Mammal
Toxodon platensis
Toxodon platensisToxodon platensis was a massive, barrel-chested herbivore that combined the ponderous build of a rhinoceros with elevated eyes and nostrils suited for browsing near water. Herds grazed across the open grasslands and wetland margins of South America, using ever-growing incisors to clip tough grasses and submerged vegetation. First unearthed by Charles Darwin during the Beagle expedition, its fossils helped illuminate an entire native lineage that flourished for millions of years before vanishing at the end of the Pleistocene.
