The Synapsids, or mammal-like reptiles, were the dominant land animals of the late Palaeozoic and early Triassic. They include mammals and their ancestors, the pelycosaurs, therapsids and cynodonts.
They are distinguished by the position of temporal openings in the skull behind the eyes which provides an anchor for jaw muscles, resulting in stronger jaws.
