"Toxodon" was among the few notoungulates to survive the Great American Interchange, and is presumed to have died out due to human predation and/or climatic changes during the Pleistocene. Its fossils were first studied by Charles Darwin on his voyage on the "Beagle". It is speculated that these animals lived very much like hippopotamuses in South America, and were almost certainly hunted by "Smilodon populator".

"T. platensis" was a large squat herbivore (about 2.75 m (9 feet) long, 1.5 m (5 feet) high and 1,5 tons), with the general appearance of a rhinoceros.
