Synapsida is a diverse group of tetrapod vertebrates that includes all mammals and their extinct relatives. It is one of the two major clades of the group Amniota, the other being the more diverse group Sauropsida.

These openings create a bony arch that allows for the attachment of larger jaw muscles and a more efficient bite.
