Synopsis. The body plan of turtles is unique among tetrapods in the presence ofthe shell. The structure of the carapace involves a unique relationship between the axial and the appendicular skeletons. A common developmental mechanism, an epithelial-mesenchymal interaction, has been identified in the early stages of carapace development by means of basic histological and immunofluorescence techniques. By analogy to other structures ini? tiated by epithelial-mesenchymal interactions, it is… 

Origin of the Turtle Body Plan: The Folding Theory to Illustrate Turtle-Specific Developmental Repatterning

This developmental sequence of the modern turtles aligns with a stepwise evolutionary process in the group, which is supported by the anatomy of a recently discovered fossil species, Odontochelys.

Body plan of turtles: an anatomical, developmental and evolutionary perspective

Comparative developmental data allow us to hypothesize the gradual evolution of turtles, which is consistent with the recent finding of a transitional fossil animal, Odontochelys, which did not have the carapace but already possessed the plastron.

Evolutionary developmental perspective for the origin of turtles: the folding theory for the shell based on the developmental nature of the carapacial ridge

The turtle body plan can be explained with knowledge of vertebrate anatomy and developmental biology, consistent with the evolutionary origin of the turtle suggested by the recently discovered fossil species, Odontochelys.

Development of the carapacial ridge: implications for the evolution of genetic networks in turtle shell development

Molecular evidence is shown supporting a dermomyotomal identity for the mesenchyme of the turtle carapacial ridge and establishes a new role for this mesodermal compartment and highlights the importance of changes in genetic regulation in the evolution of morphology.

The Turtle Evolution: A Conundrum in Vertebrate Evo-Devo

The stepwise, not necessarily saltatory, evolution of turtles is hypothesized, consistent with the recent finding of a transitional fossil animal, Odontochelys, that did not have the carapace but already possessed the plastron.

Evolution of the Turtle Body Plan by the Folding and Creation of New Muscle Connections

This work proposes that the evolutionary origin of the turtle body plan results from heterotopy based on folding and novel connectivities, and suggests that some limb muscles establish new turtle-specific attachments associated with carapace formation.

On the carapacial ridge in turtle embryos: its developmental origin, function and the chelonian body plan

It is concluded that the CR is a true embryonic novelty among amniotes and, because of the specific expression of regulatory genes, it functions in the marginal growth of the carapacial primordium, thereby inducing the fan-shaped arrangement of the ribs.

Morphogenesis of the turtle shell: the development of a novel structure in tetrapod evolution

An anatomical investigations into plastron and carapace formation in the red‐eared slider, Trachemys scripta, and the snapping turtle, Chelydra serpentina suggest that the rib is organizing dermal ossification by secreting paracrine factors.

Turtle–chicken chimera: An experimental approach to understanding evolutionary innovation in the turtle

It is concluded that chicken and P. sinensis share the developmental programs necessary for the early differentiation of somites and that turtle-specific traits in muscle patterning arise mainly through a cell‐autonomous developmental process in the somites per se, however, the mechanism for turtle‐specific cartilage patterning, including that of the ribs, is not supported by the chicken embryonic environment.

On the Development of the Turtle Scute Pattern and the Origins of its Variation

A novel computational approach to elucidating carapacial scute development using a combination of two mechanistically different reaction-diffusion systems together with growth reproduces scute formation in the carapace is presented.

Experiments seem to establish that the radial muscles remain haploneurous, retaining their primitive connection with the nerve belonging to that myotome from which they have been developed, which supports the lateral fold theory of the origin of the paired fins.

Historical Analysis of Theories of Chelonian Relationship

Proposed chelonian hierarchies are described and compared from this point of view based on examinations of many biotic classifications and organizing systems, and much of the following discussion has been inspired by their analysis.

It was demonstrated that both somitic and somatopleural mesoderm are regionalized as early as 2 days of incubation, prior to somitic segmentation, with respect to their ability to give rise to the skeletal elements of the girdles.

Rib development in chick embryos analyzed by means of tantalum foil blocks.

Rib development in chick embryos, with special emphasis on the origin of ribforming cells, has been analyzed by inserting tantalum foil blocks parallel to certain somites of the prospective rib-forming level and it was concluded that the original somatic mesoderm does not participate in formation of vertebral rib components.
