A second species of non‐crocodyliform crocodylomorph from the Late Triassic fissure deposits of southwestern UK: Implications for locomotory ecological diversity in Saltoposuchidae

The Anatomical Record, EarlyView.
Abstract The Late Triassic–Early Jurassic fissures of the Bristol Channel area (southwest England and south Wales) are renowned for their diverse vertebrate faunas. These assemblages have yielded an array of predominantly small‐bodied forms that are crucial to our understanding of the early evolution of several major tetrapod clades.

Cemento-ossifying fibroma of maxillary antrum in a young female patient

Journal of Indian Society of Pedodontics and Preventive Dentistry, 2011
The cemento-ossifying fibroma is classified as a fibro-osseous lesion of the jaws. It commonly presents as a progressively growing lesion that can attain an enormous size with resultant deformity if left untreated.

MicroCT reinvestigation of the only articulated fossil anostomid fish reveals synonymy of Arhinolemur Ameghino, 1898 and Megaleporinus Ramirez et al., 2017

The Anatomical Record, EarlyView.
Abstract Arhinolemur scalabrinii† Ameghino, 1898 was originally described as a strepsirrhine primate (Mammalia) but has been recognized as an anostomid fish since 2012. It remains the only extinct anostomid species known from complete cranial material.

Mandibular mass in pediatric patient: A diagnostic dilemma

Journal of Indian Society of Pedodontics and Preventive Dentistry, 2012
A case of aggressive Juvenile ossifying fibroma in a child has been discussed. The unique appearance of this particular lesion demonstrates a close relationship between aggressive ossifying fibroma and well-differentiated osteogenic sarcoma.

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

The Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

The petrotympanic canal (Huguier canal): Evolutionary, anatomical, and medical perspectives

The Anatomical Record, EarlyView.
Abstract The petrotympanic canal, traditionally referred to as Civinini's or Huguier's canal, represents an anatomical passage connecting the middle ear and temporomandibular joint (TMJ). Despite its early description, its structural complexity and functional significance have often been underestimated. In this study, we combined historical, anatomical,

Early evolution of the gular musculature and its innervation in ray‐finned fishes

The Anatomical Record, EarlyView.
Abstract Gular muscles are an important but often overlooked component of cranial anatomy in bony fishes. They are located on the ventral surface of the head and are derived from the mandibular and hyoid arches. We present a comprehensive review of the gular musculature and its innervation across early diverging actinopterygian lineages. By integrating

Oldest well‐preserved euprimate petrosal, from the early Eocene of India (Vastan Lignite Mine, Gujarat)

The Anatomical Record, EarlyView.
Abstract An exquisitely preserved, isolated partial petrosal with associated fragmentary stapes is described from the Vastan Lignite Mine (Gujarat, India), dated to the early Eocene (~54.5 Ma). Several anatomical traits (e.g., large petrosal plate; posterolateral entry of the internal carotid artery to the tympanic cavity; bony tubes surrounding the ...

Juvenile trabecular ossifying fibroma of maxilla

Saudi Journal of Oral Sciences
Ossifying fibroma is a rare tumor formed by abnormal cells in the ligament. There are two types of ossifying fibroma: central and peripheral. A 20-year-old female patient experienced pain and swelling on the right side of her face for one year.
