Osteohistological insight into the growth dynamics of early dinosaurs and their contemporaries.

PLoS ONE
Dinosauria debuted on Earth's stage in the aftermath of the Permo-Triassic Mass Extinction Event, and survived two other Triassic extinction intervals to eventually dominate terrestrial ecosystems.

Bone labeling experiments and intraskeletal growth patterns in captive leopard geckos (Eublepharis macularius)

Journal of Anatomy, Volume 247, Issue 3-4, Page 542-555, September/October 2025.
In this study, we used fluorochrome labels in captive leopard geckos (Eublepharis macularius) to track bone growth and intraskeletal variability from embryonic to adult growth stages. Overall, the tibia in leopard geckos is the least reliable limb bone to use for skeletochronology and the humerus, radius, and fibula preserve the longest growth record ...

Intraskeletal histovariability and skeletochronology in an ornithopod dinosaur from the Maestrazgo Basin (Teruel, Spain)

Journal of Anatomy, Volume 247, Issue 3-4, Page 643-664, September/October 2025.
Abstract Ornithopods are an extinct group of dinosaurs that were particularly abundant and diverse in the Cretaceous of the Iberian Peninsula, and whose abundance in the Maestrazgo Basin has allowed numerous taxa to be identified over the last decade. Many of these fossil remains are still taxonomically indeterminate and require a more detailed study ...

Cancellous bone and theropod dinosaur locomotion. Part I—an examination of cancellous bone architecture in the hindlimb bones of theropods [PDF]

, 2018
This paper is the first of a three-part series that investigates the architecture of cancellous (‘spongy’) bone in the main hindlimb bones of theropod dinosaurs, and uses cancellous bone architectural patterns to infer locomotor biomechanics in extinct ...

Palaeobiology and osteohistology of South African sauropodomorph dinosaurs

Journal of Anatomy, Volume 247, Issue 3-4, Page 712-727, September/October 2025.
We found that the transitionary Sauropodiformes show both the traits of rapid growth of derived Sauropoda as well as interrupted growth of early branching Sauropodomorpha. There appears to be much more variation in growth dynamics of Sauropodiformes than initially thought.

The effects of the spreading of the Central Atlantic during the Middle Jurassic on dinosaur faunas [PDF]

, 2012
The spreading of the Central Atlantic is a complex series of events that include a ridge jump to the east and a ridge jump to the west at c. 170Ma and c. 162Ma respectively.

Dynamics of dental evolution in ornithopod dinosaurs. [PDF]

, 2016
Ornithopods were key herbivorous dinosaurs in Mesozoic terrestrial ecosystems, with a variety of tooth morphologies. Several clades, especially the 'duck-billed' hadrosaurids, became hugely diverse and abundant almost worldwide.

Skull morphology and histology indicate the presence of an unexpected buccal soft tissue structure in dinosaurs

Journal of Anatomy, Volume 247, Issue 3-4, Page 790-818, September/October 2025.
A combined approach of osteology and histology was used to examine the cheek regions of dinosaurs. Strong evidence was found for a soft tissue in this region connecting the zygoma to the mandible, here named the ‘exoparia’. Abstract Unlike mammals, reptiles typically lack large muscles and ligaments that connect the zygoma to the mandible.
