Ontogenetic stages in the long bone histology of sauropod dinosaurs
It is hypothesize that sexual maturity was attained at HOS-8, well before maximum size was attained, but it did not find sexually differentiated growth trajectories subsequent to HOS -8, and Histologic ontogenetic stages generally correlate closely with body size and thus provide a means to resolve important issue like the ontogenetics status of questionable specimens.

A new, exceptionally preserved skull of a juvenile stem placodont from the early Middle Triassic of the Netherlands is reported, thus indicating a western Tethyan (European) origin for Placodontia, the most basal group of sauropterygians.

Pneumatic structures in the vertebral column of the specimen SMA 0009 show that pneumatisation of the postcranial skeleton had already started in this individual, giving new insights in the early ontogenetic development of vertebral pneumaticity in sauropods.
Developmental Plasticity in the Life History of a Prosauropod Dinosaur
Long-bone histology indicates that the most common early dinosaur, the prosauropod Plateosaurus engelhardti from the Upper Triassic of Central Europe, had variable life histories, and was influenced by environmental factors, as in modern ectothermic reptiles, but not in mammals, birds, or other dinosaurs.

The presence of fibrolamellar bone, which is accompanied with increased growth rates and presumably even with increased metabolic rates, already in Anarosaurus and Cymatosaurus can explain the success of the Pistosauroidea, the only sauropterygian group to survive into the Jurassic and give rise to the pelagic plesiosaur radiation.
Bone histology and its implications for the life history and growth of the Early Cretaceous titanosaur Phuwiangosaurus sirindhornae
Abstract Bone histology is the most comprehensive way of obtaining data on growth and life history for dinosaurs. Humeri and femora of the basal titanosaur Phuwiangosaurus sirindhornae from the Early…

The reduction of growth rate indicated by MLB is coupled with a drastic body size reduction and maybe also a reduction in metabolic rate, interpreted as a result of dwarfing on the European islands during the Late Cretaceous.

The analysis of the various microanatomical patterns observed in long bones, vertebrae, and ribs of a large sample of (semi-)aquatic extant and extinct amniotes reveals the wide diversity in microan atomical patterns and the variation in combination of these different patterns within a single skeleton.
