And it wasn't more than an hour when someone came running up to me and said, you got to come and see this.

The snout is coming out of the ground.

It's our skull.

And then another hour or two, when another team member brushed against a bone that was sticking out of the ground and comes up, what do you think this is?

And it's the crest of this dinosaur.

We knew we had a new species.

This is often the part of the skull that really varies, and there was absolutely no question about it.

We had...

put together that skull from all new pieces, drawings of the bones that were destroyed, etc.

And it's low and long like an alligator, but this one takes the cake.

It's even longer.

But then sweeping off the top of the skull is this crest.

It looks like a scimitar.

We call it a scimitar-crested dinosaur.

Our analysis of the dinosaur is something like a hell heron, something that waited and ambushed and would grab anything that came close, even if it was on land.

It was 40 feet long.

It didn't care.

It signaled its mates.

It threatened its rivals with its crest and with its claws and jaws.

And it was a poor swimmer and a non-existent diver, just like a blue heron.
