Despite appearances, Andersarchus is not related to modern scavengers, like dogs or hyenas. Bizarrely, he has hoofs on his feet instead of claws. In fact, his nearest modern relatives are hoofed animals, like sheep and goats.

Andrewsarchus was a huge, carnivorous mammal that was initially thought as a Mesonychid, but is no longer classified as so. It was as tall as a horse and weighing close to a ton, featured in the second episode of Walking with Beasts.


Andrewsarchus was a meat-eater and a scavenger that despite their appearances, were not related to modern scavengers like coyotes dogs, wolves, or even hyenas. Bizarrely, they had hooves on their feet instead of claws. In fact, their nearest modern relatives are hoofed animals like sheep and goats,

It is natural behavior for an Andrewsarchus to search for carrion on beaches.

as they were related to modern day ungulates (hoofed mammals) on one hand, and to cetaceans (whales and dolphins) on the other. They are, in a sense, sheep in wolf's clothing. Roy Chapman Andrews discovered in the 1920's in Mongolia and it got named after himself (AndrewsarchusmeansAndrews' beast). Andrewsarchuslived in Mongolia in the late Eocene, from 40 to 35 MYA. At about 5.5 meters long, 2 meters tall and weighting 1 tonne, Andrewsarchus was the largest land mammalian carnivore ever to walk on the Earth.
