There is a Nest near beach 2 that is alone and you can lure deinonychus off a cliff then steal the eggs easily on a ptero Note: most of the time you don't need to lure them off the deinonychus/s there are 9/10 times distracted by a wild Dino
If you have some pack of 4-5 raptors as bodyguards, is easy to search for Deinonychus’ nests and take their eggs without having a fly mount. In case of some Deinos attacks you, your bodyguard can kill the easily.
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.
