An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

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 ...

Ewing′s sarcoma of maxilla in an adolescent boy

Journal of International Clinical Dental Research Organization, 2010
Ewing′s sarcoma is a rarer malignancy, occurring usually in childhood. In majority of reported cases, the occurrence of this tumor is predominantly in the mandible than in the maxilla. Prognosis remains poor in most of the cases; however, better survival

The cranial, mandibular, and hyoid anatomy of softshell turtles (Trionychidae): A revised character list for phylogenetic analysis

The Anatomical Record, EarlyView.
Abstract Softshell turtles (Pan‐Trionychidae) are an early branching clade of hidden‐necked turtles (Cryptodira) with a rich fossil record extending back to the Early Cretaceous. The evolutionary history of softshell turtles is still unresolved because of their conservative morphology combined with high levels of polymorphism related to morphological ...

Patterns of interspecific variation in labial microarchitecture among anthropoid primates and the evolution of the hominin lips

The Anatomical Record, EarlyView.
Comparative histological and semi‐automated image analysis of primate lips: Masson's trichrome‐stained sagittal sections were segmented to quantify the connective tissue, adipose, and muscular components, enabling interspecific comparisons of labial architecture.

Chondrosarcoma of maxilla

Journal of Oral and Maxillofacial Pathology, 2018
Chondrosarcoma is a rare malignant cartilaginous tumor of the head and neck region. It is a slow-growing tumor and is mostly detected in the anterior maxilla and the base of the skull. We report a case of "Grade II Chondrosarcoma" of the posterior right side of the palate invading maxillary sinus and perforating the floor of the orbit.

The skeleton of the green Iguana iguana (Squamata: Iguanidae) and its intraspecific morphological variation

The Anatomical Record, EarlyView.
Abstract The green iguana (Iguana iguana) is an iguanine lizard with herbivorous and arboreal habits, whose distribution spans through South America, Central America to the south of North America. Although the genus Iguana is well‐known, the species still lacks a comprehensive and up‐to‐date anatomical study, particularly addressing the axial skeleton,

Inverted and impacted supernumerary tooth: Case report

Muller Journal of Medical Sciences and Research, 2016
Inverted teeth have been reported in both maxilla and mandible and mostly they are inverted and impacted third molars and premolars. However, a few cases of inverted supernumerary teeth attached to an impacted third molar have been reported.

Cranial anatomy of a Late Cretaceous aspidorhynchid fish (Neopterygii: Aspidorhynchiformes) from Alberta, Canada

The Anatomical Record, EarlyView.
Abstract Belonostomus longirostrisis was named for an isolated jaw fragment from freshwater Upper Cretaceous (Campanian) sediments of the Dinosaur Park Formation of Alberta, Canada. Following the description of the Albertan species, numerous isolated cranial and postcranial elements have been collected from the Dinosaur Park Formation and assigned to B.

Rethinking brachycephaly: Anatomical implications and health considerations in lagomorphs

The Anatomical Record, EarlyView.
Abstract Brachycephaly in domestic rabbits is increasingly perceived by welfare organizations as associated with significant health complications, particularly oral pathologies. Despite this perception, comparative anatomical research into rabbit brachycephaly is limited compared to that of dogs and cats, compelling an in‐depth examination of its ...
