Ellie: So, what are you working on?
Alan: Raptors mostly.
Ellie: My favorite.
Alan: Do you remember the sounds they made?
Ellie: I try not to.
Alan: Ellie, all our theories about raptors intelligence, what they were capable of, we weren't even close.
Ellie: Tell me.
Alan: Well, we did cranial scans of a fossil skull. We found what looks like a very sophisticated resonating chamber.
Ellie: Wait a second. So we were right. They'd have the ability to vocalize
Alan: I'm convinced it's the key to their social intelligence. Which explains why they could work together as a team. They coordinate their attacks so their prey wouldn't know what was going on.
Ellie: They could talk to each other.
Alan: To a degree we never imagined. Ellie, they were smart. They were smarter than dolphins and whales. They were smarter than primates.
