Jaws and teeth of the earliest bony fishes

Nature, 2007
Extant jawed vertebrates, or gnathostomes, fall into two major monophyletic groups, namely chondrichthyans (cartilaginous fishes) and osteichthyans (bony fishes and tetrapods). Fossil representatives of the osteichthyan crown group are known from the latest Silurian period, 418 million years (Myr) ago, to the present.

Fossil jawless fish from China foreshadows early jawed vertebrate anatomy

Nature, 2011
Most living vertebrates are jawed vertebrates (gnathostomes), and the living jawless vertebrates (cyclostomes), hagfishes and lampreys, provide scarce information about the profound reorganization of the vertebrate skull during the evolutionary origin of jaws.

Jaw structures and movements in higher teleostean fishes

Japanese Journal of Ichthyology, 1987
All of the diverse jaw structures in higher teleosts appear to be modifications of a single basal type and are treated as such. Only some of the principal variants are discussed. Though the two jaws act as a coordinated unit during feeding, their movements are different. The upper and lower jaws are discussed separately.

The pharyngeal jaw apparatus of labrid fishes: A functional morphological perspective

Journal of Morphology, 1986
AbstractAmong the acanthopterygian fishes, the Labridae possess the most highly integrated and specialized pharyngeal jaw apparatus. The integrated feature involves many osteological components and aspects of muscle form, architecture, composition, and function. The upper jaw articulates by means of a true diarthrosis with the pharyngeal process of the

Clinical calcium, 2005
A group of fish is not a mophyletic and includes some different classification groups. Fish are the popular name of animals which has the shape of fish. Most of fish bear jaw, but some fish do not have jaws. Formation of jaw is an important event in the history of early vertebrates. Jaws are originated from visceral arches.

Clinical calcium, 2005
Structure of Jaws in fish composed of mandibular and hyoid arches. Hyomandibular which is upper part of hyoid arch plays an important role of jaw suspension. Various jaw structures are developed in fish. One of the samples is protrusible upper jaw in cyprinid fish.
