The variability of giraffe skull morphology

open access: yesJournal of Anatomy, Volume 249, Issue 5, Page 1068-1086, November 2026.
What does giraffe skull shape tell us about their development and evolution? Abstract Giraffe (Giraffa spp.) are among the most unique and charismatic extant animals, largely due to their distinct morphology. The evolutionary and developmental origin of ossicones is a key factor in giraffid biology, yet other features building their characteristic head

Concurrent Long Thoracic and Lateral Cutaneous Intercostal Nerve Entrapment After Chest Tube Thoracostomy Causing Scapular Winging and Chest Wall Pain: Diagnosis With Ultrasound and Treatment With Hydrodissection

open access: yesPain Practice, Volume 26, Issue 8, November 2026.
ABSTRACT Background Chest tube thoracostomy may cause iatrogenic nerve injury, resulting in persistent pain and functional impairment. Long thoracic nerve (LTN) palsy after chest tube placement has been described, but concurrent involvement of the LTN and the lateral cutaneous branch of an intercostal nerve (LCIN) appears to be rarely reported.

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

open access: yesThe Anatomical Record, Volume 309, Issue 10, Page 2574-2635, October 2026.
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 ...

A COMPARISON OF ENDOCRANIAL OCCIPITAL BONE MORPHOLOGY IN MODERN HUMAN AND FOSSIL HOMININS

open access: yes
The evolution of cranial morphology in the genus Homo has been characterized by a trend of encephalization [1]. The occipital bone is one of the most studied cranial regions to infer the taxonomic status of human fossil individuals.

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

open access: yesThe Anatomical Record, Volume 309, Issue 10, Page 2656-2697, October 2026.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

open access: yesThe Anatomical Record, Volume 309, Issue 10, Page 2873-2896, October 2026.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.
