== Taxonomy == Trigodon is placed within the family Toxodontidae, within the suborder Toxodontia. It is considered closest to Paratrigodon. Historically, the genus Adinotherium was suggested to be ancestral to Trigodon, while others claim Nesodon was the direct ancestor to the genus, though neither hypothesis is thought to be true in the modern day.
