The Qurupeco is not to be trifled with.
Even though the Wyven is a stone eating creature, its favorite meal is elephants. Its strong, long legs makes it possible to grab the big animal. It also eats hippos and other big herbivores. If they whip their tail with strong enough speed, they can manage to kill the animal.
The Wyverns like hot and warm places. A good place for a Wyvern to be is in a small desert or in dry grass. Otherwise, they prefer a cliff on a high mountain.
