>> YOU KNOW WHAT'S FUNNY?

THREE OF THE FIRST 4 DINOSAURS IN THE SONG ARE ON-BOARD THE TRAIN RIGHT NOW--THE ONES FOR "B," "C," AND "D." >> YOU'RE RIGHT, BUDDY.

THERE'S THE "B"--NED.

>> "B" IS FOR BRACHIOSAURUS.

HI.

>> THERE'S MR. CORYTHOSAURUS, SITTING IN THE BACK.

>> "C" IS FOR CORYTHOSAURUS.

>> I SAW DEREK IN THE DINING CAR.

>> WHOO HOO!

"D" IS FOR DEINONYCHUS.

>> IT'S TOO BAD WE DON'T HAVE THE "A" ON-BOARD.

THAT'S APATOSAURUS.

[BELL CHIMES] >> WHOOPS!

ANOTHER STOP COMING UP.

AND WOULDN'T YOU KNOW, TINY?

IT'S APATOSAURUS ACRES.

>> [BOTH GASP] >> NEXT STOP, APATOSAURUS ACRES IN THE JURASSIC TIME PERIOD.

[STEAM HISSES] >> BUDDY, THE APATOSAURUS IS GETTING ON THE TRAIN.

YOU REALIZE WHAT THIS MEANS?

>> YEAH.

WE'RE GONNA HAVE THE LETTERS "A," "B," "C," AND "D" ON-BOARD.

>> BUDDY, MOM, I JUST GOT A REALLY BIG IDEA.

>> WHAT?

>> WOULDN'T IT BE GREAT IF WE GOT EVERY DINOSAUR SPECIES IN THE "A TO Z" SONG TO RIDE TOGETHER ON THE DINOSAUR TRAIN?

>> WHOA, AND SING THE SONG TOGETHER?

>> MOM!

CAN WE ASK THE CONDUCTOR?

>> WELL, IT CERTAINLY IS A BIG IDEA.

I'M NOT SURE IF THE CONDUCTOR COULD DO IT, BUT WE CAN ASK.

>> AND SINCE WE'VE ALREADY GOT THE FIRST 4 LETTERS ON-BOARD, WHY NOT PICK UP THE REST OF THE SPECIES?

>> HUH.

OF ALL 26 LETTERS IN THE ALPHABET?

OOH, THAT'S A WHOLE LOT OF DINOSAURS.

>> WE COULD COLLECT THEM ALL.

THE DINOSAUR TRAIN IS HUGE.

IT COULD HOLD 26 SPECIES.

I KNOW IT COULD.

>> AND THEN WE COULD ALL RIDE TO TROODON TOWN AND HAVE A PICNIC AND SING THE "A TO Z" SONG.

>> WELL--HEH!--I LOVE TROODON TOWN.

HEH!

AND I LOVE PICNICS.

>> DOESN'T THAT SOUND FANTASTIC, MR.

CONDUCTOR?

>> WELL, YES, BUT ALL THOSE SPECIES, AND THEY COME FROM DIFFERENT TIME PERIODS, MILLIONS OF YEARS APART.

>> BUT ISN'T THAT WHAT THE DINOSAUR TRAIN'S ALL ABOUT, TRAVELING AROUND THE WHOLE MESOZOIC ERA?

>> WELL--HEH HEH!--YES, BUT MAKING SURE WE HAVE ENOUGH FOOD IN THE DINING CAR AND, OH, I'D HAVE TO REDO TODAY'S TRAIN SCHEDULE.

I JUST-- >> BUT WE'LL BE MEETING NEW CREATURES.

>> AND COMPARING ALL THEIR FEATURES.

YOU KNOW, LIKE TEETH AND TAILS.

>> TRUE, THAT IS WHAT MAKES THE DINOSAUR TRAIN SO SPECIAL, BUT EVEN IF WE DO TRY TO PICK UP ALL THE A-TO-Z DINOSAURS, WE'D STILL HAVE REGULAR PASSENGERS TO PICK UP AND DROP OFF.

>> UH, YOU ARE GOING TO DROP ME OFF, RIGHT?

I HAVE A SPECIAL DINNER PLANNED WITH 300 OF MY COUSINS.

>> YES, MR. STYGIMOLOCH.

WE'LL STOP AT YOUR STATION.

>> HEY, LOOK!

WE'RE REALLY CLOSE TO EINIOSAURUS ACRES, AND "E" IS THE NEXT LETTER IN THE ALPHABET AND IN THE SONG.

>> GREAT!

A QUICK STOP, WE'LL PICK UP JACK EINIOSAURUS, THEN WE'D HAVE "A," "B," "C," "D," AND "E." >> OH, GOSH, TINY.

I'D LOVE TO, REALLY, BUT I PRIDE MYSELF ON STAYING ON SCHEDULE.

>> WE'RE OUT OF LEAVES.

CAN WE STOP AND GET MORE?

>> UM, MR.

CONDUCTOR, WHAT DID YOU SAY THE NEXT STOP WAS?

>> RIGHTY-O.

WE'LL STOP AT EINIOSAURUS ACRES, THEN.

>> YEAH!

LET'S GO!

>> AFTER ALL, EINIOSAURUS STARTS WITH "E." HEH!

TIME TUNNEL!

TIME TUNNEL APPROACHING!

[TRAIN BELL RINGING] NEXT STOP, EINIOSAURUS ACRES IN THE CRETACEOUS TIME PERIOD.

>> JACK?

JACK EINIOSAURUS?

>> YEAH?

WHO'S CALLING?

AH!

IT'S TINY PTERANODON, RIGHT?

AND BUDDY TYRANNOSAURUS.

>> YEAH.

HI.

>> MR. EINIOSAURUS, I WONDER HOW BUSY YOU ARE THIS AFTERNOON.

>> AH, JUST THE USUAL.

YOU KNOW, GRAZING.

AND WHAT CAN I DO FOR YOU?

>> [BOTH TALKING AT ONCE] >> ...AND THEN WE'RE GONNA HAVE A PICNIC.

>> ALL RIGHT.

OH, I LOVE PICNICS, AND I'M THE LETTER "E." EXCELLENT!

LET'S GET ON-BOARD.

[TRAIN WHISTLE BLOWS] I MEAN, IMAGINE, THE SIGHT OF ALL 26 SPECIES IN THE SONG, ALL OF US, SINGING IT TOGETHER IN TROODON TOWN.

WHAT AN ADVENTURE!

>> WELL, YEAH, I LIKE AN ADVENTURE.

I'M JUST TRYING TO MAKE IT WORK.

>> WELL, SURE YOU ARE, AND WE'LL HELP.

WHAT LETTER'S NEXT?

>> "F." FABROSAURUS.

>> DO YOU KNOW ANY FABROSAURUS, MR.

CONDUCTOR?

>> ACTUALLY, I DO KNOW A FABROSAURUS NAMED FANNY.

>> WOW.

IT'S LIKE MR.

CONDUCTOR KNOWS EVERY SINGLE DINOSAUR IN THE MESOZOIC.

>> [CHUCKLES] WELL, NOT REALLY, TINY.

HEH!

JUST SEVERAL THOUSAND SPECIES, AND SOME OF THEM ARE JUST MERELY ACQUAINTANCES.

FOLLOW ME, JUNIOR CONDUCTORS.

>> YEAH!

WHOO HOO!

>> FABROSAURUS IS A SMALL HERBIVORE FROM THE EARLY JURASSIC, WITH SHORT ARMS AND A HORN-COVERED BEAK.

BUT TO GET TO HER, WELL, WE'VE GOT TO GO BACK TO THE JURASSIC.

OH.

>> IT PROBABLY WOULDN'T TAKE VERY LONG TO STOP THERE AND PICK UP FANNY.

>> HOLD ON TO YOUR HORNS, FOLKS!

[BELL RINGS] FABROSAURUS FIELDS STATION IN THE JURASSIC TIME PERIOD!

[STEAM HISSES] >> MR.

CONDUCTOR!

HOW ARE YOU?

I HEARD THE DINOSAUR TRAIN, AND I CAME TO SEE IF YOU WERE ON-BOARD.

>> NICE TO SEE YOU, FANNY.

OH, AND PLEASE MEET MY JUNIOR CONDUCTOR FRIENDS, BUDDY AND TINY.

>> HELLO.

>> I BELIEVE MISS TINY HAS A PROPOSITION FOR YA, OR BIG IDEA.

>> REALLY?

HOW EXCITING!

WHAT IS IT?

>> WOULD YOU COME ON-BOARD AND WE CAN EXPLAIN IT TO YOU EN ROUTE?

>> I'D LOVE TO.

>> ALL ABOARD!

>> AND I'M THE "F"?

[GASPS] IF THAT ISN'T THE GREATEST IDEA I HAVE EVER HEARD!

WE COULD ALL GO DOWN IN DINOSAUR TRAIN HISTORY.

YOU'LL BE REMEMBERED AS THE MOST FAMOUS CONDUCTOR EVER!

>> REALLY?

HEH!

GOSH.

>> ISN'T TINY'S BIG IDEA THE BEST, MR. EINIOSAURUS?

A ONCE-IN-A-LIFETIME EXPERIENCE!

>> YES, INDEED.

I'M CONFIDENT THIS A-TO-Z GATHERING WILL HAVE HISTORICAL SIGNIFICANCE.

>> HISTORICAL SIGNIFICANCE?

WHY, OH, I LIKE THE SOUND OF THAT.

>> AND WE'LL LEARN SO MUCH ABOUT ALL THESE DIFFERENT DINOSAURS.

>> KIDS, DID YOU KNOW THAT LISTING DINOSAURS IN ALPHABETICAL ORDER--FROM A TO Z--IS ONE OF MANY WAYS WE PUT DINOSAURS INTO GROUPS?

IT'S CALLED CLASSIFICATION.

>> CLASSIFICATION!

>> AND THERE ARE LOTS OF OTHER WAYS TO CLASSIFY CREATURES, LIKE HERBIVORES AND CARNIVORES.

NOW, JUNIOR CONDUCTORS, WHAT LETTER IS NEXT ON OUR LIST?

>> "G." GALLIMIMUS!

>> GALLIMIMUS, HUH?

WELL, NOW, WE'RE GONNA NEED TO GO BACK TO THE CRETACEOUS TIME PERIOD TO PICK UP MY OLD GALLIMIMUS FRIEND, A THEROPOD NAMED GABBY.

>> IS THERE A TIME TUNNEL THAT CAN TAKE US THERE, MR.

CONDUCTOR?

>> WELL, IF THERE ISN'T, WELL, THEN WE ARE JUST GONNA HAVE TO DIG ONE, BUDDY.

TIME TUNNEL!

TIME TUNNEL APPROACHING!

WE ARE GOING BACK TO THE CRETACEOUS!

[TRAIN BELL RINGS] NEXT STOP, GALLIMIMUS GULCH STATION IN THE CRETACEOUS TIME PERIOD.

>> GALLIMIMUS.

I WONDER WHAT THEY'RE LIKE.

>> GALLIMIMUS SOUNDS A LITTLE LIKE ORNITHOMIMUS.

MAYBE THEY'RE SMALL AND SPEEDY.

[BRAKES SCREECH, STEAM HISSES] >> HELLO, GABBY.

LONG TIME, NO SEE.

>> MR.

CONDUCTOR, HELLO!

LOTS OF DINOSAURS ON-BOARD TODAY.

>> INDEEDY DO, GABBY.

OH, WE CAN EXPLAIN.

BUDDY, TINY, WILL YOU DO THE HONORS?

>> [BOTH TALKING AT ONCE] >> ...AND THEN WE'RE GONNA HAVE A PICNIC.

>> I'M IN!

LET'S DO IT!

COME ON!

>> ALL ABOARD!

>> WELL, NICE TO MEET YOU, DEREK.

THEROPOD DINOSAUR, EH?

YOU LOOK FAST.

>> I'M PRETTY FAST, BUT, YOU KNOW, SO IS BUDDY.

>> HA HA HA!

I'M PRETTY SURE I'M NOT AS FAST AS A GALLIMIMUS.

LOOK AT THOSE LEGS.

>> YUP.

OH, I'M ALL ABOUT SPEED.

I LOVE RUNNING FAST.

TAKE A LOOK AT THIS.

[GRUNTING] >> HOOTIN' HADROSAUR!

SHE'S FAST!

>> WHEN WE GET BACK TO TROODON TOWN, WE CAN HAVE A FOOT RACE, SEE WHO'S THE FASTEST OF ALL THE 26 DINOSAURS IN THE "A TO Z" SONG.

>> THAT WOULD BE SO COOL.

I'M SURE THERE'S LOTS OF OTHER FAST DINOSAURS IN THE SONG.

>> SO FAR, WE'VE PICKED UP "A," "B," "C," "D," "E," "F," AND "G." WHO'S NEXT?

>> MAYBE YOU COULD SING IT FOR US.

HADROSAURUS ♪ >> HI THERE.

I'M DR. SCOTT, THE PALEONTOLOGIST.

YOU PROBABLY KNOW BY NOW THAT DINOSAURS CAME IN ALL SHAPES AND SIZES.

THERE WERE GIANT, MEAT-EATING THEROPODS LIKE T. REX, AND EVEN BIGGER PLANT-EATING SAUROPODS LIKE APATOSAURUS.

THERE WERE LITTLE DINOSAURS, SUCH AS TINY FEATHERED MICRORAPTOR, AND BIRDS LIKE ARCHAEOPTERYX.

SOME DINOSAURS, LIKE CORYTHOSAURUS AND CRYOLOPHOSAURUS, HAD CRESTS.

AND THEN OTHERS, LIKE TRICERATOPS AND EINIOSAURUS, HAD HORNS AND FRILLS.

SCIENTISTS HAVE A WORD FOR SUCH A WIDE VARIETY.

WE CALL IT DIVERSITY.

THE PTERANODON KIDS ARE HELPING TO GATHER A GREAT DIVERSITY OF DINOSAURS--26 DIFFERENT KINDS.

NOW, 26 SOUNDS LIKE A LOT, BUT PALEONTOLOGISTS HAVE DISCOVERED ALMOST 1,000 DIFFERENT KINDS OF DINOSAURS.

ONE DINOSAUR SPECIES THE PTERANODON FAMILY JUST MET IS GALLIMIMUS, A CRETACEOUS THEROPOD WITH BIG EYES, A LONG NECK AND A LONG TAIL AND LONG LEGS.

WE THINK IT WAS A FAST RUNNER, A LOT LIKE THIS MODERN-DAY ANIMAL, THE OSTRICH.

EVERY YEAR, PALEONTOLOGISTS LIKE ME DISCOVER NEW KINDS OF DINOSAURS AND OTHER PREHISTORIC CREATURES, AND THERE'S PLENTY MORE OUT THERE WAITING TO BE DISCOVERED.

MAYBE YOU'LL GROW UP TO BE A PALEONTOLOGIST AND DISCOVER SOME AMAZING NEW CREATURES.

OK, KEEP WATCHING FOR MORE DINOSAUR DISCOVERIES.

>> HELLO, FOLKS.

IT'S ME, THE CONDUCTOR.

TODAY, THE PTERANODON FAMILY CONTINUES TO COLLECT ALL THE DIFFERENT SPECIES IN THE SONG "DINOSAURS, A TO Z."

SO COME ON ALONG WITH ME ON THE DINOSAUR TRAIN!

ALL ABOARD!

>> [TINY SQUAWKS] ISN'T OUR "DINOSAURS, A TO Z" TRIP GOING GREAT, BUDDY?

>> YEAH.

SO MANY SPECIES OF DINOSAURS ARE ALREADY ON-BOARD WITH US.

WE HAVE AN "A," A "B," A "C," A "D," AN "E." >> DON'T FORGET "F" AND "G." NOW WE JUST HAVE TO INVITE THE REST OF THE ALPHABET DINOSAURS ONTO THE TRAIN, AND THEN WE'LL ALL RIDE TO TROODON TOWN FOR A BIG PICNIC.

>> [ALL CLAMOR] >> WE STILL HAVE A LOT OF DINOSAURS TO MEET AND INVITE ON-BOARD.

THIS IS PERFECT.

ARLENE, ELLIOTT, COULD YOU FLY AROUND THE CRETACEOUS AND JURASSIC, AND TELL ALL THE DINOSAURS IN THE "A TO Z" SONG ABOUT THE BIG IDEA, AND INVITE THEM TO RIDE THE DINOSAUR TRAIN WITH US?

LIKE OTHER ANKYLOSAURS, NODOSAURUS HAD BONY ARMOR COVERING ITS BODY FROM THE TIP OF ITS NOSE ALL THE WAY TO THE TIP OF ITS TAIL.

BUT LOOK.

UNLIKE SOME ANKYLOSAURS, NODOSAURUS DIDN'T HAVE A BONY CLUB ON THE END OF ITS TAIL.

BECAUSE NODOSAURUS PROBABLY COULDN'T USE ITS TAIL TO FIGHT OFF MEAT EATERS, PALEONTOLOGISTS THINK IT MAY HAVE DEFENDED ITSELF BY GETTING LOW TO THE GROUND SO ONLY ITS BONY ARMOR WOULD SHOW.
