sphenodon that is relevant to feeding is provided and the complex muscle arrangement is displayed using a range of different imaging techniques and a variety of different angles.
Evolution of the Emydine Turtles Graptemys and Malaclemys (Reptilia, Testudines, Emydidae)
TLDR
It is suggested that the brackish water adapted turtle Malaclemys terrapin gave rise directly to many or perhaps even most of the different species of the fresh water genus Graptemys.

MOLECULAR SYSTEMATICS OF THE GENUS CLEMMYS AND THE INTERGENERIC RELATIONSHIPS OF EMYDID TURTLES
TLDR
Phylogenetic analysis identifies two major clades and corroborates previous morphological assignments of genera to the subfamilies Deirochelyinae and Emydinae, and identifies the sister taxon to all other genera in the subfamily.
