Toxodon

Toxodon (meaning "bow tooth") is an extinct genus of South American mammals from the Late Miocene to Middle Holocene epochs (Mayoan to post-Lujanian in the SALMA classification) (about 11.6 million to 5000 years ago).[1] [2]  It is a member of Notoungulata, one of several now extinct orders of hoofed mammals indigenous to South America. It was among the largest and last members of its order, and was probably the most common large-hoofed South American mammal of its time.
