Life history data derived from the dental histological analysis of Giraffa camelopardalis: Implications for the palaeohistology of extinct giraffids

open access: yesJournal of Anatomy, EarlyView.
The study of incremental lines in the dentine (left), cementum (centre) and enamel (right) of the giraffe revealed key information about the rate and pattern of dental growth in this vertebrate. These results were also useful to obtain data on the biology and life history of the species and sets the stage for future palaeohistological analysis in ...

Illuminating the dark mess of fibers: Application of circular cross polarized light in unravelling the bone tissue structure of the dermal pectoral girdle of Metoposaurus krasiejowensis

open access: yesJournal of Anatomy, EarlyView.
Circular cross polarized light reveals the fine stucture of dermal bone tissue of a metoposaurid amphibian from the Late Triassic. Top right image shows the looped interwoven fibered bone when illuminated with circular polarized light displaying increased bone matrix intricacy compared to the same region of the bone when visualized with traditional ...

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

open access: yesJournal of Anatomy, EarlyView.
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 ...

Palaeobiology and osteohistology of South African sauropodomorph dinosaurs

open access: yesJournal of Anatomy, EarlyView.
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.

Lungfish‐like antero‐labial tooth addition and amphibian‐like enameloid‐enamel transition in the coronoid of a Devonian stem actinopterygian

open access: yesJournal of Anatomy, EarlyView.
The tooth patterning logic, which cannot be inferred from surface morphology, is revealed by visualizing buried tooth remnants in 3D. The primary teeth are added labially, initially organized in radial rows, which transition into linear rows where the coronoid becomes slender.
