The scute mosaic (pholidosis) of the turtle shell is a complex correlated system of the modular type. Horny scutes are separate morphological elements partially closely connected with each other and partially relatively autonomous in development. The last feature causes high variability of scutes in the shape, size, rate and direction of growth, and provides the basis of transformation of the entire mosaic. In the evolution of turtles, the horny shell changed towards a decrease in the number of… 

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.

The macroevolutionary and developmental evolution of the turtle carapacial scutes

It is argued that turtles with complete loss of scutes follow clade-specific macroevolutionary regimes, which are distinct from the majority of other turtles, and a parallel is drawn between the variation of scute patterns on the carapace of turtles and the scale patterns in the pileus region of squamates.

Supernumerary scutes verify a segment‐dependent model of the horny shell development in turtles

The hypothesis that horny scutes develop from a mosaic of placodes corresponding exactly to the paths of myoseptae, with vertebral and pleural scute developing staggered in adjacent segments, and marginal scutes developing in every segment is tested.

Homeotic shift at the dawn of the turtle evolution

It is demonstrated that the Late Triassic turtles indicate that the shift of the boundary between the cervical and dorsal sections of the vertebral column occurred over the course of several million years after the formation of complete carapace.

Delayed trait development and the convergent evolution of shell kinesis in turtles

It is proposed that delayed trait differentiation via tissue repatterning might facilitate phenotypic diversification and innovation that otherwise would not arise due to developmental constraints.

Shell variability in the stem turtles Proterochersis spp.

Presented data supplement the sparse knowledge of shell scute development in the earliest turtles and suggest that at least some aspects of the developmental programs governing scutes development were already similar in the Late Triassic to these of modern forms.

Shell Anomalies in the European Aquatic Stem Turtle Pleurosternon bullockii (Paracryptodira, Pleurosternidae)

The uppermost Jurassic to lowermost Cretaceous stem turtle Pleurosternon bullockii is the pleurosternid (Testudinata, Paracryptodira) known by the largest number of specimens worldwide, composing the

On the validity of the British Upper Jurassic turtle “Pleurosternon portlandicum” (Paracryptodira, Pleurosternidae)

Pleurosternidae is a clade of North American and European Mesozoic turtles known from the Late Jurassic to the Early Cretaceous. The knowledge about the European record of this group has



Patterns of scute development in turtle shell: Symmetry and asymmetry

The scute mosaic (pholidosis) in the turtle shell is characterized by two phenomena: phylogenetic stability of the general body plan and wide individual variability. The study of turtle morphogenesis

The origin and loss of periodic patterning in the turtle shell

It is shown that scutes develop from an array of patterned placodes and that these placodes are absent from a soft-shelled turtle in which scutes were lost secondarily, and how two coupled reaction-diffusion systems reproduce both natural and abnormal variation in turtle scutes is shown.

The integumental appendages of the turtle shell: an evo-devo perspective.

In this estimation, the scutes of the turtle shell are an evolutionary novelty, whereas the tubercles found on the shells of some turtles are homologous to reptilian scales.

An ancestral turtle from the Late Triassic of southwestern China

A new 220-million-year-old turtle from China is described that documents an intermediate step in the evolution of the shell and associated structures and shows that the turtle shell is not derived from a fusion of osteoderms.

Evo-Devo of amniote integuments and appendages.

In mammals, tilting the balance of the BMP pathway in K14 noggin transgenic mice alters the number, size and phenotypes of different ectodermal organs, making investigators rethink the distinction between morpho-regulation and pathological changes.

Variation in the Plastral Formulae of Selected Turtles with Comments on Taxonomic Utility

The results of this study demonstrate that a given species may be represented by as many as 35 plastral formulae, while closely related forms may exhibit a high degree of overlap.

Reptile scale paradigm: Evo-Devo, pattern formation and regeneration.

The purpose of this perspective is to highlight the merit of the reptile integument as an experimental model and underscore how further development of this novel experimental model will be valuable in filling the gaps of the authors' understanding of the Evo-Devo of amniote integuments.

The present review focuses on past and recent information on the evolution of reptilian epidermis and the stratum corneum, and the evolutions of the horny layer in Therapsids and Saurospids (reptiles and birds).

Anatomy and relationships of the turtle Boremys pulchra (Testudines: Baenidae)

It is concluded that the derived characters of the carapace and plastron that had previously defined the Eubaeninae but are not present in Boremys have arisen independently within the subfamily.

Pareiasaur phylogeny and the origin of turtles

Many features thought to be restricted to turtles (and thus to have evolved simultaneously with the turtle shell) actually arose earlier, at various points along the pareiasaurian stem lineage.
