Early tetrapod possessed a primary palate that included the vomer, pterygoid, parasphenoid, palatine and ectopterygoid bones. Therapsid evolved a partial secondary palate formed by the medial extension of the premaxilla and maxilla. Mammals have a secondary palate that, in addition to extensions of the premaxilla and maxilla, includes part of the palatine bone[VHOG]
