Theory Of Trituberculy

Theory proposed by Cope and Osborn to account for the evolution of molar teeth. The proposal held that in the development from simple conical teeth, the molar crowns became tritubercular with the base of the triangle buccal in the mandible and lingual in the maxilla. The simple tritubercular molar then gave way to the more complex molars of placental mammals.
