Macrocerus (or "big horn") is one of my earliest designs so I already had how I wanted it to look planned out fairly well in my head. It is a large, slow and heavy herbivore. Like the Aragnodon, it was originally meant to have mandibles that it would use to dig up roots. However, because the animal's head is already heavily armoured, I decided to dispense with the mandibles and, instead, gave it tusks either side of its head. It also had a club on the end of its tail which, again, I got rid of to try and give it a more compact and sturdy appearance.
