ABSTRACT The long bone histology of the “hypsilophodontid” dinosaurs Orodromeus makelai, Dryosaurus altus, and Tenontosaurus tilletti, was examined from perinate to largest available ontogenetic stages. These ontogenies were compared with each other, and to those of other dinosaurs, notably hadrosaurids such as Maiasaura and Hypacrosaurus. Orodromeus is a small dinosaur, and its more moderate growth trajectory is consistent with those generally observed for relatively small dinosaurs and… 
Ontogeny in the tube-crested dinosaur Parasaurolophus (Hadrosauridae) and heterochrony in hadrosaurids
TLDR
The skull and skeleton of a juvenile Parasaurolophus from the late Campanian-aged Kaiparowits Formation of southern Utah, USA, represents the smallest and most complete specimen yet described for this taxon.
The Ontogenetic Osteohistology of Tenontosaurus tilletti
  • S. Werning
  • Environmental Science, Geography
    PloS one
  • 2012
TLDR
The bone histology of T. tilletti indicates a much slower growth trajectory than observed for other iguanodontians, suggesting that those taxa reached much larger sizes than Tenontosaurus in a shorter time.
Biological Implications of the Bone Microstructure of the Late Cretaceous Ornithopod Dinosaur Gasparinisaura cincosaltensis
TLDR
The bone histology of Gasparinisaura cincosaltensis, a basal ornithopod from the Late Cretaceous of Patagonia, is presented and it is suggested that the attainment of sexual maturity occurred before skeletal maturity.
Comparative bone histology of rhabdodontid dinosaurs
TLDR
Qualitative comparison of bone histology of corresponding ontogenetic stages and elements among the three valid rhabdodontid genera, Mochlodon, Zalmoxes, and Rhabdodon, revealed some consistent patterns, which indicate a prolonged phase of fast growth and a less constrained cyclicity in the growth dynamics of R Habdodon.
Osteohistological insight into the early stages of growth in Mussaurus patagonicus (Dinosauria, Sauropodomorpha)
TLDR
The bone histology of juvenile specimens of the basal sauropodomorph Mussaurus patagonicus is described and its significance is interpreted in terms of the early growth dynamics of this taxon.
Bone histology of varanopids (Synapsida) from Richards Spur, Oklahoma, sheds light on growth patterns and lifestyle in early terrestrial colonizers
TLDR
It is shown that bone histology has the potential to explain how ballast was shed and the skeleton lightened for terrestrial mobility in ancestral synapsids and their basal amniote kin, as well as how adjustments in postnatal growth influenced the evolution of larger body sizes in the terrestrial frontier.
A reappraisal of Notohypshilophodon comodorensis (Ornithischia: Ornithopoda) from the Late Cretaceous of Patagonia, Argentina.
TLDR
A restudy of Notohypsilophodon is presented, which increases the knowledge of the evolutionary dynamics of South American Cretaceous ornithopods, and broadens theknowledge of the early Late Cret Jurassic continental vertebrate assemblages of central Patagonia and of the Southern Hemisphere in general.
Phylogeny, Histology and Inferred Body Size Evolution in a New Rhabdodontid Dinosaur from the Late Cretaceous of Hungary
TLDR
Rhabdodontid remains from the Santonian of western Hungary provide evidence for a new, small-bodied form, which is assigned to Mochlodon vorosi n.

GROWTH IN SMALL DINOSAURS AND PTEROSAURS: THE EVOLUTION OF ARCHOSAURIAN GROWTH STRATEGIES
TLDR
The evolution of life history strategies in dinosaurs and pterosaurs, as they relate to rates of growth and adult body sizes, will be better understood as more complete histological studies place these data into phylogenetic and ontogenetic contexts.

TLDR
A new sampling technique for fossil bone (coring with a 5/8” bit) was used to sample longbones of all four sauropod genera from the Upper Jurassic Tendaguru beds of Tanzania for paleohistological study, showing a common growth pattern in which growth is determinate but sexual maturity is achieved well before maximum size is reached.
LONG BONE HISTOLOGY OF THE HADROSAURID DINOSAUR MAIASAURA PEEBLESORUM: GROWTH DYNAMICS AND PHYSIOLOGY BASED ON AN ONTOGENETIC SERIES OF SKELETAL ELEMENTS
TLDR
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).
Comparative osteohistology of some embryonic and perinatal archosaurs: developmental and behavioral implications for dinosaurs
TLDR
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.
Sexual maturity in growing dinosaurs does not fit reptilian growth models
TLDR
It is shown by counting lines of arrested growth and performing growth curve reconstructions that Tenontosaurus, Allosaurus, and Tyrannosaurus were reproductively mature by 8, 10, and 18 years, respectively, which suggests that these dinosaurs were born relatively precocial and experienced high adult mortality.
Sizing the Jurassic theropod dinosaur Allosaurus: Assessing growth strategy and evolution of ontogenetic scaling of limbs
TLDR
Phylogenetic optimization suggests that large theropods independently evolved reduced humeral, ulnar, and tibial lengths by a phyletic reduction in longitudinal growth relative to the femur.
Variation in dinosaur skeletochronology indicators: implications for age assessment and physiology
TLDR
Twelve different bones from the skeleton of the holotype specimen of the hadrosaurian dinosaur Hypacrosaurus stebingeri were thin-sectioned to evaluate the significance of lines of arrested growth (LAGs) in age assessments, finding the tibia was found to have experienced the least amount of reconstruction, but was still not optimal for skeletochronology.
Systematics of hypsilophodontidae and basal Iguanodontia (dinosauria: Ornithopoda)
TLDR
Based on analyses, Hypsilophodontidae constitutes a monophyletic taxon that comprises the sister taxon to Iguanodontia, together forming Euornithopoda.
Ontogenetic histology of Apatosaurus (Dinosauria: Sauropoda): New insights on growth rates and longevity
TLDR
All Apatosaurus bones sampled corroborate the hypothesis of sustained rapid growth rates for most of ontogeny, followed by gradual decline with attainment of maximum size, as well as regular variation in speeds of osteogenesis.
Dinosaurian precursors from the Middle Triassic of Argentina: Marasuchus lilloensis, gen. nov.
TLDR
Several synapomorphies unite Marasuchus and dinosaurs (as Dinosauriformes) to the exclusion of the contemporary dinosauromorph Lagerpeton and pterosaurs.
