''Chiniquodon'' is a genus of carnivorous cynodont, which lived during the early Late Triassic in South America. ''Chiniquodon'' is closely related to a contemporary genus, ''Probelesodon'', and close to the ancestry of mammals. Other contemporaries included early dinosaurs. As both groups filled a similar ecological niche, fairly large therapsid hunters such as ''Chiniquodon'' may have been outcompeted by dinosaurs. ==Species== ''Chiniquodon brasilensis'' *Place: The Paleontological Site Chiniquá, Santa Maria Formation *Country: Brazil, in geopark of paleorrota. *Age: Carnian, Upper Triassic Remarks: A dog-sized predator, with a skull-length of about 10 cm. This species may not have been formally published. ''Chiniquodon sanjuanensis'' *Place: Ischigualasto Formation *Country: Argentina *Age: Carnian (Upper Triassic) This skull was reassigned to this genus in 2002. It's differentiated from ''Chiniquodon theotonicus'' because of its teeth and the shape of the zygomatic process. ''Chiniquodon theotonicus'' *Place: Santa Maria Formation and Chañares Formation *Country: Brazil and Argentina *Age: Carnian (Upper Triassic) This species is known from a number of skulls. The holotype is in the paleontological collection at Tübingen University, Germany. ''Chiniquodon kalanoro'' *Place: Makay Formation *Country: Madagascar *Age: Ladinian/Carnian (Upper Triassic) This species is known from a mandible (holotype UA 10607). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Chiniquodon」の詳細全文を読む スポンサード リンク
