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

The 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)

The 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

The tiger salamander as a promising alternative model organism to the axolotl for fracture healing and regenerative biology research

The Anatomical Record, EarlyView.
Abstract Scientists have been captivated by the ability to regenerate, focusing on uncovering the mechanisms of epimorphic regeneration and applying them to human medicine. The axolotl (Ambystoma mexicanum) has become the most intensively studied model in tetrapod regeneration research, particularly concerning limb regeneration.
