If you’re new-ish you probably have a raptor used for traveling. But DO NOT try to fight these things with a raptor they are faster they stack bleed and they are faster than a raptor.if you want to escape try to run past other wild Dino’s to get them to get angry at the wild Dino your running past then when they leave you alone get the hell out of there... FAST!!!
I was sitting on a flyer on a cliff above the deinos, thought I was safe to wait for my moment to steal their eggs...had the biggest heart attack when one of them decided to climb up the cliff. I accidentally dismounted in shock and fell right into the packs claws, where they shredded me to death. Don't be scared of them, they smell it.
