Brasilodon ("Brazil tooth") is an extinct genus of cynodont that lived during the Norian age of the Late Triassic Period, about 228 to 208.5 million years ago. The average length of Brasilodon is approximately 12 cm and weighed about 20 grams.The average size of this cynodont species is about the size of extant mice. Brasilodontids are most likely insectivores due to their teeth. The two species in this genus are B. tetragonus and B. quadrangularis, two very small cynodonts belonging to the family Brasilodontidae.
