>> HELLO, MR.

CONDUCTOR.

>> PLAY DATE ON THE DINOSAUR TRAIN?

>> YEP.

WE'RE TAKING A RIDE BACK IN TIME TO MEET A RELATIVE OF TANK'S.

>> IS THAT SO?

>> MY MOM SAYS I HAVE AN ANCESTOR.

>> THAT MEANS A RELATIVE FROM LONG, LONG AGO.

[SQUAWKS] >> UH-HUH.

AN ANCESTOR OF MINE NAMED PENELOPE.

SHE HAS A FRILL, BUT NO HORNS.

>> HMM.

LET'S SEE.

A RELATIVE OF YOURS WITH A FRILL AND NO HORNS.

SOUNDS TO ME LIKE A PROTOCERATOPS.

>> THAT WAS HER NAME--PENELOPE PROTOCERATOPS.

>> OBSERVE.

>> WOW!

PROTOCERATOPS REALLY DOESN'T HAVE ANY HORNS.

MAYBE WE SHOULD BRING HER SOME.

>> BUT WHY DOESN'T SHE HAVE HORNS?

TANK, YOU USE YOUR HORNS FOR PROTECTION, RIGHT?

>> SOMETIMES.

SURE.

>> SO IF PROTOCERATOPS DON'T HAVE HORNS, MAYBE SHE DOESN'T HAVE TO PROTECT HERSELF THAT MUCH.

MAYBE THERE AREN'T MANY MEAT-EATING CARNIVORES WHERE SHE LIVES.

>> THAT IS A WELL-THOUGHT-OUT HYPOTHESIS, BUDDY, AND PROTOCERATOPS DOES LIVE IN A DIFFERENT ENVIRONMENT, WITHOUT MANY PREDATORS.

>> WHAT KIND OF ENVIRONMENT DOES PENELOPE LIVE IN?

>> GLAD YOU ASKED, TINY.

MOST PROTOCERATOPS LIVE IN THE DESERT.

>> DESSERT?

DID SOMEONE SAY DESSERT?

>> NO, TANK, THE DESERT.

THAT'S WHERE WE'LL GO TO MEET PENELOPE PROTOCERATOPS.

>> AND THEN MAYBE SHE'LL GIVE US DESSERT.

>> [ALL GIGGLE] >> [SQUAWKS] DO YOU THINK PENELOPE WILL MIND US STOPPING BY?

>> I HAPPEN TO KNOW PENELOPE LOVES VISITORS.

BUT JUST SO YOU KNOW, THE AREA WHERE SHE LIVES DOES TEND TO GET EARTHQUAKES.

>> EARTHQUAKES?

>> YOU MEAN WHEN THE GROUND SHAKES AND SHAKES UNDER YOUR FEET?

UH-UH-UH-UH-UH!

>> HA HA!

>> EXACTLY.

>> UM, IF THERE ARE EARTHQUAKES, THEN MAYBE WE SHOULDN'T GO.

>> EARTHQUAKES ARE SERIOUS, SHINY, BUT EVEN PLACES KNOWN FOR GETTING EARTHQUAKES DON'T GET THEM ALL THE TIME.

ISN'T THAT RIGHT, MR.

CONDUCTOR?

>> WELL, ACTUALLY--AHEM--I MUST SAY THAT EARTHQUAKES DO HAPPEN ALL THE TIME.

THERE'S AN EARTHQUAKE ABOUT EVERY 30 SECONDS SOMEWHERE ON EARTH.

>> REALLY?

>> REALLY?

>> AHEM.

>> BUT MOST EARTHQUAKES ARE VERY SHORT AND NOT THAT STRONG.

WHAT YOUR MOM MEANS IS USUALLY THEY HAPPEN WAY DOWN DEEP, SO UP HERE WE CAN'T EVEN FEEL THEM.

>> BUT WHAT IF YOU'RE IN AN EARTHQUAKE THAT YOU CAN FEEL?

>> FIRST OF ALL, IF IT HAPPENS, YOU SHOULD LISTEN TO THE GROWNUPS, AND THERE ARE THINGS WE CAN DO TO PROTECT OURSELVES IN AN EARTHQUAKE.

>> ABSOLUTELY.

STAY CALM AND DON'T RUN AROUND.

BEST THING TO DO IS STAY OUT IN THE OPEN AND MOVE AWAY FROM ANYTHING THAT MIGHT COME LOOSE AND FALL ON YOU.

>> LIKE A TREE BRANCH?

>> OR A COCONUT?

>> OR A QUETZALCOATLUS?

>> YES, YES, AND POSSIBLY, DON, BUT HIGHLY UNLIKELY.

>> I DON'T KNOW.

I STILL DON'T LIKE THE SOUND OF IT.

>> I LIKE THE SOUND OF IT.

IT GOES, "UH-UH-UH-UH-UH!"

>> DON, SHE MEANS THAT EARTHQUAKES MAKE HER NERVOUS.

>> I DIDN'T SAY THAT!

>> IT'S ALL RIGHT, SHINY.

YOU'RE NOT ALONE.

BUT REMEMBER, WE NEVER EVEN FEEL MOST EARTHQUAKES.

IT'S THE LAND THAT'S AFFECTED MORE THAN ANYTHING ELSE.

>> THE LAND?

LIKE THE GROUND AND TREES AND THINGS?

>> EXACTLY, BUDDY.

OVER A LONG, LONG, LONG TIME, EARTHQUAKES CHANGE THE WAY LAND LOOKS.

THEY CAN EVEN MAKE MOUNTAINS.

>> EARTHQUAKES CAN MAKE MOUNTAINS?

>> HOW?

>> THE SURFACE OF THE EARTH IS BROKEN UP INTO GIANT CHUNKS CALLED PLATES.

>> LIKE THE KIND WE EAT OFF OF ON THE DINOSAUR TRAIN?

>> MAYBE THAT'S WHY I LIKE EATING PLANTS SO MUCH.

THEY'RE SERVED UP ON GIANT PLATES.

>> [ALL GIGGLE] >> INTERESTING THEORY, BUT THESE PLATES ARE DIFFERENT.

THEY'RE GIANT, GIANT, GIANT STRETCHES OF LAND.

THE PLATES MOVE AROUND VERY SLOWLY, AND EVERY NOW AND THEN, THEY BUMP INTO EACH OTHER.

WHEN 2 PLATES PUSH ON EACH OTHER FOR MILLIONS OF YEARS, IN TIME, THEY CAN CAUSE HUGE MOUNTAINS TO FORM.

>> WHOA!

[BELL CHIMES] >> OH!

AND SPEAKING OF TIME, AHEM!

TIME TUNNEL!

TIME TUNNEL APPROACHING!

NEXT STOP, PROTOCERATOPS SAND STATION!

[BELL RINGS] PROTOCERATOPS SAND STATION IN ANOTHER PART OF THE CRETACEOUS TIME PERIOD!

>> [ALL CLAMOR] >> AWESOME!

>> YEAH!

>> SO LONG, GANG.

SAY HI TO PENELOPE PROTOCERATOPS FOR ME.

>> WE WILL.

BYE, MR.

CONDUCTOR!

>> HOT.

[PANTS] VERY HOT.

>> YEAH, AND I JUST REALIZED I'M HUNGRY.

BUT I BET PENELOPE PROTOCERATOPS HAS ALL KINDS OF GREAT PLANTS TO EAT.

>> YOU THINK SO?

I DON'T SEE ANY PLANTS.

>> BUT PENELOPE'S A CERATOPSIAN, RIGHT?

THAT MEANS SHE'S PART OF MY FAMILY, AND EVERYONE IN MY FAMILY LOVES FOOD.

>> I DON'T SEE MUCH FOOD.

>> SHE PROBABLY HAS ALL KINDS OF LEAF-A-LICIOUS TREATS I'VE NEVER EVEN TASTED BEFORE, LIKE LEAF JERKY OR LEAF-- >> [ALL GASP] >> WHAT IS IT?

>> WHY, HELLO THERE.

>> HI.

ARE YOU PENELOPE PROTOCERATOPS?

>> YES, I AM.

HOW DID YOU KNOW?

>> YOU SCARED US WITH YOUR FRILL.

THAT'S WHAT CERATOPSIANS DO.

>> HA HA HA!

OH, FRILLS CAN BE INTIMIDATING, I SUPPOSE, BUT I MAINLY USE MY FRILL TO GET OTHER PROTOCERATOPS' ATTENTION AND LET THEM KNOW I'M AROUND.

>> HELLO.

I'M TINY PTERANODON, AND THIS IS MY FAMILY: BUDDY, DON, SHINY, AND MOM.

AND OUR FRIEND TANK.

HE'S A CERATOPSIAN, TOO.

>> A TRICERATOPS, RIGHT?

I CAN TELL BECAUSE OF YOUR 3 BEAUTIFUL HORNS.

>> THANKS, AND WE KNEW YOU WERE PROTOCERATOPS BECAUSE YOU DON'T HAVE ANY HORNS, JUST THE LITTLE BUMP ON YOUR NOSE.

>> PENELOPE, I HAVE A HYPOTHESIS ABOUT YOUR HORNS.

>> YOU MEAN AN IDEA YOU CAN TEST?

>> RIGHT.

I THINK YOU DON'T HAVE HORNS BECAUSE THERE AREN'T THAT MANY MEAT-EATING CARNIVORES AROUND HERE.

>> OOH.

WHAT AN INTERESTING HYPOTHESIS, BUDDY.

BUT I'M NOT SURE THAT CERATOPSIANS USE THEIR HORNS TO FIGHT CARNIVORES.

WELL, DO YOU, TANK?

>> NOT REALLY.

I MEAN, MY HORNS LOOK SCARY, SO CARNIVORES WON'T BUG ME, BUT I LIKE TO USE THEM FOR WRESTLING WITH OTHER TRICERATOPS.

>> BUT YOU HAVE A SHARP BEAK LIKE ME.

THAT'S A GREAT WAY TO PROTECT OURSELVES.

>> YEAH, AND IT'S GREAT FOR CHOMPING THROUGH BRANCHES AND LEAVES.

SNACK TIME!

UM, WHAT DO YOU EAT?

>> OH, I CAN MAKE A WONDERFUL MEAL OUT OF SHRUBS AND BRUSH.

BUT WHEN I WANT SOMETHING REALLY JUICY, I HEAD TO THE WATERING HOLE.

EVER TRIED A SHRUBMARINE SANDWICH?

>> NO.

THAT SOUNDS GREAT.

>> IS THAT AN EARTHQUAKE?

>> THAT CAN ONLY MEAN ONE THING.

>> EARTHQUAKE!

>> [SQUAWKS] >> OK, EVERYONE.

REMEMBER WHAT WE DO?

>> YUP.

STAY CALM, DON'T RUN AROUND.

>> AND STAY IN THE OPEN.

IS THERE ANYTHING THAT CAN FALL ON US?

>> NO.

>> UH-UH-UH-UH-UH!

>> IS EVERYONE OK?

>> YES.

>> [SQUAWKS] THAT WAS SO FUN!

AND I WASN'T SCARED AT ALL.

>> SOME LARGE QUAKES CAN BE QUITE SERIOUS, BUT I'M VERY IMPRESSED BY HOW PREPARED YOU ALL WERE.

>> IT'S TRUE.

YOU DID EXACTLY THE RIGHT THING.

YOU STAYED OUT IN THE OPEN, AWAY FROM FALLING OBJECTS, AND DIDN'T PANIC.

I'M VERY PROUD OF ALL OF YOU.

>> THANKS, MOM.

>> WHOA, MOM!

DO YOU SEE THAT?

>> I DON'T SEE ANYTHING.

>> BUDDY HAS KEEN T-REX EYESIGHT.

WHAT DO YOU SEE, BUDDY?

>> OOH!

I SEE IT!

THE GROUND MOVED AND RAISED UP, JUST LIKE MR.

CONDUCTOR SAID.

CAN WE GO SEE?

>> WELL, IT'S PRETTY FAR, AND THE DINOSAUR TRAIN'S COMING BACK SOON.

WE COULDN'T MAKE IT UNLESS WE FLEW, AND I'M AFRAID TANK'S TOO BIG FOR US TO CARRY.

>> THAT'S OK.

I DON'T MIND STAYING HERE, AS LONG AS WE CAN HAVE THAT SHRUBMARINE SANDWICH.

>> YOU BET!

WE CERATOPSIANS CAN STICK TOGETHER.

>> THANKS, PENELOPE.

OK, KIDS, LET'S GO CHECK IT OUT.

>> SHOW US THE WAY, BUDDY!

>> I SEE IT!

THERE IT IS!

>> HELLO DOWN THERE!

I'M KING OF THE BRAND-NEW MOUNTAIN!

♪ LA LA LOO!

♪ >> HMM!

WAS THIS REALLY ALL UNDERGROUND BEFORE THE EARTHQUAKE?

>> AMAZING, ISN'T IT?

YOU CAN EVEN SEE THE DIFFERENT LAYERS OF ROCK.

SOME VERY LARGE PLATES MUST HAVE BEEN PUSHING TOGETHER FOR A LONG TIME TO FINALLY MAKE THIS HAPPEN.

>> I BET, IN MILLIONS AND MILLIONS OF YEARS, AND LOTS OF EARTHQUAKES, THIS WILL BECOME A HUGE MOUNTAIN.

>> BUT NOW, IT'S LIKE A BABY MOUNTAIN.

[SQUAWKS] YES!

WE GOT TO SEE A MOUNTAIN BEING BORN!

>> HAPPY BIRTHDAY, BABY MOUNTAIN.

[RUMBLING] UH-OH.

HERE COMES ANOTHER MOUNTAIN-MAKING EARTHQUAKE.

>> ACTUALLY, HERE COMES THE DINOSAUR TRAIN.

[TRAIN WHISTLE BLOWS] >> [SQUAWKS] WE HAVE TO GO CATCH THE TRAIN, KIDS.

LET'S FLY!

>> BYE-BYE, BABY MOUNTAIN!

>> TANK!

YOU'LL NEVER BELIEVE WHAT WE SAW!

>> WHAT'D YOU SEE, BUDDY?

>> IT WAS JUST LIKE YOU SAID, MR.

CONDUCTOR.

THERE WAS AN EARTHQUAKE, AND IT STARTED A MOUNTAIN!

>> A MOUNTAIN?

REALLY?

>> WELL, A BABY MOUNTAIN.

>> IT WAS SO CUTE!

>> WELL, BLESS MY SCALES AND FEATHERS!

YOU REALLY DID EXPERIENCE AN EARTHQUAKE.

SO, HOW WAS IT?

>> IT WAS GREAT!

WE DID EXACTLY WHAT YOU TOLD US, AND I WASN'T SCARED AT ALL.

OK, MAYBE I WAS A LITTLE.

>> BUT YOU REMEMBERED THE RIGHT THING TO DO, AND THAT'S WHAT'S MOST IMPORTANT.

YOU WOULD HAVE BEEN VERY IMPRESSED.

>> I'D NEVER DOUBT YOU, MRS. P. ALL ABOARD!

>> BYE, PENELOPE!

GREAT TO MEET YOU!

SEE YA!

BYE!

>> HI, THERE.

I'M DR. SCOTT, THE PALEONTOLOGIST, AND THIS IS THE SKULL OF A DINOSAUR THAT WE DISCOVERED RIGHT HERE IN UTAH.

I NAMED IT UTAHCERATOPS.

UTAHCERATOPS WAS A HORNED DINOSAUR, OR CERATOPSIANS, AND THIS WAS A HUGE ANIMAL, ABOUT 20 FEET LONG, BUT MOST IMPRESSIVE OF ALL IS ITS ENORMOUS HEAD, ALMOST 7 FEET LONG.

UTAHCERATOPS HAD A LARGE HORN OVER THE NOSE AND SHORT EYE HORNS THAT STUCK OUT TO THE SIDE.

SIMILAR SIDEWAYS-POINTING HORNS CAN BE SEEN TODAY IN BISON.

UTAHCERATOPS' HORNS ARE DIFFERENT FORM THE HORNS OF ALL OTHER CERATOPSIANS.

TRICERATOPS HAD ONE HORN OVER THE NOSE AND MUCH BIGGER HORNS OVER THE EYES THAT POINTED FORWARD INSTEAD OF TO THE SIDE.

COAHULIACERATOPS ALSO HAD A HORN OVER THE NOSE AND EVEN BIGGER HORNS OVER THE EYES, AND KOSMOCERATOPS, WELL, IT HAD A TOTAL OF 15 HORNS ALL OVER ITS HEAD.

THIS IS THE SKULL OF A SMALL CERATOPSIAN NAMED PROTOCERATOPS.

YOU CAN SEE THAT IT'S TINY COMPARED TO THE SKULL OF UTAHCERATOPS, BUT ALL THESE PLANT EATERS HAVE A LOT IN COMMON, INCLUDING A NARROW TURTLE-LIKE BEAK UP FRONT AND A BIG BONEY FRILL IN THE BACK, AND THEY ALL WALKED ON 4 LEGS.

OK. KEEP WATCHING FOR MORE DINOSAUR DISCOVERIES.

>> HELLO, FOLKS.

IT'S ME THE CONDUCTOR.

TODAY WE'RE GONNA SEE A NEW CAR ON THE TRAIN, THE NURSERY CAR, AND WE JUST MIGHT SEE SOME EGGS HATCHING, SO COME ON ALONG WITH ME ON THE DINOSAUR TRAIN.

ALL ABOARD!

>> I DON'T SEE IT.

>> THE DINOSAUR TRAIN WILL BE HERE VERY SOON, DON.

BE PATIENT.

>> I CAN'T WAIT TO SEE THE NEW CAR!

>> I WONDER WHAT IT WILL LOOK LIKE.

>> I HOPE IT'S SHINY!

>> I THINK YOU'LL ALL LOVE THE NEW NURSERY CAR.

IT'S FULL OF EGGS JUST WAITING TO HATCH AND THEIR PARENTS OF COURSE.

>> WHEN IS IT-- [TRAIN WHISTLE BLOWS] OHH!

HERE IT IS!

>> ALL ABOARD!

[WHISTLE BLOWS] >> HELLO, MR.

CONDUCTOR!

>> GREETINGS, AND WELCOME TO ALL MOMS AND MOMS-TO-BE.

>> WE'RE NOT MOMS.

>> DON'T WORRY, DON.

YOU'RE ALWAYS WELCOME ON THE TRAIN.

OH, AND DADS, TOO!

WELCOME ABOARD THE VERY FIRST RUN OF OUR SPECIAL NEW CAR, THE NURSERY CAR!

[CHEERING] >> AWK!

BUT, MR.

CONDUCTOR, WHERE'S YOUR MOM?

>> OOH!

OOH!

OHH!

BLLLAUGH!

>> AND BLLLAUGH TO YOU TO, MOTHER!

>> OH, HA HA HA!

I'M RIGHT HERE, TINY.

I WOULDN'T MISS THE NEW NURSERY CAR FOR ANYTHING.

IT REMINDS ME OF MY SONNY BOY HERE.

>> OH, MOTHER.

>> CAME OUT OF HIS EGG AND WAS JUST A BITTY BABY DINOSAUR BUT SO CUTE.

>> AW.

>> HA HA!

>> OHH.

>> I WAS JUST THINKING THE SAME THING ABOUT MY 4 BABIES.

IT SEEMS LIKE SO LONG AGO SINCE THEY WERE TINY, LITTLE EGGS.

[RUMBLING] >> OHH!

>> WHAT'S THAT?

>> WHAT WAS THAT?

>> THAT WAS GREAT, WHATEVER IT WAS!

MR.

THE CONDUCTOR, WAS THAT THE EGGS HATCHING?

>> NO, DON.

THAT WAS JUST AN AFTERSHOCK.

>> OOH!

MY EGGS!

>> MY PRECIOUS EGGS!

>> DON'T WORRY, EGGS.

MOMMY'S COMING!

>> EVERYTHING'S FINE, FOLKS.

NO NEED TO PANIC.

>> WHAT EXACTLY IS AN AFTERSHOCK, MR.

CONDUCTOR?

>> WELL, BUDDY, AFTER THAT BIG EARTHQUAKE WE HAD A FEW DAYS AGO, THERE ARE OFTEN A FEW SMALLER QUAKES THAT HAPPEN AFTER.

THAT'S WHY THEY'RE CALLED AFTERSHOCKS, BUT IT'S NOTHING TO WORRY ABOUT NOW THAT IT'S PASSED.

>> AWK!

STILL WORRIED OVER HERE.

>> ME, TOO!

>> CAN WE SEE THE EGGS IN THE NURSERY CAR?

DO YOU THINK THEY'RE OK?

>> OOH!

I'M SURE THE EGGS ARE JUST FINE!

BUT LET'S GO SEE FOR OURSELVES.

>> YEAH!

CAN WE, MOM?

>> AWK!

OF COURSE!

I CAN'T WAIT TO SEE THE EGGS.

[STOMACH GROWLS] >> I'M KIND OF HUNGRY NOW.

CAN I HAVE A FISHWICH BEFORE WE SEE THE EGGS?

>> HEH.

FINE WITH ME, DON.

I THINK I'LL JOIN YOU.

UH, SHINY?

>> YEP.

I'LL STAY WITH YOU, DAD.

>> REMEMBER, KIDS.

WE HAVE THAT SPECIAL SURPRISE TO GIVE MOM LATER.

>> [GIGGLING] >> YEAH.

>> OK, HON.

WE'LL MEET YOU AND TINY AND BUDDY IN THE NURSERY CAR AFTER A FISH SNACK, OK?

>> AWK!

ALL RIGHT.

SEE YOU SOON.

>> HEE HEE HEE!

>> TA-DA!

>> [GASP] >> OH, THIS IS THE MOST BEAUTIFUL CAR I'VE EVER SEEN.

I REMEMBER HOW EXCITED I WAS WHEN YOU GUYS WERE IN LITTLE EGGS JUST LIKE THIS.

OH, THESE EGGS ARE SO CUTE.

>> WELL, THE EGGS ARE INTERESTING BUT NOT THAT CUTE.

>> HEH HEH!

I KNOW WHAT YOU MEAN, TINY, BUT I'M PRETTY SURE THESE MOMS AND DADS DON'T AGREE.

>> WHO'S THE CUTEST EGG?

YOU ARE.

HA HA!

YOU'RE THE CUTEST EGG.

>> HMM.

I SEE A VELOCIRAPTOR MOM AND A TRICERATOPS.

>> AND A MAIASAURA AND A TROODON, AND THEY MUST BE DADS.

>> UNH.

OH, MAN.

OHH.

WHAT AM I GONNA DO?

WHEN'S IT GONNA HAPPEN?

>> CALM DOWN, DADDY.

THEY'LL HATCH WHEN THEY HATCH.

>> HATCH?!

DID SOMEONE SAY, "HATCH"?

>> THIS REALLY IS THE MOST CHARMING PLACE I'VE EVER BEEN.

>> YES.

IT'S THE PERFECT PLACE FOR THE EGGS TO TRAVEL SAFELY, ESPECIALLY WITH ALL THOSE PESKY AFTERSHOCKS.

YOU REMEMBER WHAT THOSE ARE, RIGHT?

>> I REMEMBER.

THEY'RE LITTLE QUAKES AFTER A BIGGER EARTHQUAKE.

>> LET'S HOPE THEY'RE OVER.

I THINK I'LL GO BACK TO WORK.

THERE ARE SO MANY MOMS TO MAKE FOOD FOR TODAY.

>> MRS. PTERANODON, OH, I JUST HOPE MY LITTLE ONES GROW UP TO BE AS NICE AND CALM AND WELL-BEHAVED AS YOUR CHILDREN.

>> AWK.

WHY, THANK YOU, AND YOUR KIDS WILL BE GREAT.

I'M SURE OF IT.

>> REALLY?

UH, HOW CAN YOU BE SURE?

>> WELL-- >> HOW DO YOU KNOW YOUR EGGS ARE GONNA HATCH RIGHT?

I'VE NEVER HAD AN EGG BEFORE.

I'M SO NERVOUS.

WERE YOU NERVOUS?

>> YEAH.

>> I GUESS I HAVE SO MANY QUESTIONS.

>> HEH HEH.

YES.

>> DO YOU THINK WE CAN GET A CLOSER LOOK AT THE EGGS, MRS.

CONDUCTOR?

>> OH, UH, WHAT DO YOU THINK, MOMS?

CAN THE KIDS COME CLOSER?

>> WELL, OF COURSE.

COME CLOSER, KIDS.

>> OH!

BUT NOT TOO CLOSE!

>> I WONDER WHICH EGG GOES WITH WHICH MOM.

>> LET'S SEE IF WE CAN REMEMBER.

>> UH, UH, I'M SURE SONNY BOY WOULD KNOW, BUT I SURE DON'T.

>> LET'S FIGURE IT OUT OURSELVES!

>> HMM.

THESE EGGS KIND OF LOOK ALIKE.

>> WELL, LET'S SEE.

I THINK THE LITTLE EGGS MIGHT BELONG TO MRS. TRICERATOPS AND THE SORT OF YELLOW ONES MIGHT BE MRS. TROODON'S, BUT I'M NOT REALLY SURE.

>> SINCE TRICERATOPS IS SUCH A BIG DINOSAUR, I BET THE BIGGER EGG IS THE TRICERATOPS AND THE SMALL ONES ARE--OHH!

[RUMBLING] OOH!

ARE THEY HATCHING?

>> BLLLAUGH!

NOPE.

IT'S JUST ANOTHER AFTERSHOCK.

NOTHING TO WORRY ABOUT KIDS.

IT'LL BE OVER SOON.

>> AW.

>> [GASP] OH, THEY'RE FINE.

THEY'RE ALL FINE.

>> WHOO-HOO!

I LOVE AFTERSHOCKS!

>> [WHIMPERS] MAKE IT STOP.

>> NOTHING TO WORRY ABOUT, FOLKS.

ANOTHER AFTERSHOCK.

>> I'D PREFER IT IF THE SHAKING STOPPED.

[SIGH] >> TOLD YOU.

NOTHING TO WORRY ABOUT.

>> WELL, EXCEPT MY EGGS.

>> LET'S GO CHECK ON OUR FAMILY, KIDS.

>> ARE THE EGGS ALL RIGHT?

>> UH-HUH.

>> JUST FINE.

>> THERE.

NOTHING TO WORRY ABOUT, LIKE I SAID.

>> I WONDER HOW THOSE EGGS FELT ABOUT THE AFTERSHOCK.

DO YOU THINK THEY LIKED IT AS MUCH AS I DID?

WHAT DO YOU THINK THE LITTLE DINOSAURS IN THE EGGS ARE DOING?

DO YOU THINK THEY'RE ASLEEP?

>> BUT HOW DO THE BABIES BREATHE IN THERE?

>> I HAVE A HYPOTHESIS.

THE EGG SHELLS MUST BE THIN ENOUGH FOR THE BABIES INSIDE TO BREATHE.

>> BUT THEY STILL MUST BE REALLY STRONG BECAUSE NONE OF THEM CRACKED DURING THE AFTERSHOCK.

>> WELL, YOU'RE BOTH RIGHT.

THE EGGSHELLS ARE THIN ENOUGH FOR THE BABIES INSIDE TO BREATHE, BUT THEY'RE ALSO REALLY STRONG.

IF YOU LOOK CLOSELY, YOU CAN SEE LOTS OF TINY HOLES IN THE SHELLS.

TAKE A GANDER THROUGH MY SUPERMAGNIFYING GLASS.

THOSE TEENY HOLES ARE CALLED PORES.

>> I DON'T REMEMBER BEING IN AN EGG, BUT I LIKE BREATHING.

[BREATHES DEEPLY] HELLO?

YOU GUYS BREATHING IN THERE?

[RUMBLING] >> OHH!

IS IT ANOTHER AFTERSHOCK?

>> NO, SHINY.

IT'S THE EGGS!

>> AWK!

BUDDY'S RIGHT.

>> THEY'RE HATCHING!

>> [INDISTINCT CHATTER] >> OH, IS IT MINE?

[CRACKING] >> WHOA!

THERE GOES ANOTHER ONE!

>> THE EGGS ARE CRACKING RIGHT ON TIME.

>> NOW ALL OF THE EGGS ARE CRACKING.

THIS IS AMAZING.

>> I'M SO NERVOUS, SO EXCITED, SO--AHH.

>> HEH.

BEEN THERE, PAL, BEEN THERE.

>> OH, WOW!

>> OHH!

WHO'S MY BABY?

HEY!

>> AWW.

>> PSST.

SHINY AND DON, DON'T FORGET ABOUT OUR LITTLE MOM SURPRISE IN THE PASSENGER COACH.

>> OH, RIGHT, DAD.

ON IT.

>> HEE HEE HEE.

>> HA HA HA!

>> YES.

>> WHERE'D YOU GET THE MUD, DAD?

>> FROM THE BIG POND?

THEY ALWAYS HAVE THE BEST MUD THERE.

ALL RIGHT, DON.

YOU GO FIRST.

>> OOH!

THIS IS FUN!

I LOVE MUD!

>> AND MOM'S GONNA LOVE IT!

>> LOOK AT THOSE TEENY FEATHERS.

>> YOU KNOW, TINY.

IT WOULD BE FUN TO COMPARE THE BABIES' FEATURES TO THEIR PARENTS'.

>> YEAH.

LET'S DO IT!

>> COMPARE AND CONTRAST, KIDS!

HAVE FUN!

REMEMBER, DINOSAUR NEWBORNS OFTEN LOOK DIFFERENT FROM THEIR PARENTS WITH BIGGER EYES AND ROUNDER FACES.

>> HMM.

LOOK AT THE TRICERATOPS BABY.

THE LITTLE GUY LOOKS LIKE HE'LL SPROUT 3 HORNS JUST LIKE HIS MOM AND DAD.

>> BUT HE DOESN'T HAVE HORNS YET, JUST LITTLE NUBS.

HI, BABY TROODON.

YOU LOOK JUST LIKE YOUR MOM AND DAD.

YOU EVEN HAVE A TEENY, TINY TOE CLAW.

>> LOOK AT THE MAIASAURA BABY'S LITTLE FINGERS.

I EVEN SEE LITTLE MAIASAURA TEETH.

>> LOOK AT THE BABY VELOCIRAPTOR AND HIS FEATHERS.

ONE DAY HE'LL HAVE FEATHERS LIKE HIS MOM.

>> OH, YES!

THE OLDER BABIES GET, THE MORE THEY LOOK LIKE THEIR SPECIES.

>> BUT ALL OF THEM START FROM LITTLE EGGS.

>> CORRECT, BUDDY.

EVEN THE BIGGEST DINOSAURS LIKE ARGENTINOSAURUS HATCH OUT OF AN EGG THAT'S ONLY ABOUT THIS BIG.

>> WHOA!

REALLY?

>> HELLO.

IT'S FAMILY PORTRAIT TIME.

WHO WANTS ME TO DRAW THEIR BABY PICTURE?

>> OH, WE DO!

>> US FIRST!

>> WE TOTALLY DO!

[CRYING] [OTHER BABIES CRYING] >> UM, MOM.

MAYBE IT'S TIME TO GET BACK TO DAD, SHINY, AND DON.

>> GOOD IDEA.

CONGRATULATIONS, EVERYBODY.

>> SURPRISE!

>> IT'S A SPECIAL "WE LOVE YOU, MOM" PRESENT.

>> YEAH, BECAUSE WE DO.

>> AWK!

OH, HOW LOVELY.

>> YEP.

IT'S OUR FOOTPRINTS, SO YOU CAN REMEMBER US WHEN WERE THIS BIG!

>> BECAUSE ONE DAY, WE'LL BE OLDER AND BIGGER, AND I'LL BE A GIANT T. REX.

RAWWR!

>> THANK YOU, KIDS.

IT DOESN'T MATTER HOW BIG YOU ARE, YOU'LL ALWAYS BE MY LITTLE BABIES.

>> GROUP HUG!

>> [GIGGLING] WE LOVE YOU, MOM!

[WHISTLE BLOWS] >> HI, THERE.

I'M DR. SCOTT, THE PALEONTOLOGIST, AND DO YOU KNOW WHAT I'M HOLDING?

THESE ARE PIECES OF ACTUAL DINOSAUR EGGSHELL FROM A REAL DINOSAUR EGG.

DID YOU KNOW THAT ALL DINOSAURS HATCHED FROM EGGS?

IT'S TRUE.

EVEN HUGE DINOSAURS LIKE BRACHIOSAURUS CAME FROM AN EGG NOT MUCH BIGGER THAN THIS ONE.

WE DON'T KNOW WHAT KIND OF DINOSAUR THESE EGGSHELLS CAME FROM, BUT ONE THING WE DO KNOW IS THAT THESE FOSSILS ARE ABOUT 75 MILLION YEARS OLD.

LIKE BIRDS, DINOSAURS LAID THEIR EGGS IN CIRCULAR NESTS, USUALLY WITH ABOUT 20-25 EGGS IN EACH NEST.

ALSO LIKE BIRDS, DINOSAURS OFTEN NESTED IN GROUPS OR COLONIES.

NESTING IN COLONIES ALLOWED THE ADULTS TO PROTECT THEIR EGGS AND BABIES FROM PREDATORS, WHICH WAS VERY IMPORTANT TO THOSE BABY DINOSAURS.

OK. 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!
