Osteoporosis and the risk of fracture

open access: yesSouth African Family Practice, 2005
Osteoporosis is a skeletal disease characterised by low bone mass and a deterioration of the microarchitecture of bone tissue, leading to an increase in bone fragility and a greater risk of fracture.

Inside a duck‐billed dinosaur: Vertebral bone microstructure of Huallasaurus (Hadrosauridae), Upper Cretaceous of Patagonia

open access: yesThe Anatomical Record, EarlyView.
Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

A contribution to the anatomy of two rare cetacean species: The hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica)

open access: yesThe Anatomical Record, EarlyView.
Abstract The anatomical description of the hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica) remains largely unexplored, due to limited specimen availability and preservation challenges. This study employed digital imaging techniques, conventional histology, and computed tomography to provide visualization of

Functional anatomy, jaw mechanisms, and feeding behavior of Dunkleosteus terrelli (Placodermi, Arthrodira)

open access: yesThe Anatomical Record, EarlyView.
A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

Histology and fossil diagenesis of a pterosaur tooth from the Crato Formation (Lower Cretaceous of Brazil)

open access: yesThe Anatomical Record, EarlyView.
Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

Re‐evaluation of a soft crested Edmontosaurin, with implications for hadrosaurid life appearance and diversity

open access: yesThe Anatomical Record, EarlyView.
Abstract Hadrosaurid dinosaurs are generally regarded as “crested” or “non‐crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non‐crested” hadrosaur is known to have possessed a soft tissue cranial crest (or comb), based on an exceptionally preserved “mummified” specimen. Here we redescribe this specimen and

Nasal soft‐tissue anatomy of Triceratops and other horned dinosaurs

open access: yesThe Anatomical Record, EarlyView.
Abstract Although ceratopsid dinosaurs possess a characteristically hypertrophied narial region, soft‐tissue anatomy associated with such a skeletal structure and their biological significance remain poorly understood. The present study provides the first comprehensive hypothesis on the soft‐tissue anatomy in the ceratopsid rostrum based on the Extant ...
