The Tarija Formation is a Pleistocene-age geologic formation found near Tarija, Bolivia.

Background

Fossils of numerous large herbivorous mammals have been discovered, including toxodonts like Toxodon platensis, glyptodonts, ground sloths, and litopterns such as Macrauchenia patachonica.[1] Numerous carnivorous mammals have been found, including Smilodon populator, Arctotherium tarijense, and Protocyon tarijensis.[2]
