WebCynodonts, which first appeared in the Late Permian period 260 million years ago, are thought to be the ancestors of modern mammals. (credit: Nobu Tamura) Mammals are synapsids, meaning they have a single opening in the skull. They are the only living synapsids, as earlier forms became extinct by the Jurassic period. WebCynodonts, one of the most diverse groups of therapsids, are named after their dog-like teeth. The taxon is a clade which includes modern mammals and their extinct close relatives, the Mammaliaformes. The cynodonts lived in all continents, and their fossil record begins in the Upper Permian 256 million years ago. [3]
