Thin sections from long bones of specimens representing pterosaurs ranging from the Early Jurassic to the latest Cretaceous provide a profile of bone histology across a range of sizes, skeletal elements, growth stages, and phylogenetic positions. Most pterosaur bone is fibro-lamellar, organized in an unusual way that suggests high growth rates through ontogeny. Fibro-lamellar deposits are finished by a relatively abrupt deceleration or cessation of growth represented by lamellar, poorly… 

New insights from bone microanatomy of the Late Triassic Hyperodapedon (Archosauromorpha, Rhynchosauria): implications for archosauromorph growth strategy

Bone microanatomy of multiple postcranial skeletal elements of several individuals of Hyperodapedon collected from India is reported. This reveals that fibrolamellar bone tissue is predominant in the

Palaeobiological Implications of the Bone Histology of Pterodaustro guinazui

Data is provided that suggests that Pterodaustro attained sexual maturity at about 2 years of age, and continued to grow for a further 3–4 years doubling in size before attaining skeletal maturity, which supports the hypothesis that small Jurassic pterodactyloids took several years to reach adult body size.

LONG BONE HISTOLOGY OF THE HADROSAURID DINOSAUR MAIASAURA PEEBLESORUM: GROWTH DYNAMICS AND PHYSIOLOGY BASED ON AN ONTOGENETIC SERIES OF SKELETAL ELEMENTS

It is concluded that Maiasaura did not grow at all like living non-avian reptiles, which cannot be considered informative models for most aspects of dinosaurian growth (or physiology, to the extent that growth rates reflect metabolism).

Inter-element variation in the bone histology of Anteosaurus (Dinocephalia, Anteosauridae) from the Tapinocephalus Assemblage Zone of the Karoo Basin of South Africa

It is likely that Anteosaurus may have been more terrestrial as its osteology point towards terrestriality, but it may have occasionally inhabited ephemeral pools like modern semi-aquatic Hippopotamus.

First Pterosaur Post-Cranial Remains from the Lower Cretaceous Lohan Cura Formation (Albian) of Patagonia, Argentina

In this contribution, we present the first pterosaur post-cranial bone from the Lohan Cura Formation (Albian) of the Cerro de los Leones locality (Picun Leufu, Neuquen Province). The material is an

The palaeohistology of pterosaur bone: an overview

  • L. Steel
  • Geography, Environmental Science
  • 2008
Most pterodactyloid bones are predominantly composed of highly vascular reticular fi brolamellar bone, similar to that of most extant birds, which suggests that pterosaur bones grew rapidly, usually without interruption, until skeletal maturity was attained.

Comparative osteohistology of some embryonic and perinatal archosaurs: developmental and behavioral implications for dinosaurs

Variations in this set of histological synapomorphies overlap between birds and non-avian dinosaurs, and this overlap reinforces the hypothesis that variations in bone growth strategies in Mesozoic dinosaurs reflect different life-history strategies, including nesting behavior of neonates and parental care.

BIOMECHANICAL AND PHYSIOLOGICAL INFLUENCES ON THE OSTEOHISTOLOGICAL DEPOSITION OF ANHANGUERIA (PTEROSAURIA, PTERODACTYLOIDEA)

It is concluded that in the Anhangueria clade, the growth of bones is not compatible with the ontogenetic stage, and young animals may present large proportions, whereas there were older individuals of smaller sizes in the same clade.

The ontogeny of Pteranodon and other pterosaurs

The bone of limb-bone shafts of immature individuals is fibro-lamellar bone, which suggests that they grew rapidly to adult size, and the extensive fusion of the mature skeleton suggest that Pteranodon had determinate growth.

Differences in the Blood-Supply of Bone of Different Histological Types

The vascularization of laminar bone on the one hand and bone composed of haversian systems on the other is compared, chiefly in cattle, which has a more intimate blood-supply than haversia, and it has a larger surface area of bloodchannel per unit volume.

Spatial Organization and Mineralization of the Basal Plate of Elasmoid Scales in Osteichthyans

The various characteristic organizations of the skeletal tissues or isopedine that constitute the basal plate of osteichthyan elasmoid scales, all are varieties of bone tissue that have undergone more or less important specialization linked to the general regression of dermal ossifications and to functional adaptations.

Epigenetic mechanical factors in the evolution of long bone epiphyses

It is postulate that genotypic factors influencing the relative speed and extent of perichondral and endochondral ossification interact with mechanical epigenetic factors early in development to account for many of the morphological differences observed in vertebrate skeletons.

Skeletal growth and function in the California gull (Larus californicus)

This work addresses the conflict between development and skeletal function by analysing the ontogeny of skeletal strength in the California gull, Larus californicus, and suggests that the rate at which bones grow in length may be the rate limiting factor in wing development.

A large pterodactyloid pterosaur from the Two Medicine Formation (Campanian) of Montana

This is probably the second largest pterosaur yet known of Campanian age; its size is intermediate between the largest Pteranodon and Quetzalcoatlus northropi.

It is tentatively interpreted that the left‐handed double twisted plywood of the lower teleosteans and of Amiidae as a synapomorphy in relation to the primitive condition of an actinopterygian lineage and that the orthogonal plywood is an apoorphy among the “advanced” teleosts families.

Basal Archosaurs: Phylogenetic Relationships and Functional Implications

Erect posture has been identified as the key adaptation (possibly associated with locomotor stamina) that resulted in the archosaurian radiation.
