Ptychotherates (“fold hunter”) is an extinct genus of saurischian dinosaur known from the Late Triassic (Norian or Rhaetian ages) Chinle Formation of Ghost Ranch, New Mexico, United States. The genus contains a single species, Ptychotherates bucculentus, known from a partial skull. The bone of the skull is unusually tall, deeper than in any other Triassic dinosaur. Ptychotherates is closely related to Chindesaurus, Daemonosaurus, and Tawa, together forming the clade Morphoraptora within Herrerasauria.
