Surprised scientists have discovered the remains of a saber-toothed vegetarian.
Researchers report that the leaf-crunching animal lived 260 million years ago in what is now Brazil. It was about the size of a large dog and had nearly 5-inch long canine teeth.
The research team notes that large saber-shaped canine teeth are unexpected in a plant-eating animal. They say the enormous teeth may have been for self-defense or for battling for territory or females.
The creature is known as Tiarajudens eccentricus (tee-AH-ruh-HOO-denz ek-SIN-trik-us).
The researchers report on their discovery in Friday's edition of the journal Science.
