Dinosaur Train | Footprints and Trackways

>> A TRACKWAY!

♪ DUN DUN DUN ♪ >> HMM.

1, 2, 3 TOES.

THIS CREATURE HAS 3-TOED FEET.

>> WHAT'S IT MEAN, BUDDY?

>> I THINK IT ADDS UP TO THIS--WE'RE TRACKING A THEROPOD!

>> A THEROPOD?

YOU MEAN-- >> YEP.

ONE, BIG LEGS WITH 3-TOED FEET.

TWO, LOTS OF TEETH FOR EATING MEAT.

3, A LONG TAIL FOR BALANCING WELL, AND 4, THEROPODS HAVE A GREAT SENSE OF SMELL.

>> WHOA!

YOU KNOW ALL THAT FROM LOOKING AT ITS FOOTPRINTS?

>> NO.

IT WAS JUST A GUESS, BUT LET'S KEEP FOLLOWING HIM, AND MAYBE WE CAN FIND OUT.

>> [SQUAWK] HEY!

DON'T SNEAK UP ON ME LIKE THAT.

>> WE'RE SORRY.

WE WERE TRACKING YOU.

>> JUST FOR FUN.

WE'RE PLAYING DETECTIVES!

>> TRACKING ME?

OH, WONDERFUL.

WHAT DID YOU DISCOVER?

>> WE WERE TRYING TO FIGURE OUT WHAT SPECIES YOU ARE.

>> I'M CALLED AN ENANTIORNITHINE.

>> ENANTIORNITHINE!

>> BUT ARE YOU ALSO A THEROPOD?

>> [SQUAWK] I SURE AM!

>> COOL!

BECAUSE I'M A THEROPOD, TOO!

>> HEY!

LET'S COMPARE FEATURES.

I SEE WE HAVE 3-TOED FEET.

>> AND YOU BOTH HAVE LONG TAILS.

DO YOU HAVE A GREAT SENSE OF SMELL?

>> HA!

I LIKE TO THINK SO.

HA HA HA!

I SMELL BERRIES AND BUGS!

I BETTER GET BACK TO HUNTING FOR THEM.

BYE!

>> BYE!

>> ANOTHER BUG-LOVER!

TRACKING IS FUN!

>> IT IS.

LET'S FIND SOME MORE!

>> FOLLOW YOUR T. REX NOSE, BUDDY!

>> WHOA!

LOOK AT THESE, DON.

>> BIG, BIG TRACKS.

>> THEY SMELL KIND OF FAMILIAR.

1, 2, 3, 4, TOES.

I THINK IT'S SOME KIND OF QUADRUPED.

>> YOU MEAN, IT WALKS ON 4 LEGS?

>> YEP!

SEE, THESE ARE ITS BACK FEET, AND THESE LOOK LIKE ITS FRONT FEET, AND LOOK AT THIS TRACKWAY.

IT'S LIKE THE CONDUCTOR SAID.

THE PRINTS ARE FAR APART.

YOU CAN TELL THIS DINOSAUR IS BIG!

>> MAYBE WE SHOULD TRACK SOMETHING LITTLE, BUDDY.

WHAT IF IT WANTS TO EAT US?

>> AW, I BET IT'S A QUADRUPED, DON.

THEY'RE HERBIVORES.

YOU KNOW, HERBIVORES EAT PLANTS, NOT T. REXES.

>> WHAT ABOUT PTERANODONS?

>> NAH.

THEY WON'T EITHER OF US.

>> OK, BUDDY.

YOU'RE USUALLY RIGHT ABOUT THESE THINGS.

UH-OH.

THOSE ARE A WHOLE LOT OF TRACKS.

>> YEP!

WHATEVER THIS DINOSAUR IS, I THINK WE FOUND A WHOLE HERD OF THEM, YOU KNOW, A BUNCH OF DINOSAURS ALL TRAVELING TOGETHER.

>> I THOUGHT YOU WERE GONNA SAY THAT.

>> THEY GO THIS WAY!

COME ON!

>> UM, LET ME CHECK WITH DAD!

[SQUAWK] HEY, DAD!

>> HI, DON!

EVERYTHING ALL RIGHT?

>> YEAH.

WE FOUND A LOT OF TRACKS.

>> WELL, THAT'S GREAT, SON >> HI.

I'M DR. SCOTT THE PALEONTOLOGIST, AND THESE ARE T. REX FOOTPRINTS.

PALEONTOLOGISTS HAVE DISCOVERED THOUSANDS OF DINOSAUR FOOTPRINT FOSSILS.

THEY'VE BEEN FOUND ON EVERY CONTINENT.

>> DINOSAUR FOOTPRINTS.

>> SOMETIMES, WE JUST FIND ONE FOOTPRINT, AND SOMETIMES, WE FIND A LONG SERIES OF FOOTPRINTS CALLED TRACKWAYS.

FOSSIL TRACKWAYS TELL US HOW DINOSAURS MOVE.

TRACKS TELL US THAT DINOSAURS STOOD UPRIGHT WITH THEIR FEET CLOSE TOGETHER, AND SINCE WE DON'T FIND MANY SIGNS OF DRAGGING TAILS, WE KNOW THAT DINOSAURS HELD THEIR TAILS IN THE AIR.

>> THAT'S COOL.

>> PALEONTOLOGISTS HAVE ALSO FOUND TRACKWAYS OF SPRAWLING CROCODILES AND SLITHERING SNAKES AND HOPPING FROGS.

OF COURSE, ANIMALS LIVING TODAY MAKE TRACKS, TOO.

YOU'VE PROBABLY SEEN SOME RIGHT AROUND YOUR OWN HOME.

HEY.

I'VE GOT AN IDEA.

GET OUTSIDE, GET INTO NATURE, AND MAKE YOUR OWN
