[kids cheering] - [squawks] MR.

CONDUCTOR, WHAT'S TODAY'S SUPER EXCITING SPORTING EVENT?

- GLAD YOU ASKED, MISS TINY.

TODAY IS THE BIGGEST AND BEST EVENT OF ALL, THE ULTIMATE FACE-OFF!

- HOORAY!

THE ULTIMATE FACE-OFF.

WAIT, WHAT'S THE ULTIMATE FACE-OFF?

- WELL, IT'S CALLED THAT BECAUSE PAIRS OF DINOSAURS FROM EACH TIME PERIOD FACE OFF, COMPETING TO DEMONSTRATE STRENGTH, ENDURANCE, AND AGILITY IN A KIND OF WRESTLING MATCH.

kids: A WRESTLING MATCH?

- INDEEDY-DO!

THE FACE-OFFS ARE CHOSEN FROM THE TOP CARNIVORE PREDATORS OF EACH TIME PERIOD AND THE TOP HERBIVORE QUADRUPEDS THAT DEFEND THEMSELVES WITH THEIR SPECIAL FEATURES.

- LIKE HORNS AND ARMOR?

- RIGHT, BUDDY!

AND THE TEAM FROM THE TIME PERIOD THAT PUTS ON THE MOST ENTERTAINING SHOW WINS!

FROM THE CRETACEOUS, WE HAVE T. REX FACING OFF WITH TRICERATOPS.

IT'LL BE TEETH AND CLAWS VERSUS HORNS!

kids: OOH!

- HIGH-TWO, TANK!

- HIGH-FOUR, BUDDY!

- AND FROM THE JURASSIC, WE HAVE-- - OH!

ALLOSAURUS AND STEGOSAURUS?

- ABSOLUTELY RIGHT, TINY.

IT'S TEETH AND CLAWS VERSUS PLATES AND SPIKES!

[kids cheer] - BUT WHO'S IN THE FACE-OFF FOR TEAM TRIASSIC?

THEY DON'T HAVE BIG CARNIVORES OR BIG QUADRUPEDS.

DO THEY?

- EXCELLENT QUESTION, MISS SHINY.

THE TRIASSIC MATCHUP IS A COUPLE OF DINOSAURS THAT YOU MAY NOT HAVE SEEN BEFORE... ZUPAYSAURUS AND RIOJASAURUS!

kids: COOL!

- NOTE THE PAIR OF PARALLEL CRESTS ON ZUPAYSAURUS'S HEAD.

IT HAS SPEED, AGILITY, CLAWED FEET AND HANDS, AND A MOUTH FULL OF SHARP TEETH!

- RAWR!

YEAH!

- AND ZUPAYSAURUS IS PAIRED AGAINST RIOJASAURUS, A QUADRUPEDAL HERBIVORE, WHICH COMES FROM A FAMILY CALLED PROSAUROPODS.

kids: PROSAUROPODS!

- SO HOW CAN THE HERBIVORE RIOJASAURUS PROTECT ITSELF AGAINST THE CARNIVORE ZUPAYSAURUS?

- YEAH, HE DOESN'T HAVE HORNS LIKE TRICERATOPS.

- OR SPIKES LIKE STEGOSAURUS.

- TRUE, BUT ALTHOUGH ZUPAYSAURUS HAS SPEED AND SHARP TEETH, RIOJASAURUS HAS ITS OWN FEATURES TO HELP WARD OFF PREDATORS!

IT HAS A LONG TAIL AND SIZE TOO; IT'S BIGGER THAN ZUPAYSAURUS!

- WELL, THAT'S ALL PRETTY NEAT, BUT I'M ROOTING FOR TEAM CRETACEOUS ANYWAY.

TO ME, THERE'S NO COOLER MATCHUP THAN TRICERATOPS AND T. REX!

- YEAH!

RAWR!

[all laughing and cheering] - YEP, WE'LL HAVE A WONDERFUL TIME.

[pocket watch chimes] TIME?

IT'S TIME TUNNEL TIME!

TIME TUNNEL!

TIME TUNNEL APPROACHING!

[train whooshing] [shimmering tone] [train whooshing] NEXT STOP, CLASSIC IN THE JURASSIC SPORTS STATION IN THE JURASSIC TIME PERIOD!

FOLLOW ME TO THE ARENA, EVERYONE!

[all murmuring excitedly] - I WONDER WHERE THE TEAM CRETACEOUS ATHLETES ARE.

- [squawks] MAYBE THEY'RE IN THAT BIG TENT.

- COME ON!

kids: BORIS TYRANNOSAURUS!

- OH, HI, KIDS!

SAY, HAVE YOU MET THE OTHER HALF OF TEAM CRETACEOUS?

THIS IS TREVOR TRICERATOPS.

- UNCLE TREVOR!

HI!

- OH, HEY!

HI, TANK.

I'M SO GLAD YOU CAME!

YOU CAN CHEER US ON.

- OH, YEAH!

- WE'RE ALL ROOTING FOR TEAM CRETACEOUS, MR. TRICERATOPS.

kids: YAY!

- AW, PLEASE, CALL ME TREVOR.

kids: OKAY, TREVOR!

- SO DO YOU KIDS HAVE ANY QUESTIONS ABOUT THE BIG FACE-OFF?

- YEAH, DOES ANYONE ACTUALLY GET HURT?

- NOT AT ALL!

THE JUDGES GIVE US POINTS FOR PUTTING ON THE BEST SHOW.

AND TO PUT ON A GOOD SHOW, WE MAKE SURE THAT NEITHER OF US GETS HURT.

SO IT'S ALL ABOUT SHOWMANSHIP, KIDS.

- OOH, SPEAKING OF SHOWMANSHIP, BORIS, WHEN YOU JUMP AT ME AND MAKE LIKE YOU'RE TRYING TO BITE MY FRILL... - OH, RIGHT!

- I WAS THINKING I SHOULD TURN LIKE THIS SO THE CROWD CAN REALLY SEE ALL THREE OF MY BIG HORNS.

- GREAT IDEA!

AND I'LL GO, "YIKES!"

AND JUMP OUT OF THE WAY.

- [laughs] OOH, THE CROWD WILL LOVE IT.

- I HOPE YOU DON'T MIND IF WE GET BACK TO PLANNING OUR MOVES, KIDS.

- IT'S OKAY.

YOU PROBABLY NEED TO FOCUS.

THANKS FOR TALKING TO US ABOUT YOUR FACE-OFF, THOUGH!

- YEAH, THANKS UNCLE TREVOR!

- THE CLASSIC IS ABOUT TO BEGIN!

ATHLETES, TO YOUR READY STATIONS!

- [sighs] both: IT'S SHOWTIME!

- WELL, I'M SURE RELIEVED THAT NO ONE'S GONNA GET HURT TODAY.

- ME TOO.

- I'M REALLY EXCITED TO SEE WHAT THE CARNIVORES AND HERBIVORES ARE GONNA DO, THOUGH.

- ANNIE!

- BUDDY!

[both laughing] [crowd cheering] kids: MAYOR KOSMOCERATOPS!

- DINOSAURS, PTEROSAURS, AND ASSORTED CREATURES, WELCOME TO THE CLASSIC IN THE JURASSIC!

TODAY TEAMS FROM EACH TIME PERIOD WILL COMPETE IN THE ULTIMATE FACE-OFF.

[crowd cheers] THE FIRST TEAM TO COMPETE IN THE RING IS TEAM JURASSIC, FEATURING THOSE JURASSIC FAVORITES ALVIN ALLOSAURUS AND MORRIS STEGOSAURUS!

LET'S HEAR IT FROM THE HOME CROWD!

[crowd cheers] - HEY, EVERYBODY.

HOW'S IT GOIN'?

- HELLO!

THANKS!

[roars] - ALLOSAURUS IS FAMOUS FOR ITS STRONG JAWS AND BIG SHARP TEETH.

[crowd cheers and whistles] AND STEGOSAURUS FOR ITS FORMIDABLY SPIKED TAIL.

[crowd cheers and whistles] AS THE CONTESTANTS BATTLE, THEY WILL BE SCORED BY HOW MUCH THEIR FIGHTING MOVES ENTERTAIN THE CROWD.

THE FACE-OFF ENDS WHEN ONE ATHLETE PINS THE OTHER IN THE RING-- THAT IS, HOLDS HIM DOWN ON THE GROUND.

AND LET THE ULTIMATE FACE-OFF BEGIN!

[crowd cheering] - I'M THINKING ALVIN SHOULD WIN THIS ONE.

HE'S SO BIG AND FAST!

- YEAH, BUT DON'T FORGET MORRIS'S BIG SPIKED TAIL.

- OOH!

OOH!

ALVIN'S GOING IN FOR A PIN!

- [roars] OOH!

YIKES!

[crowd cheers] HA-HA!

- [squawks] ALVIN'S GOT MORRIS BY THE NECK!

HE'S GONNA PIN HIM!

- YOU'RE GOIN' DOWN, QUADRUPED!

- BUT LOOK, HE CAN'T REACH AROUND MORRIS'S BIG PLATES.

[crowd gasps] - TASTE THE WRATH OF MY PLATES, MAN.

[grunts] - [groans] - YEAH.

- AND THE PIN GOES TO MORRIS STEGOSAURUS!

[crowd cheers] NEXT UP, IT'S TEAM TRIASSIC WITH THE BIPEDAL CARNIVORE ZIGGY ZUPAYSAURUS VERSUS THE QUADRUPEDAL HERBIVORE RENALDO RIOJASAURUS!

[crowd cheering] - MR.

CONDUCTOR, HOW CAN RIOJASAURUS STOP THAT BIG PREDATOR ZUPAYSAURUS?

- RIOJASAURUS MAY NOT HAVE SPIKES OR HORNS, BUT HIS TAIL IS STILL PRETTY FORMIDABLE.

WHAT HE LACKS IN SIZE, HE MAKES UP IN TAIL SPEED.

[crowd cheering] - IT'S A PIN BY RENALDO RIOJASAURUS!

[crowd cheers] AND NOW PERHAPS THE GREATEST MATCHUP IN THE HISTORY OF DINOSAURS!

FROM THE CRETACEOUS TIME PERIOD...

THE TREMENDOUS TRICERATOPS AND THE TITANIC, TERRIFYING TYRANNOSAURUS REX!

[crowd cheering loudly] kids: GO, TEAM CRETACEOUS!

WHOO!

- GO, UNCLE TREVOR!

- GO, BORIS!

RAWR!

- YES!

THANK YOU!

- YOU'RE TOO KIND!

THANKS!

THANK YOU ALL!

THANK YOU!

THANKS!

- ALL RIGHT, ALL RIGHT!

START WRESTLING ALREADY!

[crowd cheering] - YEE-HAW!

GET READY TO RUMBLE!

OR MAYBE TUMBLE!

- OOH!

[laughs] [roars] - WOW, TREVOR'S GOING IN WITH HIS THREE LONG POINTY HORNS.

- BUT BORIS IS TOO QUICK.

HE KEEPS USING HIS LONG LEGS TO JUMP OUT OF THE WAY.

kids: IT'S SO EXCITING!

- YOU SEEM PRETTY JUMPY, BORIS.

- HEY, LOOK!

IS THAT A QUETZALCOATLUS?

- HUH?

- HA!

MADE YA LOOK!

HA-HA!

YEE-HAW!

RIDE 'EM, TYRANNOSAUR!

YAHOO-HOO!

WHOA!

WHOA!

- [growls] NOW I'M REALLY MAD!

- EEK!

A LITTLE HELP?

HA-HA!

- [grunts] OH.

- BLESS MY 15 CURLY HORNS!

IT'S A PIN FOR BORIS TYRANNOSAURUS!

[crowd cheering loudly] - THE T. REX BEAT THE TRICERATOPS!

THE T. REX BEAT THE-- OH.

SORRY, TANK.

I DIDN'T MEAN TO HURT YOUR FEELINGS, BEING A TRICERATOPS... - AW, DON'T WORRY ABOUT IT, BUDDY.

THAT WAS THE BEST ULTIMATE FACE-OFF EVER!

- THE JUDGES HAVE MADE THEIR DECISION.

WHILE TEAM TRIASSIC GOT HIGH MARKS FOR THEIR ENERGETIC PERFORMANCE, AND TEAM JURASSIC GOT THEIR PIN THE FASTEST, ULTIMATELY, THEY MUST GIVE THE TROPHY TO TEAM CRETACEOUS FOR THE MOST FUN CROWD-PLEASING SHOW OF ALL!

[crowd cheering] - [squawks] BEST SPORTS DAY EVER!

READY?

OKAY!

kids: GO TEAM CRETACEOUS!

[cheering] [train whistle toots] - WELL, YOU KNOW WHAT THAT MEANS, KIDS.

TIME TO GET BACK TO THE DINOSAUR TRAIN!

- YEAH!

- COME ON!

RACE YA!

[laughter] all: ♪ IT'S THE CLASSIC IN THE JURASSIC ♪ ♪ DINOSAURS FROM FAR AND NEAR ♪ ♪ YEAH, IT'S THE CLASSIC IN THE JURASSIC ♪ ♪ THE SPORTING EVENT OF THE YEAR ♪ ♪ ♪ - HOO!

- HI THERE.

I'M DR. SCOTT THE PALEONTOLOGIST.

THERE WERE MANY DOME-HEADED DINOSAURS.

THEY PROBABLY USED THEIR THICK DOMES TO TRY TO SHOW THAT THEY WERE THE STRONGEST.

THE LARGEST OF THE DOME HEADS WAS A PLANT-EATING DINOSAUR CALLED "PACHYCEPHALOSAURUS," A NAME THAT MEANS "THICK-HEADED LIZARD."

PACHYCEPHALOSAURUS LIVED ALONGSIDE T. REX, BUT THE BONY DOME OF THIS PLANT EATER PROBABLY WASN'T USED TO FIGHT OFF THE GIANT MEAT EATER.

INSTEAD, MANY PALEONTOLOGISTS THINK THAT PACHYCEPHALOSAURUS USED ITS THICK DOME TO THE BUTT THE SIDES OF OTHER PACHYCEPHALOSAURUS.

OTHER DINOSAURS, SUCH AS EINIOSAURUS, PROBABLY USED THEIR HEADGEAR TO FIGHT WITH EACH OTHER TOO.

TODAY ANIMALS HAVE LOTS OF DIFFERENT WAYS TO FIGURE OUT WHO'S THE BIGGEST AND STRONGEST.

MANY SPECIES USE HORNS TO FIGHT EACH OTHER.

CHECK OUT THESE AFRICAN ANTELOPES.

THE MALE ANTELOPES LOCK HORNS TOGETHER AND HAVE PUSHING AND SHOVING CONTESTS.

AND HOW ABOUT THESE MOUNTAIN GOATS?

THE MALES USE THEIR SHARP POINTED HORNS TO HIT THE SIDES OF OTHER MOUNTAIN GOATS.

BECAUSE SO MANY KINDS OF ANIMALS TODAY USE THEIR HEADGEAR MOSTLY TO FIGHT WITH OTHERS OF THE SAME KIND, PALEONTOLOGISTS THINK THAT A LOT OF DINOSAURS, LIKE PACHYCEPHALOSAURUS, DID THE VERY SAME THING.

OKAY, KEEP WATCHING FOR MORE DINOSAUR DISCOVERIES.

- HELLO, FOLKS.

IT'S ME, THE CONDUCTOR.

TODAY WE'RE GOING BACK IN TIME BEFORE THE AGE OF DINOSAURS, WHERE BUDDY AND TINY MEET A CREATURE CALLED DIMETRODON.

SO COME ON ALONG WITH ME ON THE DINOSAUR TRAIN.

ALL ABOARD!

- IMAGINE BEING THE FIRST DINOSAUR.

- THE FIRST ONE EVER?

LIKE ERMA EORAPTOR IN THE TRIASSIC?

- I WONDER IF THERE WERE DINOSAURS EVEN BEFORE ERMA.

- BUT THE BEGINNING OF THE TRIASSIC TIME PERIOD WAS THE BEGINNING OF TIME, RIGHT?

THERE CAN'T BE ANYTHING BEFORE THE AGE OF DINOSAURS.

- I DON'T KNOW.

BUT I BET IF WE WENT ALL THE WAY TO THE BEGINNING OF THE TRIASSIC, MAYBE WE COULD FIND OUT.

- YEAH, MAYBE OUR TRIASSIC FRIEND ERMA EORAPTOR COULD HELP US!

- [squawks] - DID YOU SAY ERMA EORAPTOR?

- WE WONDERED IF WE COULD ASK ERMA IF THERE WAS ANYTHING BEFORE THE TRIASSIC.

- HMM, THAT'S A VERY GOOD QUESTION.

SOUNDS LIKE WE COULD BE IN FOR AN ADVENTURE.

- OOH!

COULD WE TAKE THE DINOSAUR TRAIN AND VISIT ERMA, MOM?

- WELL, WE ALL LOVE THE DINOSAUR TRAIN AND SEEING ERMA.

YOUR DAD AND SHINY AND DON ARE OFF FISHING, SO WE CAN MEET THEM BACK HERE FOR DINNER!

READY?

both: TO THE DINOSAUR TRAIN!

WHOO-HOO!

- IS THERE ANYTHING BEFORE THE AGE OF THE DINOSAURS?

INTERESTING QUESTION, BUDDY AND TINY.

- WE THOUGHT VISITING ERMA EORAPTOR TODAY COULD HELP ANSWER IT.

- ERMA?

YES!

LET'S VISIT ERMA NOW!

I MEAN... [clears throat] ERMA EORAPTOR IS INDEED THE PERFECT CREATURE TO TALK TO ABOUT YOUR "TIME BEFORE TRIASSIC" QUESTION.

- GREAT!

- OH, SHE IS GREAT, ISN'T SHE?

I KNOW JUST WHERE TO FIND ERMA TOO.

AND SINCE I'M A SPECIAL FRIEND OF HERS, MAY I TAG ALONG?

both: SURE!

- WE'D LOVE IT!

- MR.

CONDUCTOR, DO YOU KNOW ANYTHING ABOUT THE TIME BEFORE DINOSAURS?

I MEAN, WAS THERE A TIME BEFORE THE DINOSAURS?

- BUDDY, TINY, THERE WERE ACTUALLY BILLIONS OF YEARS BEFORE THE MESOZOIC ERA!

AND THE TIME RIGHT BEFORE THE TRIASSIC IS CALLED THE PERMIAN TIME PERIOD, WHICH WAS PART OF THE BIGGER PALEOZOIC ERA.

both: THE PERMIAN TIME PERIOD IN THE PALEOZOIC ERA!

- PRECISELY!

IN THIS EARLIER TIME PERIOD, THERE WERE ALL KINDS OF AMAZING CREATURES IN THE SEA AND ON LAND, SUCH AS DIMETRODON!

- WOW.

WHAT KIND OF DINOSAUR IS THAT?

- NEWS FLASH, TINY.

DIMETRODON IS NOT A DINOSAUR, BECAUSE THERE WERE NO DINOSAURS IN THE PERMIAN.

both: [gasp] NO DINOSAURS?

- THERE WERE NO DINOSAURS BEFORE THE TRIASSIC TIME PERIOD.

DIMETRODON BELONGED TO AN ANIMAL GROUP CALLED SYNAPSIDS, WHICH INCLUDES THE ANCESTORS OF ALL MAMMALS.

- I HAVE A HYPOTHESIS!

MAYBE DIMETRODON USED ITS FIN FOR SHOWING OFF.

- GOOD THINKING, BUDDY!

IT'S LIKELY THAT IT USED ITS SAIL FIN TO SHOW OFF, JUST LIKE HOW THEROPODS USE THEIR CRESTS.

OR DIMETRODON MAY HAVE ALSO USED ITS FIN TO CONTROL ITS BODY TEMPERATURE.

- WAS DIMETRODON A HERBIVORE?

- DIMETRODON WAS A CARNIVORE, AND VERY LIKELY ONE OF THE TOP CARNIVORES IN ITS ECOSYSTEM.

- I WISH I COULD MEET THIS OTHER TOP CARNIVORE.

- WELL, MAYBE WE CAN!

HERE'S THE PLAN: WE'LL RIDE THE TRAIN BACK TO THE TRIASSIC, FIND ERMA, THEN WE CAN TAKE THE HANDCARTS DOWN THE LITTLE TRACK TO THE END OF THE TRAIN LINE.

- YAY!

THE HANDCARTS ARE SO MUCH FUN!

- AREN'T THEY?

AND AT THE END OF THE LINE, WE CAN WALK THROUGH A LITTLE-KNOWN, PEDESTRIANS-ONLY TIME TUNNEL THAT WILL BRING US EVEN FURTHER BACK IN TIME, HOPEFULLY TO THE PERMIAN.

- OH!

WHAT AN ADVENTURE!

IT SOUNDS WONDERFUL, MR.

CONDUCTOR!

- I THINK IT'S TIME FOR A TINY DITTY... ABOUT TIME!

WE'RE FROM THE MESOZOIC, THE AGE OF DINOSAURS.

BUT THERE'S A PALEOZOIC AGE, THE TIME THAT CAME BEFORE.

♪ LONG BEFORE OUR CRETACEOUS TIME ♪ ♪ WAS A PERIOD CALLED JURASSIC ♪ ♪ AND EVEN FURTHER BACK IN TIME ♪ ♪ WAS A TIME WE CALL TRIASSIC ♪ BUT NOW WE'RE GOING FURTHER BACK TO A TIME BEFORE THAT TIME, BEFORE THE AGE OF DINOSAURS... ♪ WHO KNOWS WHAT THINGS WE'LL FIND ♪ [squawks] [pocket watch chimes] - AND SPEAKING OF TIME, MISS TINY... TIME TUNNEL!

TIME TUNNEL APPROACHING!

[train whooshing] NEXT STOP, EORAPTOR RAVINE STATION IN THE TRIASSIC TIME PERIOD!

all: HI, ERMA!

- WELL, HI, PTERANODONS.

I HEARD THE TRAIN COMING IN, MAKIN' ALL THAT COMMOTION, SO I MOSEYED OVER.

GLAD I DID.

- I SHALL LOOK AFTER THE DINOSAUR TRAIN WHILE YOU'RE ON YOUR PRE-MESOZOIC ADVENTURE, SONNY BOY.

GO.

EXPLORE!

TAKE A RISK!

TRY SOMETHING NEW!

GET OUT OF YOUR COMFORT ZONE!

BUT DON'T FORGET TO HAVE FUN!

[laughs] DID I FORGET ANYTHING?

OH, HELLO, ERMA!

- MA'AM, GOOD TO SEE YA.

WELL, HELLO, MR.

CONDUCTOR.

- OH, ERMA, I'M SO VERY HAPPY TO SEE YOU.

OOH, SO HAPPY.

- WELL, I'M OVER THE MOON SEEING YOU, MR.

CONDUCTOR, YA OLE TROODON.

- [squawks] ERMA, WE HAVE A QUESTION.

- OF COURSE.

ASK AWAY, MISS TINY.

- WE WERE HOPING TO GO BACK IN TIME THROUGH THE PEDESTRIAN TIME TUNNEL.

- HONEST TRUTH?

NEVER BEEN THROUGH THAT WALKIN' TIME TUNNEL, BUT I'VE SEEN IT.

IT'S STILL THERE.

- WE WERE THINKING WE COULD VISIT THE PERMIAN TIME PERIOD, MAYBE EVEN MEET A DIMETRODON!

- ARE YOU UP FOR IT, MR.

CONDUCTOR?

- WITH YOU AT MY SIDE?

YOU KNOW I AM, ERMA!

- THEN LET'S GO WAY BACK IN TIME.

I CERTAINLY HOPE TO MEET A DIMETRODON, DON'T YA KNOW.

kids: YAY!

THANKS, ERMA!

- TO THE HANDCARTS!

[squawks] - END OF THE LINE, FOLKS.

AND THERE IT IS, THE WALKIN' TIME TUNNEL.

- JUST STICK CLOSE TO ME, KIDS.

- READY, ERMA?

HERE WE GO!

[air whooshing] IT'S SO FASCINATING, WALKING TO AN EARLIER ERA.

THIS IS BEYOND ALL KNOWN TROODON TECHNOLOGY!

- YOU OKAY, TINY?

- WELL, I GUESS I'M A LITTLE NERVOUS ABOUT GOING SO FAR BACK IN TIME.

- I UNDERSTAND.

BUT WE'RE ALL HERE WITH YOU ON ANOTHER FUN ADVENTURE.

- AND I BET WE'LL GET TO DO ONE OF YOUR FAVORITE THINGS-- MEET A NEW CREATURE.

- MAYBE EVEN MAKE A NEW FRIEND.

NOTHIN' BETTER THAN THAT.

- YOU'RE RIGHT!

THANKS, EVERYONE!

TINY POWER!

- OOH!

I CAN SEE THE LIGHT AT THE END OF THE TUNNEL!

ALWAYS LOVE TO SAY THAT.

JUST A FEW MORE STEPS TO THE PERMIAN.

- READY, TINY?

- [squawks] I THINK SO.

LET'S GO!

- DINOSAURS AND PTEROSAURS, I BELIEVE WE ARE IN THE PERMIAN TIME PERIOD!

- HMM, IT FEELS DIFFERENT BUT ALSO KIND OF THE SAME AS OTHER PLACES.

- LOOK, THERE'S SOME MOSS AND GINGKO AND FERNS JUST LIKE AT HOME.

- YEAH, BUT LOOK AT THAT WEIRD-LOOKING PLANT.

THAT'S DIFFERENT.

both: WHOA!

IT'S MOVING!

- [squawks] IS IT A PLANT, MR.

CONDUCTOR?

- [yelps] - TINY!

LOOK ON ITS BACK.

A SAIL FIN!

- HELLO!

ARE YOU A DIMETRODON?

- SURE AM.

I'M DEON DIMETRODON.

- WE'RE SO EXCITED TO MEET YOU, DEON!

WE'RE FROM THE MESOZOIC ERA IN THE FUTURE!

[squawks] - THE MESOZOIC ERA?

I'VE HEARD ABOUT THAT.

REALLY?

- REALLY!

I'M TINY PTERANODON.

THIS IS MY BROTHER, BUDDY, AND OUR MOM, MOM!

AND THIS IS MR.

CONDUCTOR AND ERMA EORAPTOR.

all: HELLO!

- HI!

- DEON, I REALLY LIKE TO COMPARE FEATURES.

WOULD YOU MIND IF WE DO A FEATURE CHECK?

- CHECK AWAY!

- YOU HAVE FOUR LEGS AND AN AMAZING SAIL FIN.

- YUP, IT HELPS ME COOL OFF.

- BUDDY, I GUESS YOUR HYPOTHESIS WAS WRONG.

IT'S NOT FOR SHOWING OFF; IT'S FOR COOLING OFF!

IT IS HOT HERE, ISN'T IT?

- AND I SEE YOU WALK CLOSE TO THE GROUND.

- TRUE.

PUTS ME CLOSER TO THE FOOD.

- I'M A CARNIVORE TOO.

I'M GOING TO GROW UP TO BE BIG.

- REALLY BIG, ONE OF THE BIGGEST DINOSAURS EVER!

- WAIT.

YOU'RE DINOSAURS?

I THOUGHT THEY WERE JUST MADE UP LIKE IN STORIES.

- WELL, I'M A DINOSAUR, A T. REX.

- I'M WHAT YOU CALL AN EORAPTOR, ONE OF THE VERY FIRST DINOSAURS.

- I'M A TROODON.

WE'RE THE SMARTEST DINOSAURS.

- MOM AND I AREN'T DINOSAURS.

WE'RE PTERANODONS, FLYING PTEROSAURS.

- WAIT.

YOU CAN FLY?

- COME ON, MOM.

LET'S SHOW HIM!

[both squawk] - WOW.

OH, THIS IS GREAT!

AROUND HERE, THE BIGGEST WINGS YOU COULD FIND WOULD BE ON A LITTLE DRAGONFLY.

- [giggles] - BOY, HAVING THOSE KIND OF WINGS WOULD SURE CHANGE EVERYTHING.

IT WOULD BE EASIER TO GIVE YOU FOLKS A TOUR.

- WOULD YOU GIVE US A TOUR, DEON?

- MY PLEASURE!

- OH MY STARS, A TOUR OF THE PERMIAN.

IT'S LIKE A DREAM COME TRUE.

- INDEED IT IS, ERMA.

- MOSS AND GINGKO... LIZARDS.

PERFECT FOR A SNACK.

- [chomps] [both chomp] - MMM, THIS PRE-MESOZOIC MEAL HITS THE SPOT, ESPECIALLY SINCE I'M SHARING IT WITH YOU, ERMA.

- OH, YOU CHARMING TROODON, YOU.

- YEAH, IT'S PRETTY HOT AND HUMID HERE IN THE PERMIAN, AT LEAST WHERE I LIVE.

LUCKY I HAVE THIS SAIL FIN!

- SURE WISH I HAD A SAIL FIN TODAY!

- [laughs] MAYBE THIS'LL COOL EVERYONE OFF.

[laughs] - THANKS, TINY.

WELL, THIS ADVENTURE HAS BEEN SO MUCH FUN, BUT WE SHOULD REALLY HEAD BACK TO THE MESOZOIC AND THEN HOME.

both: AW.

- MAYBE WE CAN VISIT AGAIN SOMETIME?

- I PROMISE WE WILL.

WE CAN JUST WALK THROUGH THE PEDESTRIAN TIME TUNNEL.

- HUH, I'VE ALWAYS WONDERED ABOUT THAT TUNNEL, AND I'D LOVE TO VISIT THE MESOZOIC.

PROBABLY BE THE FIRST DIMETRODON EVER TO DO IT!

- WHY NOT COME ALONG WITH US RIGHT NOW?

LET'S GO!

- WELL, THIS IS AN ODD EXPERIENCE.

- I UNDERSTAND, DEON.

BUT WE'RE ALL HERE WITH YOU ON A REALLY FUN ADVENTURE.

READY, DEON?

- [exhales deeply] I THINK SO.

LET'S DO IT.

[air whooshing] WOW!

NOW, THIS IS ONE TALL TREE!

AND LOOK AT THOSE-- DINOSAURS, RIGHT?-- JUST RUNNING BY.

[gasps] REMARKABLE!

ANOTHER FLYING CREATURE!

THINGS SURE LOOK DIFFERENT IN THE FUTURE.

MMM!

AND THINGS SURE TASTE YUMMIER IN THE FUTURE.

[train whistle toots] WHOA, AND THINGS ARE SURE LOUDER IN THE FUTURE.

- WELL, THAT MEANS IT'S TIME FOR US TO HEAD HOME.

IT WAS WONDERFUL MEETING YOU, DEON.

both: BYE, DEON!

- THANKS FOR SHOWING US THE PERMIAN!

- THANK YOU!

I'M SO GLAD THAT I GOT TO SEE THE MESOZOIC.

FRANKLY, I WASN'T CERTAIN IT REALLY EXISTED.

BYE, EVERYONE!

BACK I GO.

FAREWELL, ERMA, FOR NOW.

- SO LONG, MY MUSHY TROODON PRINCE.

- TIME TO RUN THE TRAIN, SONNY BOY!

CHOP-CHOP!

OOH, GOODBYE, ERMA!

- NO TEARS, NOW.

SEE YA SOON, DON'T YA KNOW.

- [sniffles] [cries] ALL ABOARD!

all: BYE, ERMA!

- HI THERE.

I'M DR. SCOTT THE PALEONTOLOGIST.

MILLIONS OF YEARS BEFORE THE CRETACEOUS TIME PERIOD WHEN BUDDY AND TINY LIVED, THERE WAS ANOTHER TIME PERIOD CALLED THE PERMIAN.

THE PERMIAN WAS EVEN BEFORE THE AGE OF DINOSAURS, WHICH MEANS THAT NO DINOSAURS LIVED AT THIS TIME.

BUT MANY CREATURES IN THE PERMIAN SURE LOOKED LIKE DINOSAURS.

ONE OF THEM WAS DIMETRODON.

DIMETRODON WAS AN 11-FOOT-LONG, 500-POUND MEAT EATER AND THE TOP CARNIVORE OF ITS TIME.

THE GIANT SAIL ON ITS BACK MAY HAVE BEEN USED FOR COOLING OFF OR FOR SHOWING OFF.

WE'RE STILL NOT SURE.

UNLIKE DINOSAURS, DIMETRODON HAD LEGS THAT WERE SPRAWLED OUT TO THE SIDES LIKE CROCODILES AND LIZARDS TODAY.

THIS FEARSOME PREDATOR MOVED MUCH LIKE THE MODERN-DAY KOMODO DRAGON.

BUT BELIEVE IT OR NOT, DIMETRODON IS ACTUALLY MORE CLOSELY RELATED TO MAMMALS, LIKE YOU AND ME, THAN TO REPTILES.

OKAY, REMEMBER, GET OUTSIDE, GET INTO NATURE, AND MAKE YOUR OWN DISCOVERIES.

- WE LOVE PLAYING GAMES... - LIKE ALL ABOARD.

- YOU CAN PLAY TOO ONLINE AT: - AND LOTS OF OTHER GAMES.

- THERE'S SO MUCH TO LEARN ABOUT ALL KINDS OF DINOSAURS.
