It has a same mark like the Dododex oh wait it’s Dododex is the terror bird that’s where it got the mark
Terror Bird

Everything else ARK players have to say about the Terror Bird.
On scorched earth, I leveled up player resistance to the highest(keep at lowest on bar) so now not even a terror bird, or anything else can kill me(tried with a dire wolf, totally real) Also, got 3 raptors because of my resistance.
They are har d to get so they live in the volcano
Does anyone else think they should add an 3 meter tall one?
