Temporal range: Late Triassic
Jachaleria was a dicynodont herbivore that lived in the Carnian stage of the Upper Triassic, approximately 220 million years ago. Jachaleria was one of the last representatives of the dicynodonts, occurring in Argentina and Brazil. It lacked teeth, much like Stahleckeria, but was closer in size to Dinodontosaurus.
- Jachaleria candelariensis  is found near Candelária City, in the paleorrota geopark in Brazil. It grew to perhaps 3 meters in length and weighed 300 kilograms. Throughout the early part of the Upper Triassic dicynodonts were absent from the paleorrota and the rhynchosaurs were the dominant herbivores. At the end of Carnian, however, the rhynchosaurs became extinct and the dicynodonts appear in their place. Jachaleria candelariensis occurs in the Caturrita Formation.
- Jachaleria colorata is found in Argentina, in the Los Colorados Formation. It is very similar to Jachaleria candelariensis.
