Extremely unlikely for the "classic" synapsids. Despite the fact the clade's
name comes from a single character state, it is
supported by a number of derived characters from various parts of the skeleton.
That said, it has been occasionally suggested that Diadectes is a basal
synapsid, although the majority of studies place it outside
