The zygomatic arches are wide, there is a transverse lambdoidal ridge at the rear of the cranium and in some species, a sagittal crest running from front to back.
2.
"N . squamipes " have a larger skull that occupies well-developed supraorbital ridges and lambdoidal crests, giving the mammal great attachments for jaw muscles and a strong bite.
3.
Examples include : trigonocephaly ( fusion of the metopic suture ), brachycephaly ( fusion of the coronal suture and lambdoid suture bilaterally ), dolichocephaly ( fusion of the sagittal suture ), plagiocephaly ( fusion of coronal and lambdoidal sutures unilaterally ), and oxycephaly or turricephaly ( fusion of coronal and lambdoid sutures ).
4.
Examples include : trigonocephaly ( fusion of the metopic suture ), brachycephaly ( fusion of the coronal suture ), dolichocephaly ( fusion of the sagittal suture ), plagiocephaly ( unilateral premature closure of lambdoid and coronal sutures ), oxycephaly ( fusion of coronal and lambdoidal sutures ), Kleeblattschaedel ( premature closure of all sutures ).
