[MUSIC PLAYING]

So do you know what dinosaur this is from?

ALLISON: I don't.

It was my grandfather's.

I have no idea.

I just know that it's a dinosaur bone.

It's a big dinosaur.

[LAUGHS]

Yes.

I'm here at the pawn shop today to sell

my grandfather's dinosaur bone.

He's had art all over his house, and this is one of the things

that was displayed.

I'm not even sure if it's just a piece of art,

or if it's a real dinosaur bone.

If I'm able to make a deal, I'm getting a mommy makeover

and going to Hawaii.

RICK: I am just, like, baffled.

To find something this big and intact is incredible.

In the 1800s, they realized that, hey,

there was really big animals walking

around the planet at one time.

And soon after, archaeologists started

racing to excavate whatever fossils they could find.

There were certain deposits in the United States

where there's just massive amounts of them.

ALLISON: Right.

RICK: So how much do you want for this thing?

I was think $40,000.

$40,000.

'Cause it's pretty old.

OK.

We don't even know what kind of dinosaur it's from.

I also know that a lot of times, they'll

find, say, this bone right here and cast the rest of it

in plaster.

So a lot of times, these dinosaur bones

are not all complete.

Sometimes only, you know, that might be real dinosaur.

ALLISON: Uh-oh.

OK.

I'm gonna put that back for you.

[LAUGHTER]

OK.

There we go.

Put his toe back.

Put his toe back.

[LAUGHS]

So, like, let me get someone down here

to see if the entire thing is real,

and he should be able to tell us the dinosaur's name.

ALLISON: Oh.

That would be great.

Yeah.

It was Bob the dinosaur.

Right. [LAUGHS]

So give me a few minutes.

I'm gonna give this guy a call, and I'm

gonna get him down here, and we'll get this figured out.

ALLISON: Perfect.

Just goes to prove, you never know what's

gonna walk through that door.

[LAUGHS] Right.

I'm totally happy with an expert coming in.

I'm really excited to see if it's real and what it's worth.

RICK: So there it is.

Wow.

I think it's real. [LAUGHS]

Hi.

How are you?

Hi.

RICK: All I know is it's a dinosaur leg.

This is a Camarasaurus.

Camarasaurus was a long-necked dinosaur that

lived in the Jurassic period.

It's a quadrapedal dinosaur--

walked on four legs.

OK.

ANDRE LUJAN: To authenticate, we'll take a look at this

to see if there's any cast pieces.

Weight is going to be the first indicator.

That definitely feels like a cast toe.

RICK: OK.

ANDRE LUJAN: That's not that big a deal.

Looks like these little toes--

well there, we're starting to get into some real bones.

These metacarpals-- these are real.

RICK: All right.

ANDRE LUJAN: If it were cast, this would be much lighter,

so that's great.

The real value is in the real bones--

the humerus, the radius, and the ulna.

That's where the meat of the piece is.

This is kind of the details.

All right.

The dead giveaway is gonna be if we

can see any cell structure.

I'm gonna come around this side, Rick.

All right.

You see the black and white difference there?

RICK: Uh-huh.

ANDRE LUJAN: That looks like calcite that's

in-filled the bone cells.

So this bone-- this is definitely real.

RICK: OK.

Take a look at the humerus.

Look at that.

You see that cell structure in there?

Yeah.

Yeah, this bone is definitely legit.

RICK: OK.

So the big question-- what did these things go for?

If this thing came into my museum,

I'd be very comfortable appraising it at 25,000.

RICK: Well, thanks again, man.

I really appreciate it.

Thank you.

RICK: So what do you think of that?

So I am pleased that it's--

for the majority of it is authentic.

I mean, what will you take for it?

So what about 21,000?

I'll give you 15 grand for it.

How about 20?

I'll tell you what, I'll give you 18,000, not a penny more.

That's-- that's my top dollar.

Sold.

RICK: Sweet.

I will meet you right over there,

and we'll do some paperwork.

Thank you.

I just bought a dinosaur leg.

Guess there's a first for everything.
