THE structure and relationships of the genus of fossil turtles known as Protostega are being gradually determined. Important additions to our knowledge regarding it have been made recently by Dr. E. C. Case I and Mr. G. R. Wieland.2 The former describes and figures in an excellent way the plastron, the skull, the shoulder girdle, and the limbs; and discusses at length the relationships to the other Testudines. Mr. Wieland supplies needed information regarding the ribs and the existence of… 
IX .-ON THE GROUP OF FOSSIL TURTLES KNOWN AS THE AMPHICHELYDIA ; WITH REMARKS ON THE ORIGIN AND RELATIONSHIPS OF THE SUBORDERS , SUPERFAMILIES , AND FAMILIES OF TESTUDINES
  • Biology
  • 2004
The group of turtles called the Amphichelydia was established by Mr. R. Lydekker in the year I889 and made to include, as the author states, a number of generalized later, Mesozoic forms which may be
Gross morphology and microstructure of type locality ossicles of Psephophorus polygonus Meyer, 1847 (Testudines, Dermochelyidae)
TLDR
P. polygonus was as cosmopolitan as extant Dermochelys and had a broadly similar ecology, with a possible difference concerning the dive depth, and the taxonomy of some of the Psephophorus-like species was preliminarily re-evaluate.
The early composition and evolution of the turtle shell (Reptilia, Testudinata)
The shell of the oldest true turtle (Testudinata) branch (Proterochersidae) from the Late Triassic (Norian) of Poland and Germany was built in its anterior and posterior part from an osteodermal
Morphogenetic and constructional differences of the carapace of aquatic and terrestrial turtles and their evolutionary significance
TLDR
Differences in the structure of the bony shell in aquatic and terrestrial turtles were shown to be associated with varying degrees of development of epidermal derivatives, namely, the thickness of the scutes and the depth of horny furrows.
The endoskeletal origin of the turtle carapace
TLDR
This work examines turtle embryos and finds that the costal and neural plates develop not within the dermis, but within deeper connective tissue where the rib and intercostal muscle anlagen develop.
THE ORIGIN AND EARLY EVOLUTION OF TURTLES
TLDR
A critical reexamination of turtle relationships continues to support a sister-group relationship of turtles with a clade of marine reptiles, Sauropterygia, within crown-group Diapsida (Sauria), and an aquatic origin of turtles is suggested.

Morphology and development of additional bony elements in the genus Brachycephalus (Anura: Brachycephalidae)
TLDR
The large additional elements associated with the skull (parotic plate) and vertebrae (vertebral and paravertebral plates) all comprise intramembranous bone, similar to that of the frontoparietal or nasal bones of the skull of most of frogs.
Fossil European Sea Turtles: A Historical Perspective
This chapter presents a historic perspective on the study of marine turtles from the Cretaceous-Tertiary strata of Europe from the Sixteenth Century to the Present Day. It details the historic
The integumentary skeleton of tetrapods: origin, evolution, and development
TLDR
Data support the notion that all osteoderms are derivatives of a neural crest‐derived osteogenic cell population and share a deep homology associated with the skeletogenic competence of the dermis, and that skeletogenesis is comparable with the formation of elasmoid scales.
