Fact: Hyaenodons in real life were actually not even related to hyenas , their closest living relatives are pangolins(which also are not related in the slightest to raccoons, anteaters, aardvarks, armadillos or hedgehogs). And real hyenas despite appearances are actually not related to dogs or wolves, in fact their closest relatives are meerkats and mongooses and meerkats and mongooses' closest other relatives are cats and civets(also known as bearcats)

You can find them in the city on extinction

They can jump through stone windows. If you have any Windies in your taming pen, close them before you grab these guys.

Hyaenodons are opprotunists, meaning if they have an opprotunity to get a quick, free meal, they'll take it. Corpses? Heck yeah. Low HP? Yup.

I haven’t found a single one in mobile!

You can find these cute little guys on beaches near the snow.

They will attack you if they are in large numbers. If they attack, don't flee. Just keep fighting, because when they get to 2 (or 3) they will flee. They are also way to fast to flee form. Just stand and fight. (You're screwed without a mount)

You Can Find them near the snow biome there between both borders and won't attack unless the feel like they can take you on so if there's 6 in a pack there's going to attack and alpha cannot be tammed
