Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola

open access: yesThe Anatomical Record, EarlyView.
Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

open access: yesThe Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

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

open access: yesThe 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 ...

Making it explicit – Sustained shared thinking dialogue as a way to explore children's perspectives on quality in German early childhood education and care

open access: yesBritish Educational Research Journal, EarlyView.
Abstract To negotiate quality in early childhood education and care, we must ask from different perspectives what constitutes a good centre for children. The children themselves have only recently been identified as a resource to contribute to that discussion.

A neuro‐behavioural model of neophobia

open access: yesBiological Reviews, EarlyView.
ABSTRACT Fear can be defined as the internal neurological state that releases a repertoire of behaviours an animal performs to reduce the effect of an aversive factor. Neophobia, the fear of novelty, is a fundamental behavioural trait observed across a wide range of species from arthropods to humans.

An unusual complication of snake bite

open access: yesThe Egyptian Journal of Internal Medicine, 2014
Anterior pituitary hypofunction is a well-known complication following snake bite. However, central diabetes insipidus as a complication of snake bite is only rarely reported in the literature. We are reporting a case of central diabetes insipidus, which

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.
