You need some info on the Futalognkosaurus,

the Baurusuchus, and the Dicynodon, where do you go?

- [Voiceover] Wikipedia.

- [Voiceover] Thanks Nobumichi.

- Oh no problem.

- [Voiceover] How do we know what

these prehistoric creatures looked like?

- Lots of careful research and attention to details.

- [Voiceover] Wait, wait how do you know?

- I draw them.

- [Voiceover] Wait really all of them?

- [Nobumichi] Well, a lot of them.

- [Voiceover] This is Nobumichi Tamura.

- Hello.

- [Voiceover] And he's got a pretty cool day job.

- I'm working at the Advance Light Source

Lawrence Berkeley National Laboratory.

And my job here is to take care of this machine,

the microdefraction and station.

- [Voiceover] The microdefrac, what?

- Microdefraction and station.

- [Voiceover] Ah.

But it's at night and on weekends

that Nobu channels the scientific know-how

into his dinosaur drawings.

- It's called paleoart.

- [Voiceover] My bad.

Paleoart is an original artistic creation

that depicts prehistoric life

according to the latest research.

Right Nobu?

- Exactly.

It's a combination of science and creativity

so I basically read the latest discovery

on prehistoric animals based on that factual data.

This is what I've been doing for the last eight years.

- [Voiceover] And Nobu's got a lot to show for it.

By his estimate he's published over 1,500 drawings,

including some in this book that he co-authored.

But it wasn't always smooth sailing.

The first drawing, that was one of a dinosaur

called Chasmosaurus, but it was taken out

by the editors because it wasn't accurate enough.

- [Voiceover] That's okay Nobu.

Can't bat a thousand.

- Is that a baseball reference?

I'm French.

- [Voiceover] I get it not every baguette can be perfect.

- Why don't you?

- [Voiceover] Wait, wait, wait, come back, come back.

Come back.
