Endothermy, neuron counts, and other issues: Further remarks on neurocognitive evolution in fossil vertebrates

The Anatomical Record, EarlyView.
Abstract Last year, we challenged the view that large‐bodied theropod dinosaurs such as Tyrannosaurus rex resembled primates in cognition and behavior, a proposition made by Herculano‐Houzel in 2023. More recently, Jensen et al. have criticized our work on this topic, raising methodological and conceptual issues.

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.

Pathogenesis of thoracic ossification of the ligamentum flavum

Frontiers in Pharmacology
Thoracic ossification of the ligamentum flavum (TOLF) is characterized by ectopic ossification of the ligamentum flavum in the thoracic spine and is considered the main cause of thoracic spinal stenosis and spinal cord disease.

Role of soft tissue and bone interactions in the developmental integration and modularity of the skull in neural crest‐specific gap junction alpha‐1 knockout mice

The Anatomical Record, EarlyView.
Abstract The vertebrate skull is composed of bones derived from neural crest cells and mesoderm. The evolutionary capacity of the skull has been linked, in part, to the emergence of neural crest cells; however, this increased capacity for evolutionary change requires that variation within neural crest‐ and mesoderm‐derived bones remains partly ...

Sex specific knee joint soft tissue mineralization with fibrillin-1 mutation in male tight skin mice

European Cells & Materials
Background: Articular soft tissue mineralization and ossification are clear pathological signs of osteoarthritis (OA) joints. However their molecular and cellular aetiologies remain largely unknown.

Heterotopic ossification in systemic sclerosis

, 2009
Although myopathy or myositis may occur in systemic sclerosis (SSc) as well as soft tissue calcification, ossification is not a feature of the disease. Here we present an unusual case of extended calcification and, to a lesser degree, ossification of the

Scleral ossification in phthisical eyes.

, 2006
Heterotopic secondary ossification of the eye usually affects intraocular tissues. Although calcium deposition in the scleral lamellae is not uncommonly observed, bone formation is only rarely associated with chromosomal abnormalities or colobomatous ...
