Cynosphenodon (/ˌsnəˈsfɛnədɒn/ SY-nə-SFEN-ə-don; "Dog Sphenodontian") is an extinct genus of rhynchocephalian in the family Sphenodontidae from the Middle Jurassic La Boca Formation of Tamaulipas, Mexico. It is known from a largely complete lower jaw and fragments of the upper jaw. It is suggested to be among the closest known relatives of the tuatara, with both being placed in the Sphenodontinae,[1] which is supported by among other characters, the growth pattern of the teeth.[2]

Le drapeau rouge est le principal symbole du socialisme et du communisme à leur commencement.
