As you explore Skyrim's various caves and dungeons you'll no doubt notice human skeletons and skulls. Thing is, you won't notice any other variations. A bit odd considering the number of races/beasts in the game. This mod changes all that.
Beast Skeletons adds new, lore-friendly skeletons to the game bringing a bit more variety to Skyrim's dungeons and caves.
As you explore you'll start to notice Argonian, Khajiit, Orc, and Elf bones. They are found in a wide range of locations around the map and you can find the locations on the mod's page on Bethesda's website.
This one is available for Xbox One. It's not available for PlayStation 4 yet.
