Description
Another astrapothere! Hilarcotherium castanedaii lived in the Middle Miocene, 15.5-11.8 million years ago, in South America (fossils found in Colombia). South America at the time was an 'island continent', disconnected from North America. As a result, a really distinctive kind of wildlife evolved there, kinds found nowhere else. The astrapotheres in ways mimicked tapirs and elephants, though only very distantly related to them. It reached a bodyweight of over a ton. Another species, Hilarcotherium miyou, was estimated at weighing 6.5 tonnes, which would make it the largest astrapothere and one of the largest South American mammals ever.
