I found one while trying to find tamable direwolves and hyenaedons and sabertooths. I had seen a giant yuty and flew away and saw a white figure running from a carno. Picked it up and was in shock. Flew it from near blue obelisk to red obelisk. Popped it in a stone trap. Tamed it for an hour with berries. Level 32 male. His name is starlight, and he lives happily with a direwolf, argy, tapejara, three thylas, and more.
