The
squamosal is a bone of the head of
higher vertebrates. It is the principal component of the cheek region in the skull, lying below the temporal series and
otic notch and bounded anteriorly by the
postorbital. Posteriorly, the squamosal articulates with the posterior elements of the palatal complex, namely the
quadrate and
pterygoid. The squamosal is bordered anteroventrally by the
jugal and ventrally by the
quadratojugal.
