C. theotonicusChiniquodon is a genus of carnivorous "mammal-like reptile", (Therapsid), which lived during the lower Upper Triassic in South America. These animals were up to the size of a dog. This genus seems to be most closely related to a contemporary genus, Probelesodon. In various respects, the anatomy is very mammal-like, though not strongly enough to be viewed as a direct ancestor.
Other contemporaries included early dinosaurs. As both groups filled a similar ecological niche, this might explain the disappearance of fairly large hunters such as Chiniquodon.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[1]
- Place: Ischigualasto Formation
- Country: Argentina
- Age: Carnian (Upper Triassic)
This skull was reassigned to this genus in 2002.[2] 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[3]
- Place: Makay Formation
- Country: Madagascar
- Age: Ladinian/Carnian (Upper Triassic)
This species is known from a mandible (holotype UA 10607).
