The Anatomical Record, EarlyView.Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

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

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)
The Anatomical Record, EarlyView.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.

Morphometry of stylomastoid foramen and its clinical application in facial nerve block
Saudi Journal of Anaesthesia, 2015 Background: Stylomastoid foramen is an important site for Nadbath facial nerve block. Exact localization of foramen holds the key to success, thus decreasing the complications. Wide racial variation exists in position of stylomastoid foramen in different

Unfused transverse foramen of the atlas vertebra in the Neandertal lineage fossils
The Anatomical Record, EarlyView.Abstract In anatomically modern humans, the atlas can display an unfused transverse foramen (UTF) but currently the presence of UTF in the Neandertal lineage is uncertain due to a scarcity of prevalence studies and no exhaustive record of its presence throughout the entire hominin fossil record.

A morphological and morphometric study of foramen ovale in dry skulls of Indian population
National Journal of Clinical Anatomy, 2019 Background and Aim The foramen ovale is a clinically significant foramen present in the skull base. The mandibular nerve is an important structure traversing this foramen and the trigeminal ganglion is also located just above the foramen ovale in the ...

The Anatomical Record, EarlyView.Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

The 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
