In tetrapods with a quadratojugal bone, it often forms a portion of the jaw joint. Developmentally, the quadratojugal bone is a dermal bone in the temporal series, forming the original braincase. The squamosal and quadratojugal bones together form the cheek region [4] and may provide muscular attachments for facial muscles. [5]
The quadrate bone is a skull bone in most tetrapods, including amphibians, sauropsids (reptiles, birds), and early synapsids. In most tetrapods, the quadrate bone connects to the quadratojugal and squamosal bones in the skull, and forms upper part of the jaw joint. The lower jaw articulates at the articular bone, located at the rear end of the ...
The posterior end of the lower jaw bones contains a quadrate bone, allowing jaw extension. The anterior tips of the lower jaw bones are joined by a flexible ligament allowing them to bow outwards, increasing the mouth gape. [74] [75] The Pacific tree frog and the Baja California chorus frog are some of the only frog species that make a "ribbit ...
The squamosal is a skull bone found in most reptiles, amphibians, and birds. In fishes, it is also called the pterotic bone. [1] In most tetrapods, the squamosal and quadratojugal bones form the cheek series of the skull. [2] The bone forms an ancestral component of the dermal roof and is typically thin compared to other skull bones. [3]

Psychological typologies are classifications used by psychologists to describe the distinctions between people. The problem of finding the essential basis for the classification of psychological types —that is, the basis of determining a broader spectrum of derivative characteristics—is crucial in differential psychology .
A correspondingly large intervomerine fontanelle is found on the palate. The quadratojugal is expanded, and in Acanthostomatops and Zatrachys, bears discrete spiky projections. The quadratojugal also obscures the quadrate in dorsal profile. Dasyceps and Zatrachys are only confidently known from cranial material.
