It's April of 1878, near Como Bluff, Wyoming.

Two men are perched on the side of a steep mountain quarry, driving hard at the ground with

pickaxes.

What they find here could put a lot of money in their pockets.

But it's not gold or silver or gems thereafter.

It's bones.

Dinosaur bones.

These men have been hired by a very famous paleontologist, a man named Othneal Charles

Marsh.

Marsh told them, find as many bones as you can.

The bigger the better and ship them back to me, immediately.

But Marsh is also worried.

He says, look out for people stooping around.

He's worried about one man in particular.

His arch rival, another paleontologist named Edward Drinker Cope.

As the light begins to fade, the two men spot something on the horizon.

It's a person lumbering towards them.

The hairs on the back of their arms stand up.

He wears a big coat, walks through the limp, gets closer, closer.

What do you want?

They ask him.

Who are you?
