Sclerotic plates or circumorbital bones in early jawed fishes?
Palaeontology, 2010Abstract: 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.

Acanthodian fishes with dentigerous jaw bones: the Ischnacanthiformes and Acanthodopsis
2004Within the early gnathostome group Acanthodii, several different types of dentition are exhibited. Of the Siluro-Devonian acanthodians, some of the Climatiidae and the Brochoadmonidae have rows of small tooth whorls lining their jaws, while the Ischnacanthidae and Poracanthodidae have dermally derived dentigerous jaw bones, with some taxa also having a

Mechanics and Functions of Jaw Protrusion in Teleost Fishes: A Review
Copeia, 1984The more recent and definitive studies on the mechanics and functions of jaw protrusion in teleost fishes are reviewed. Four basic mechanisms characterize the system: In the Type A or "mandible depression model" of jaw protrusion, depression of the mandible pulls or pushes the premaxilla into the protruded state.

Two patterns of differentiation in the jaw musculature of teleostean fishes
Journal of Zoology, 1989In its most generalized configuration among modern teleosts the M. adductor mandibulae comprises a single, almost continuous mass of musculature extending from the cheek to the inner surface of the mandible. In more advanced teleosts this muscle is usually divided into sections.
