A Permian fish reveals widespread distribution of neopterygian-like jaw suspension
eLife, 2022 The actinopterygian crown group (comprising all living ray-finned fishes) originated by the end of the Carboniferous. However, most late Paleozoic taxa are stem actinopterygians, and broadly resemble stratigraphically older taxa.

Evolution of jaw disparity in fishes [PDF]
Palaeontology, 2018 AbstractThe morphology of the vertebrate lower jaw has been used to infer feeding ecology, with transformations in mandibular shape and structure likely to have facilitated the emergence of different feeding behaviours in vertebrate evolution. Here we present elliptical Fourier shape and principal component analyses, characterizing and comparing the ...

Evolution and development of the fish jaw skeleton
WIREs Developmental Biology, 2018 The evolution of the jaw represents a key innovation in driving the diversification of vertebrate body plans and behavior. The pharyngeal apparatus originated as gill bars separated by slits in chordate ancestors to vertebrates. Later, with the acquisition of neural crest, pharyngeal arches gave rise to branchial basket cartilages in jawless ...

Quality test of long-jawed mackerel (Rastrelliger sp.) fish flour
Food Research, 2020 This research was aimed to evaluate the quality of long-jawed mackerel fish flour, resulted from four different treatments, based on specific criteria, namely water content, protein, fat and calcium. This was a True Experimental Design Post test-Only Control Design research with a completely randomized design (CRD). The experimental method consisted of

A Mechanical Approach for Comparing Jaws in Fishes
BiomimeticsThis paper aims to propose an quantitative engineering approach to study and compare the jaw mechanisms of different marine species, considering essential mechanical parameters generally used to evaluate the performance of industrial linkage mechanisms ...

Late Jurassic jaw bones of Halecomorph fish (Actinopterygii: Halecomorphi) studied with X-ray microcomputed tomography [PDF]
Palaeontologia Electronica, 2015 New finds of Halecomorphi fish remains from Late Jurassic limestones of Owadow-Brzezinki (Poland) are investigated using X-ray microcomputed tomography (XMT) revealing details of jaw bones for actinopterygian fish histology. Three-dimensional (3-D) reconstruction allows for correct taxonomical verification.

Sclerotic plates or circumorbital bones in early jawed fishes? [PDF]
Palaeontology, 2010 Abstract: Circumorbital dermal bones are found in most groups of early vertebrates that have dermal bony plates on the head. Taxonomic distribution of dermal sclerotic plates on the eye itself is less clear, partly because the eyeball is rarely preserved and sometimes because sclerotic bones have been misinterpreted as circumorbital bones.

Jaw protrusion enhances forces exerted on prey by suction feeding fishes [PDF]
Journal of The Royal Society Interface, 2008 The ability to protrude the jaws during prey capture is a hallmark of teleost fishes, widely recognized as one of the most significant innovations in their diverse and mechanically complex skull. An elaborated jaw protrusion mechanism has independently evolved multiple times in bony fishes, and is a conspicuous feature in several of their most ...

A classic key innovation constrains oral jaw functional diversification in fishes [PDF]
Evolution LettersAbstract Modifications to the pharyngeal jaws—a prey processing system located posterior to the mouth cavity—are widely considered a key innovation that enhanced diversification within several prominent fish clades. Seen in cichlids, damselfishes, wrasses, and a few other lineages, these musculoskeletal alterations are believed to ...
