What is Squamosal bone?
[[Image:Skull synapsida 1.png|thumb|200px|'''Sq''' = squamosal]] The '''squamosal''' is a bone of the head of [[amniote|higher vertebrate]]s. It is the main part of the [[cheek]] region in the [[skull]], towards the back and lower part of the skull.<ref>{{Cite book| last = Romer | first = A.S. | title = Osteology of the reptiles| publisher = University of Chicago Press | year = 1956 | page = 772 }}</ref> In mammals, including humans, it fuses with other bones to form the [[temporal bone]]. It is then called the 'squama temporalis'. In [[Therapsida|therapsids]] (including [[mammal]] ancestors) the lower jaw is simplified into just the [[dentary]]. This hinges against the squamous part of the temporal bone. It is referred to as a 'dentary-squamosal jaw'.<ref>{{Cite web|last=Carr|first=Steven M.|year=2005|title=Quadroarticular vs dentary-squamosal jaw|url=https://www.mun.ca/biology/scarr/QA_vs_DS_jaw.html|publisher=Memorial University of Newfoundland|accessdate=1 August 2012}}</ref> == References == {{reflist}} [[Category:Bones]] [[Category:Bones of the skull]]
