Frontiers in Earth Science, 2023 Islands are a classic focus for evolutionary studies. One topic of great interest has been the evolution of “dwarfs,” significantly smaller island mammals relative to their continental counterparts.

The Diagenetic Alterations of Historic Skeletons from the Crown Mines Cemetery, South Africa
Biology, 2023 Human skeletons associated with early gold mining in Johannesburg, South Africa are investigated. An unmarked cemetery was buried beneath a mine dump which resulted in macroscopically stained and poorly preserved bones.

Osteohistology of hyperodapedontine rhynchosaurs from the Upper Triassic of Southern Brazil [PDF]
Acta Palaeontologica Polonica, 2015 The first osteohistological study focused exclusively on rhynchosaurs (non-archosauriform archosauromorphs), based on the hyperodapedontines Teyumbaita sulcognathus and Hyperodapedon sp., from the Upper Triassic of Southern Brazil, indicates a relatively

New Comparative Data on the Long Bone Microstructure of Large Extant and Extinct Flightless Birds
Diversity, 2022 Here, we investigate whether bone microanatomy can be used to infer the locomotion mode (cursorial vs. graviportal) of large terrestrial birds. We also reexamine, or describe for the first time, the bone histology of several large extant and extinct ...

First record of palaeopathologies in appendicular bones of the Triassic pseudosuchians Erpetosuchidae and Aetosauria based on microstructural approaches [PDF]
Acta Palaeontologica PolonicaPseudosuchians were the dominant group of archosaurs on continental ecosystems during the Triassic. However, studies that report palaeopathologies based on osteohistological evidence in this group are scarce. Here, two cases of palaeopathologies found in

Abnormalities in Bone Mineral Density and Bone Histology in Thalassemia [PDF]
Journal of Bone and Mineral Research, 2003 Abstract This study demonstrated that there was extensive iron staining on trabecular surface and marked reduction in trabecular bone volume without significant alteration in bone formation and bone resorption rates as well as significant reduction in bone mineral density in 18 thalassemic patients.
