>> hello, folks. It's me, the conductor. Today, big
Dinosaur week continues with a visit to our friend the
Argentinosaurus.
So come on along with me on the dinosaur train.
All aboard!

>> tickets, tickets, please.
Well, hello, pteranodon family.
>> hello, mr. Conductor!
>> argentinosaurus acres, huh♪
Visiting your friend arnie♪
Must still be big dinosaur week.
>> yep! This whole week we've been riding all around the
Mesozoic era, meeting some of the biggest dinosaurs.
>> and we saved the biggest one that we know for last.
>> indeed. Argentinosaurus is certainly one of the biggest
Dinosaurs that I know.
>> awk! And you know a lot.
>> look how much bigger it is than a pteranodon.
>> right, and with 4 legs and a long neck, argentinosaurus is
A...
>> sauropod!
>> bingo! All sauropods have the following things in
Common--giant bodies, long necks...
>> and tiny heads! Well, at least compared to their huge
Bodies!
>> well said, miss tiny. What else did you learn this week♪
>> well, sauropods have to eat a lot of plants to get enough
Energy to keep their huge bodies going.
>> and growing. In arnie's case, he's already big, but by
The time he's grownup, arnie will be longer than a couple of
These passenger coaches.
>> whoa!
>> can you believe it♪ Arnie's already too big to ride the
Dinosaur train.
>> I know. It's so sad.
>> when we visit today if we talk about the train, we might
Make arnie feel bad.
>> you're right, buddy, so let's remember not to talk
About it.
>> awk! I'm proud of you two for thinking about arnie's
Feelings.
>> I agree, mrs. P. Your kids are so thoughtful all the time.
Time♪ Time♪ ! Ooh. Time tunnel approaching! Next stop:
Argentinosaurus acres in another part of the cretaceous
Time period.
So long, pteranodons and t. Rex. Have fun with arnie.
>> bye!
>> ok. Let's go find arnie!
>> tiny, I think he's right behinds us.
>> shh.
>> boo! Ha ha ha!
>> hi, buddy. Hi, tiny. I wanted to surprise you by
Hiding behind the station, but I think I'm getting too big to
Hide behind it anymore.
>> I know. Your head sticks out one end, and your tail sticks
Out the other.
>> I think you're even bigger than the last time we saw you,
Arnie.
>> yup. I'm still a-growing.
Pretty soon, I won't be able to hide behind anything.
>> no more hide-and-seek♪
>> nope, but there are good things about being this big,
Too. When we're full grown, argentinosaurus don't have any
Predators.
>> you mean, big meat-eating carnivores that want to eat you♪
>> right! They don't even bother trying to eat us.
>> wow! That's amazing!
>> but while you're still a kid, you stay near one of your
Parents, right, arnie♪
>> right. There's dad right over there. Hi, dad!
>> hey, hey, arnie! Oh. Hi, pteranodon family.
>> hello, mr. Argentinosaurus.
So good to see you.
>> wow! I can see why predators don't even bother trying to eat
A full-size argentinosaurus.
They're huge!
>> yup. No one's gonna bother us. Ha! We're just too big.
>> [growls] nah.
>> awk! But, you know, even for a kid, arnie's huge, too.
>> yup. I'm already way too big to ride the train anymore, but
I still like to hang around by the station. Don't you just
Love the dinosaur train♪
>> um...Yeah.
>> [sighs] yeah. I remember when I was
Small enough to ride it. I just love that old train.
♪ I love the tender I love the brakes
I love the sound that the drivers make
>> I love the gauges I love the pump
>> everything about it makes me want to jump
On a train ♪ >> [sighs]
>> we just love trains.
You guys are so lucky that you can still ride it.
>> well, sure. It's fun, but, hey, do you want to play
Something, a game♪
>> hmm. Uh, we could play hide-and-seek.
>> uh, hide-and-seek♪
>> yeah. In those woods over there. You guys are small
Enough to try and hide from me.
Heh. Come on.
>> say, we'll all go. You kids want a ride on my head♪
>> yeah!
>> whoa, whoa, whoa! Ha ha ha!
>> ok. You guys hide behind the trees, and I'll use my long
Neck to try to find you.
>> great! Close your eyes and count to 10.
>> whoo-hoo!
>> 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. Ready or not, here I come.
>> ha ha ha!
>> heh heh. I see you, buddy.
>> ha ha! Good one.
>> awk!
>> tiny♪
>> psst.
Ha ha ha!
Ahem.
Boo! Ha ha ha! That was funny!
>> got you.
>> ok. Now what should we play♪
>> let's pretend that we live in a big cave. That's what it's
Like down here under arnie's dad.
>> great.
>> uh, do you guys mind if we walk back to the train station♪
>> why♪
>> my dad and I just like to hang out there in the afternoon
And wait for the train to come by.
>> yep. We just love to hear that old whistle blow.
>> it's our favorite sound.
>> come on. Race you to the station, arnie. Buddy and tiny,
Want a ride♪
>> yeah♪
[booming] >> here we are. Slide down,
Kids.
>> oh, oh, oh, whoa!
>> whoa, whoa, whoa! Ha ha ha!
[train whistle blows] >> oh, I think I hear it. There
It is.
>> the dinosaur train!
>> hooray!
>> all right!
>> whoo-whoo!
>> hello, dinosaur train fans.
>> hello, mr. Conductor!
>> how's the train running today♪
>> like a well-oiled machine, right on schedule. Ooh. And
Speaking of which, we'd better stay on schedule. All aboard!
>> arnie, mr. Argentinosaurus, it was such a nice visit.
>> wish we could come with you.
Ha ha ha!
>> ha ha ha!
>> but we're too big! Ha ha!
Bye!
>> bye!
>> aw. Why the long faces, buddy and tiny♪
>> aw. Mr. Conductor, it's just so sad that our argentinosaurus
Friends are too big to ride the train.
>> yeah. We're sad for arnie and for all the giant sauropods
We've met this week.
>> aw. I know, kids. I wish there was something I could do
About it, but they're just too big. Oops! Better call it. Time
Tunnel! Time tunnel approaching!
Next stop, troodon town in another part of the cretaceous
Time period.
We're taking the train into the roundhouse to switch out some
Cars. Care to come along and watch♪
>> yes!
>> come on, kids! Awk!
>> [groaning] >> oh! This is exciting, isn't
It, kids♪
>> yeah! So many different cars for different kinds of jobs,
The aqua car for sea creatures.
>> what's that big flat car for♪
>> that's actually what it's called, tiny, the flat car.
>> they put piles of branches on it for the biggest
Herbivores to eat.
>> ohh! Come on, everybody! Mr.
Conductor, I just got a great idea! You know we wish that
Arnie and the other big sauropods could ride the train,
Right♪
>> well, sure, tiny, but you know they are too big to fit in
The cars.
>> whoa! You mean they could ride on the flat car♪
>> hmm. You know, tiny, maybe we could actually do it.
>> [all talking at once] >> just imagine. What if all
The biggest dinosaurs could ride the train♪ That would be
So fantastic!
>> it is called the dinosaur train after all. We should be
Able to haul every kind of dinosaur!
>> oh, it's a crazy idea, but as long as it's safe, we can
Probably make it work.
>> what if we built a guard rail around the outside of it♪
>> and then they could duck down when we go through the
Time tunnels.
>> you know, it just might work.
>> all right. Get over there.
Make sure it's safe.
[train whistle blows] ahem. Argentinosaurus family,
May I present the latest specialized car from
Dinosaur train industries, the sauropod flat car.
>> ooh! You mean, I get to ride the dinosaur train♪
>> all aboard!
>> whoa!
>> dad, do you want to ride the train first♪
>> no, son. I want you to ride it first.
>> wow! Thanks, dad.
>> come on, arnie. Buddy and I can ride in the observation car
So we can be right next to you.
>> ha ha! This is so great.
>> where do you want to travel to first, arnie♪
>> ooh, ooh! Pteranodon terrace. I've always wanted to
See your nest and the western interior sea.
>> we'd love to have you, arnie. We'll take good care of
Him, mr. Argentinosaurus.
>> and the dinosaur train will have him back here in time for
Dinner. All aboard!
[whistle blows] >> bye, dad!
>> bye, arnie! Have a great time.
>> bye!
>> ♪ the biggest dinosaurs the biggest dinosaurs
The biggest dinosaurs the biggest dinosaurs ♪
Whoo-hoo!
>> hi. I'm dr. Scott, the paleontologist. Hey, guys. I'm
Down here. This dinosaur is so big, you can barely see me. Do
You know what kind of dinosaur this is♪
>> argentinosaurus.
>> that's right, this is an argentinosaurus, one of the
Largest animals ever to live on
Land. Now, what's the biggest animal living on land today♪
>> an elephant.
>> right. Elephants are big, but argentinosaurus was about
100 feet long. That's as long as 5 elephants put together. An
Argentinosaurus weighed about as much as 20 elephants. Now,
That's a lot of dinosaur. And just like elephants do today,
Argentinosaurus must have eaten an amazing amount of plant
Food. Paleontologists still wonder how argentinosaurus
Could have eaten enough food with such a small head. Now,
How do elephants reach high up into trees to find food♪
>> with their trunks.
>> argentinosaurus didn't have a trunk, but it did have a long
Neck that it probably used to reach high into trees. And
Being such a gigantic animal, it probably spent most of the
Day just trying to find enough of the green stuff to keep
Itself going. Ok, remember, get outside, get into nature, and
Make your own discoveries.
>> hello, folks. It's me, the conductor. Today the pteranodon
Family visits a geyser. That's a hole in the ground that
Shoots steam and hot water into the sky. So come on along with
Me on the dinosaur train. All aboard!
[whistle blows] tickets. Tickets, please. Well,
Hello, pteranodon and lambeosaurus families.
>> hello, mr. Conductor.
>> where are you all off to today♪
>> to geyser gulch station.
>> ooh! Geyser gulch, huh♪
>> yep. None of us have ever seen a geyser before.
>> we have so many questions.
>> well, that's what I like to see, kids getting out into
Nature and asking lots of questions.
>> dad told us it's a place with lots of amazing holes.
I love holes.
>> well, you are in for a treat, don, because there's
Lots of holes at geyser gulch.
But you have to be careful around these holes.
>> why♪
>> dad told us that the holes have a surprise.
What kind of surprise♪
>> the surprise comes from inside the holes. A geyser is a
Natural fountain that shoots super-hot water and steam way
Up into the sky.
>> but why does the hot water shoot out of the holes♪
>> good question, tiny. Why do you think the water shoots out♪
>> hmm. Maybe the water is like me. It just likes to jump out
Of holes and surprise everyone.
>> hmm. Interesting hypothesis, don. Heh! Now, take a gander at
This. The inside of the earth is so hot, it even melts rock.
And when the melted rock called magma gets close to the
Surface, it warms up the water that's under the ground. When
That underground water gets really hot, the pressure grows
And grows until the super-heated water explodes up
Into the air through holes and cracks. That's what we call a
Geyser. They shoot way up in the air. Some go over 100 feet
High.
>> wow!
>> whoo!
>> I can't wait to get there and see these geysers for
Ourselves.
>> heh heh. And we dads can't wait to show them to you,
Right, larry♪
>> abso-positvely-tutely, mr.
P. Heh heh heh!
>> and where there's hot water coming out of the ground, you
Can also find what we call hot springs.
>> hot springs♪
>> ooh, hot springs♪
>> yep. There are pools of warm and hot water that form near
The geysers. But again, the water can get quite hot. So you
Kids should only get in the pools with your parents'
Permission.
>> yeah, right, right, but let's get back to those geysers!
>> that shoot out of those super holes.
>> [cheering] >> ooh. I've been to these hot
Springs before, mrs.
Pteranodon. They are simply amazing. Some are hot, some are
Warm, some are cool. You just find the one with the perfect
Temperature and hop in. You will love them.
>> this'll be perfect. We can relax in the pools while the
Dads and the kids watch the geysers.
>> it's gonna be great.
>> next stop, geyser gulch.
Geyser gulch station!
>> [cheering] >> have fun at the geysers, and
Remember, you never know when hot water will shoot up in the
Air. You have to wait and watch. So be careful around
Those holes, especially you, mr. The don.
>> ok, mr. The conductor.
>> we will, mr. Conductor! Bye!
>> whoo-hoo!
>> heh heh heh!
>> oh. It's been forever since I've been in those pools. I
Surely would love to walk down to the pools and soak my toe
Claws in that bubbly water. But I'm the conductor. I can't. Got
To stay with the train. Ooh, maybe I should.
>> well, maybe you should!
>> mother!
Must you come sneaking up on me like that♪
>> I can't help it. Troodons are stealthy. Ooh, I heard you
Talking to yourself, and I thought you were talking to me.
Ha ha ha! And I say, why not go down to the pools♪ Take the
Afternoon off. I can fill in for you as conductor. Haven't
Forgotten how to do it. Ha ha ha!
>> why not♪ I deserve an afternoon off from the dinosaur
Train once in a while. I got my own special pool that no one
Else knows about. I'll go there, and no one'll be the
Wiser. Thanks, mom!
>> have a great time at your secret pool, sonny boy.
>> wow!
>> [whistles] all right, team pteranodon
And team lambeosaurus, let's stick together and find us a
Geyser!
>> [cheering] >> you dads go ahead and take
The kids to the geysers. Mrs.
Pteranodon and I are gonna find the hot springs.
>> ooh. Ok, lorraine. See you in a bit. Let's go, let's go,
Let's go!
>> all right, larry, but let's all be careful. Remember,
Geysers can shoot hot water up at any time.
>> look, dad. There's a bunch of dinosaurs standing around
That one big hole. I wonder if that's the geyser.
>> let's go see.
>> morris stegosaurus♪
>> oh. Hey, small ones. What's up♪
>> what are you doing here in the cretaceous♪
>> yeah. You're from the jurassic time period.
>> just visiting. I time-traveled here. I'm a big
Fan of geysers, tiny. All these dinosaurs are. We're hanging
Out here waiting for old reliable to erupt.
>> old reliable♪
>> yeah. It goes off pretty often--several times a day,
Too. I mean, it's not like you can tell the time by it, but
It's pretty reliable. That's why they call it old reliable.
>> ooh. So when it's gonna erupt♪
>> well, you just have to wait and be patient. Actually, the
Waiting is almost the best part, right♪ Just being here
Now.
>> being here now. I can do that. Look at me. I'm being
Here now.
>> ooh!
>> oh, oh, oh, oh.
>> so when's it going to erupt♪
>> you just have to be patient, shiny. We're being here later.
Wait, that's not right. We're...
>> [cheering] >> ooh! Here they are--the
Pools.
>> oh, they're beautiful.
And what a lovely spot. But how do we know if the water's
Too hot♪
>> you just dip your toe in very carefully, like this.
Ooh. Ooh.
Too hot. Not this one. Hmm.
Uh...Nope. Too cold.
Hmm.
>> rawk! Lorraine, I found one that's perfect!
>> ooh! Wonderful. Let's hop in.
>> rawk! It's heavenly.
>> [sighing] >> [humming]
>> ooh.
>> huh♪ Huh. I must be hearing things.
Ahh. Just rest my eyes for a minute. Got to stay on
Schedule. Time tunnel. Time tunnel approaching...
>> [cheering] >> ok, that was great. Now what
Do we do♪
>> well, we are out in nature.
Let's go exploring, because we're the...
>> nature trackers! Whoo-hoo!
>> hey! I see those pools the conductor was talking about.
They have steam coming off of them.
>> rawk! They're beautiful.
>> come on, you guys!
>> ok! Wait up, nature trackers. We'll come, too.
>> yeah!
>> let's go! Come on!
>> ooh. This one's warm. Yike!
Ho, that one's too hot, kids.
>> aw, mine's cold. Warm.
Warmish.
>> hmm. Too cold.
Mmm. Too hot.
Rawk! Just right.
>> just right, eh♪ Let's see.
>> you know, she is right.
>> last one in's a rotten dinosaur egg!
>> ya ha ha!
>> [sighing] >> oh, yeah. Kids, larry and I
Are gonna soak in this pool for a minute. So all of you
Remember to stay within rawking distance.
>> and hooting distance.
>> yeah, come on, go to this one.
>> [squawking] >> huh. Too many dinosaurs at
The hot springs nowadays.
Tourists, hootin' and tootin'.
>> [laughter] >> aah! Giant dinosaur attack!
>> ooh!
>> oh, my. Oh, my. Oh, my.
>> mrs. Pteranodon. Mrs.
Lambeosaurus. I'm terribly sorry to disturb you. See, I
Was just attacked by a giant dinosaur, and I--
>> [laughter] >> ohh, it was just the kids.
>> oh, mr. Conductor.
>> oh, gosh! And me wearing nothing but my bathing hat.
This is so embarrassing. Kids, could you please bring my
Clothes from the other pool♪
>> sure, mr. Conductor.
>> awk! We'll be right back.
>> w-w-we heard the shouting.
Is everyone all right♪
>> is everyone all right♪ Looks like everyone's having the best
Time ever! How's the water, kids♪
>> fantastic!
>> whoa, ho, ho. Well, wait until you see the secret pool
We just found on the other side of that boulder. It's the best
Pool ever.
>> b-b-but that's my secret pool.
>> ha ha ha! I'd say the secret's out, mr. Conductor.
Come on, everybody!
>> [cheering] >> rawk! Just right.
>> come on in, mr. Conductor!
>> ohh. Pteranodon!
>> [cheering] >> rawk! There's the dinosaur
Train. Time to head back, kids.
>> is it♪ Oh. Where'd I put my watch♪
Well, old reliable should be going off again.
>> [gasping] [cheering]
[whistle blows] >> the engineer must be getting
Real impatient to get going.
>> ho ho, they're fine. Mother won't let them leave without me.
>> [laughter] >> ha ha ha! You know, it's
Amazing how a good soak in the geyser gulch hot springs does a
Body a world of good. Ahh. I'll probably feel relaxed for weeks.
Whoa!
>> glad you finally made it, sonny. There's tickets to punch
And a lost wallet. Oh, and the toilet's plugged up in the
Passenger coach bathroom. Chop, chop! Let's go! All aboard!
>> oh, mother. As I've said before, that is my line. Oh,
Well. All aboard!
[whistle blows] >> yeah!
>> hi there. I'm dr. Scott the paleontologist. Geysers are an
Amazing feature of nature. They were around during the age of
Dinosaurs, and there's lots of geysers today, too. But what is
A geyser♪ To find the answer, we have to look way down deep
Inside the earth, where the rock is so hot that it becomes
Liquid or molten. When that molten rock rises close to the
Surface, it heats water until it becomes boiling hot. Then it
Erupts out of the earth, and that's a geyser. There are
About a thousand geysers around the world today, and about half
Of them are found in wyoming, in beautiful yellowstone
National park. Check out these yellowstone geysers. Here's old
Faithful, the most famous geyser in the world. About
Every 90 minutes, old faithful shoots water around 150 feet in
The air, and steamboat geyser shoots more than 300 feet into
The air. Ok, remember, get outside, get into nature, and
Make your own discoveries.
>> we love playing games!
>> like all aboard!
>> you can play, too, online at pbskids.Org!
>> and lots of other games!
>> there's so much to learn about all kinds of dinosaurs!
