Therapsida are a group of Synapsids that include mammals and their immediate evolutionary ancestors. Synapsids are a group of reptiles with fossils aging from 320 to 100 Mya. This group includes mammals and, mammal like reptiles. These animals are classified differently than Sauropsids (birds and reptiles) because they have a single opening in their skull behind each eye (temporal fenestra) which is also true of modern mammals.
The best answer would be Therapsida.
