Abstract. Cardichelyon rogerwoodi is an enigmatic fossil turtle from the late Paleocene to early Eocene of North America. Previous analyses suggested affiliation with Testudinoidea, in particular the big-headed turtle Platysternon megacephalum, based on the presence of multiple musk-duct foramina and a large head. We here highlight previously undocumented characteristics for this turtle, notably the presence of short costiform processes, a rib-like axillary process, and a posterior plastral…

Geometric morphometrics and anatomical network analyses reveal ecospace partitioning among geoemydid turtles from the Uinta Formation, Utah
TLDR
The anatomical network analysis suggests that the carapace of B. pusilla distributed stress forces in a manner more similar to emydids than to derived testudinoids (Testudinidae and Emydidae), including Echmatemys species, changes the understanding of the ecology of the species and sheds light onto how geoemydid turtles of the Uinta Formation may have partitioned the available ecospace.
A nomenclature for fossil and living turtles using phylogenetically defined clade names
TLDR
This work converts the vast majority of previously defined clade names for extinct and extant turtles into this new nomenclatural framework, and establishes 113 clade Names, of which 79 had already received phylogenetic definitions and 34 are new.
Disentangling the correlated evolution of body size, life history, and ontogeny in miniaturized chelydroid turtles
TLDR
The analyses corroborated thatminiaturization in the Chelydroidea clade is underlain by a dampening of the ancestral growth trajectory and revealed an alternative miniaturization mode wherein exceptionally large hatchlings grow minimally and thus attain diminutive adult sizes.

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 Pan-Kinosternoidea
TLDR
Turtles of the total clade Pan-Kinosternoidea have a relatively poor fossil record that extends back to the Late Cretaceous, and a taxonomic review of the group concludes that of 42 named taxa, 27 are nomina valida, including two species of the controversial taxon Planetochelys.

TLDR
Turtles of the total clade Pan-Chelydridae have a relatively sparse fossil record that reaches back to the Late Cretaceous (Santonian) but spread along unclear routes to Asia and Europe during the Paleocene, only to go extinct on those continents by the end of the Pliocene.
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.

TURTLE DIVERSITY AND ABUNDANCE THROUGH THE LOWER EOCENE WILLWOOD FORMATION OF THE SOUTHERN BIGHORN BASIN
TLDR
It is thought that changes in habitat heterogeneity may be a better explanation and changes in the turtle fauna can best be understood by examining how change in climate, in combination with effects of local tectonic controls on floodplain development, affected the availability and preservation of diverse habitats.
