- HI THERE.

I'M DR. SCOTT THE PALEONTOLOGIST.

THIS IS A MAP OF THE EARTH, OUR PLANET.

EARTH HAS SEVEN CONTINENTS: NORTH AMERICA, SOUTH AMERICA, EUROPE, AFRICA, ASIA, AUSTRALIA, AND ANTARCTICA.

MILLIONS OF YEARS AGO, ALL OF THESE CONTINENTS WERE JOINED IN ONE GIGANTIC SUPERCONTINENT THAT WE CALL PANGAEA.

WHEN DINOSAURS FIRST APPEARED ON EARTH IN THE TRIASSIC PERIOD, OVER 200,000,000 YEARS AGO, THEY ALL LIVED ON PANGAEA.

BUT THE SURFACE OF THE EARTH IS ALWAYS CHANGING AND MOVING.

THE EARTH'S OUTER CRUST IS MADE UP OF LARGE CHUNKS CALLED PLATES.

DEEP BELOW THE CRUST, HOT MOLTEN ROCKS PUSHED TO THE SURFACE AND MOVED THE PLATES AROUND.

THAT CAUSES THE CONTINENTS TO MOVE AS WELL, SOMETIMES BREAKING APART AND OTHER TIMES BUMPING INTO EACH OTHER.

IT TOOK MILLIONS OF YEARS, BUT EVENTUALLY PANGAEA BROKE UP INTO SMALLER CHUNKS OF LAND FORMING THE CONTINENTS WE KNOW TODAY.

AS PANGAEA BROKE APART, THE GROUPS OF DINOSAURS ONBOARD EACH OF THE CONTINENTAL RAFTS WENT THEIR SEPARATE WAYS.

SO ALTHOUGH WE FIND MEAT-EATING THEROPOD DINOSAURS ON EVERY CONTINENT, THEY INCLUDE MANY DIFFERENT KINDS, LIKE T. REX IN NORTH AMERICA AND CRYOLOPHOSAURUS IN ANTARCTICA.

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