I looked up for Scorched Earth specific creatures and deinonychus was there. I don't know if that's true, but if the app is right, then hopefully there will be nests in Scorched Earth as well for or fellow desert survivors as well.
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.
