Toxodontids were endemic South American ungulates, characteristic of the Cenozoic faunas.Although variable in size, their skulls present a conservative morphology. Among them, Adinotheriumovinum is a rather small basal taxon characteristic of the early Miocene Santacrucian Age (SantaCruz Province, Argentina). The primary objective of this contribution is to provide a detailedanatomical description of the endocranial morphology of A. ovinum, an approximation of the brainand associated soft-tissue structures, and considerations about the relative brain size in this species.
