My friend and I were attacked by 1 Rex, 2 Carnos, and an Argy. They attacked from different directions at the same time. We are playing on Valguerro and our base is on a sandbar in the water, so there shouldn't have been an aggro issue.

They only thing I can think of, is we stole a Pelagornis and Carbo egg from a nest there on the beach. We killed the "parents" so there was no danger. Afterward, we were just doing our own thing at the base and then boom....attack by all different dinos that only cared about us. Is there something weird with eggs? like moving them to a p-bin etc.?

What did we do wrong? how do I prevent it?
