An osteohistological analysis of Triceratops (Ornithischia: Ceratopsidae) cranial ornamentation
The Anatomical Record, EarlyView.Abstract Ceratopsids are among the most distinctive and well known extinct Cretaceous vertebrates, yet many details regarding the growth and composition of their cranial features are still not fully anatomically described or understood. In particular, striking cranial adornments such as the postorbital horns and parietal‐squamosal frill of Triceratops ...

Folia MorphologicaBACKGROUND: Various ligaments present in the skull base are of clinical and surgical importance. One among them, is the petrosphenoid ligament (PSL). PSL may ossify either in a partial or complete form and forms the roof of Dorello’s canal underneath ...

Heterochrony related to body size and level of skeletal ossification.
, 2015 Line leading to A represents ancestral condition. Line leading to N represents neoteny in the sense of a deceleration of rate of ossification, which produces a derived condition with a lesser degree of skeletal ossification. Line leading to D1 represents

The Anatomical Record, EarlyView.Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

Costochondral Ossification and Aging in Five Populations
, 2020 Age changes in extent of costochondral ossification of the first rib and of the lower ribs were evaluated separately from chest roentgenograms in five populations: European Americans, Lebanese, Solomon Islanders (the Lau and the Baegu), and a special ...

The internal crest anatomy of Lambeosaurini (Hadrosauridae: Lambeosaurinae)
The Anatomical Record, EarlyView.Abstract The supracranial crests of lambeosaurine hadrosaurids have long been a focus of study due primarily to their extreme morphology. The external anatomy of lambeosaurine crests is understood to be highly variable between species, but variation in their internal anatomy is less well understood.

Folia MorphologicaBACKGROUND: The development of the sternum begins during the intrauterine life and continues until the age of 25. However, specific information on the ages at which sternum development is complete remains limited.

The Anatomical Record, EarlyView.Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to
