The periosteal cortex in the shaft of limb bones is described histologically in three ichthyosaurian genera, Omphalosaurus, Stenopterygius, and Ichthyosaurus. The primary periosteal deposits are composed of typical woven-fibered tissue that was accreted as spongy bone in young individuals, and more or less compact bone in older individuals. During growth, the bone tissue was extensively remodeled with a quantitative imbalance between resorption and redeposition. As a result, the cortex was made… 

Structural, functional, and physiological signals in ichthyosaur vertebral centrum microanatomy and histology

The main switch in microanatomical organization appears to be correlated to the acquisition of deeply amphicoelous disk-like vertebral centra rather than to a shift in swimming mode from long and slender-bodied anguilliform swimmers to thunniform swimming.

Ecomorphology and bone microstructure of Proterochampsia from the Chañares Formation

Proterochampsians are a South American endemic group of non-archosaurian archosauriforms with morphological characteristics recollecting Recent crocodilians, and therefore have been proposed as

Preliminary Observations on the Bone Histology of the Middle Triassic Pseudosuchian Archosaur Batrachotomus kupferzellensis Reveal Fast Growth with Laminar Fibrolamellar Bone Tissue

Compared with most other Pseudosuchia (e.g., phytosaurs, aetosaurs, and most crocodylomorphs, including marine taxa), Batrachotomus achieved its large body size in a very short time by fast, although interrupted, growth and not by protracted longevity.

Bone histology as a clue in the interpretation of functional adaptations in the Thalattosuchia (Reptilia, Crocodylia)

The histological study of various bones in the families Teleosauridae and Metriorhynchidae reveals common, but also contrasting structural features of the skeleton, suggesting a cyclic growth and an ecto-poikilothermic physiology.

Osteology of a perinatal aristonectine (Plesiosauria; Elasmosauridae)

The presence of a perinatal specimen in the James Ross Archipelago indicates that the region was used as a breeding area by the aristonectines during the last part of the Cretaceous.

Rib and vertebral micro-anatomical characteristics of hydropelvic mosasauroids

Houssaye, A. & Bardet, N. 2011: Rib and vertebral micro-anatomical characteristics of hydropelvic mosasauroids. Lethaia, Vol. 45, pp. 200–209. Mosasauroids are squamates secondarily adapted to

Bone histology of Azendohsaurus laaroussii: Implications for the evolution of thermometabolism in Archosauromorpha

A parsimony optimization of the presence of endothermy on a phylogenetic tree of tetrapods shows that this derived character state was acquired by the last common ancestor of the clade Azendohsaurus–Archosauriformes and that there is a reversion in Crocodylia.

Long bone histology and microanatomy of Placodontia (Diapsida: Sauropterygia)

Differences in microanatomy and bone histology as expressed by a principal component analysis clearly indicate different paleoecologies, including differences in lifestyle and swimming modes and capabilities in Placodontia.

New biological insights into the Middle Triassic capitosaurs from India as deduced from limb bone anatomy and histology

Woven fibred bone tissue, a very rapidly deposited tissue mostly seen in the embryos and very young individuals of higher vertebrates, is reported for the first time in a juvenile temnospondyl suggesting that such tissues in non‐amniotes helped in achieving large body sizes rapidly.

Chondro-osseous morphology of Dermochelys coriacea, a marine reptile with mammalian skeletal features

The chondro-osseous morphology of Dermochelys is unlike that of any other known extant turtle or reptile but is more similar to that of marine mammals, notably Cetacea (whales) and Sirenia (manatees).

On how the periosteal bone of the delphinid humerus becomes cancellous: Ontogeny of a histological specialization

The ontogenetic basis of these characters in terms of the ontogeny of the structure and textural bone compactness of the humeral diaphysis in a growth series of common dolphins (Delphinus delphis) is discussed.

Some structural and developmental characteristics of cetacean (odontocete) radii. A study of adaptive osteogenesis.

It is suggested that some of the characteristics of growth and structure, including an apparent periodicity in structural density, may be related to temperature and vascular supply in the high-area, low-volume flipper in colder waters.

Comparative Chondro-osseous Development and Growth of Marine Turtles

Skeletal growth in Dermochelys coriacea is remarkably divergent from other living chelonians and may be due to very rapid skeletal growth to a large body size.

STRUCTURAL ORIENTATION AND DENSITY IN CETACEAN HUMERI.

The spongy cetacean humerus, from its origin, is without central resorption and that its definitive structure is produced primarily by differential concentration of bone along endoectad gradients of porosity, a most reasonable approximation of the engineered box-beam as employed in some aircraft wings.

The weight and structural characteristics of bones were compared between a small delphinid (Delphinus delphis L.) and a terrestrial mammal and showed the morphological correlates of the steep reduction in skeletal mass, which is a characteristic of dolphins.

Metabolism of leatherback turtles, gigantothermy, and thermoregulation of dinosaurs

It is indicated that leatherbacks can use large body size, peripheral tissues as insulation, and circulatory changes, to maintain warm temperatures in the North Atlantic and to avoid overheating in the tropics.
