@ElizabethS Therapsids is a group of the most advanced synapsids, and include the ancestors of mammals. Therapsids (meaning "beast face") is a class of synapsids, animals dominant on Earth during the mid to late Permian period (about 300 to 251 million years ago). Synapsids themselves are one of two major groups of amniotes (egg-laying animals), the other being sauropsids, or the true reptiles. Non-therapsid synapsids, the pelycosaurs, were actually more dominant during the Permian, but the therapsids are significant because they eventually evolved into mammals, survived the Cretaceous-Tertiary extinction that killed the dinosaurs, and went on to become the dominant group of terrestrial vertebrates, culminating in the evolution of Homo sapiens.
