Probainognathus is a genus of meat-eating 'mammal-like reptile', (Therapsids), which lived during the lower Upper Triassic of South America. This creature had an incipient squamosal-dentary jaw-cranium joint, which is a clearly mammalian anatomical feature.
Genus: Probainognathus
Species: Probainognathus jenseni Romer, 1970
Place: Chanares & Ischigualasto Formations
Country: Argentina
Age: Carnian, Upper Triassic
Remarks: Known from about three dozen specimens, this creature was only about 10cm long. Two skulls, including the holotype, were stolen from the University of La Rioja, Argentina, in February 1994. A pair of Probelesodon holotypes, (P. lewisi and P. minor), accompanied them.
