The lower jaw of Devonian ray‐finned fishes (Actinopterygii): Anatomy, relationships, and functional morphology

The Anatomical Record, EarlyView.
Abstract Actinopterygii is a major extant vertebrate group, but limited data are available for its earliest members. Here we investigate the morphology of Devonian actinopterygians, focusing on the lower jaw. We use X‐ray computed tomography (XCT) to provide comprehensive descriptions of the mandibles of 19 species, which span the whole of the Devonian

Panoramic radiographic study of mandibular canal and mental foramen in a selected Iranian population

SRM Journal of Research in Dental Sciences, 2016
Background and Aim: The mandibular canal and mental foramen are two important anatomic landmarks that should be noted before dental surgeries in the posterior region of the mandible. The aim of this study was to evaluate the accuracy of digital panoramic

A Rare Primary Pelvic Hydatid Cyst Presenting as Sciatica [PDF]

, 2012
Primary hydatid cyst in the pelvis is rare, and usually presents with pressure symptoms affecting the adjacent abdominal organs. We describe a rare hydatid cyst which was eroding the sacral hallow, protruding into the right sciatic foramen and presenting

A new genus and species of sabretooth, Oriensmilus liupanensis (Barbourofelinae, Nimravidae, Carnivora), from the middle Miocene of China suggests barbourofelines are nimravids, not felids [PDF]

, 2020
Since the early 2000s, a revival of a felid relationship for barbourofeline sabretooths has become popular due to recent discoveries of fragmentary fossils from Africa.

Jugular Foramen Tumors [PDF]

Skull Base, 2009
This issue has been devoted to the management of jugular foramen tumors and has been commissioned by our guest editor, Mislav Gjuric. Tumors that arise in or around the jugular foramen like paragangliomas, schwannomas, and meningiomas have always caused both surgeons and their patients very significant problems. Their resection is certainly not for the

Revisiting paravertebral muscles in European rabbits (Oryctolagus cuniculus) and European brown hares (Lepus europaeus) (Leporidae; Lagomorpha)

The Anatomical Record, EarlyView.
Abstract Domesticated European rabbits (Oryctolagus cuniculus) have long been chosen as laboratory model organisms. Despite this, there has been no definitive study of the vertebral musculature of wild rabbits. Relevant descriptions of well‐studied veterinary model mammals (such as dogs) are generally applicable, but not appropriate for a species ...

Histovariability and fossil diagenesis of Pissarrachampsa (Pseudosuchia, Notosuchia, Baurusuchidae) from the Upper Cretaceous of Southeast Brazil

The Anatomical Record, EarlyView.
Abstract Notosuchians were key components of western Gondwanan Cretaceous ecosystems in terrestrial predator niches and exhibited remarkable taxonomic and ecological diversity. Previous research has explored their physiology, metabolism, and histology, revealing varied growth patterns and life history strategies.

Computer simulation of syringomyelia in dogs [PDF]

, 2018
Syringomyelia is a pathological condition in which fluid-filled cavities (syringes) form and expand in the spinal cord. Syringomyelia is often linked with obstruction of the craniocervical junction and a Chiari malformation, which is similar in both ...
