All our theories about raptor intelligence, what they were capable of, we weren't even close.

Tell me.

Well, we did cranium scans of a fossil skull. We found what looks like a very sophisticated resonating chamber.

Wait a second? So we were right. They had the ability to vocalize.

I'm convinced that's the key to their social intelligence.

Which explains why they could work together as a team.

And coordinate their attacks so the prey wouldn't know what was going on.

They could talk to each other.

To a degree we never imagined. Ellie, they were smart. They were smarter than dolphins or whales. They were smarter than primates.
