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

THERE WERE GIANT, MEAT-EATING IN ALL SHAPES AND SIZES.

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

THERE WERE BIGGER PLANT-EATING SAUROPODS LIKE APATOSAURUS.

THERE WERE LITTLE DINOSAURS, SUCH AS TINY LIKE APATOSAURUS.

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

SOME FEATHERED MICRORAPTOR, AND BIRDS LIKE ARCHAEOPTERYX.

SOME DINOSAURS, LIKE CORYTHOSAURUS LIKE ARCHAEOPTERYX.

SOME DINOSAURS, LIKE CORYTHOSAURUS AND CRYOLOPHOSAURUS, HAD CRESTS.

SCIENTISTS TRICERATOPS AND EINIOSAURUS, HAD HORNS AND FRILLS.

SCIENTISTS HAVE A WORD FOR SUCH A WIDE HORNS AND FRILLS.

SCIENTISTS HAVE A WORD FOR SUCH A WIDE VARIETY.

WE CALL IT DIVERSITY.

THE PTERANODON KIDS ARE HELPING VARIETY.

WE CALL IT DIVERSITY.

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

TO GATHER A GREAT DIVERSITY OF DINOSAURS--26 DIFFERENT KINDS.

NOW, 26 SOUNDS LIKE A LOT, BUT DINOSAURS--26 DIFFERENT KINDS.

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

ONE DINOSAUR SPECIES ALMOST 1,000 DIFFERENT KINDS OF DINOSAURS.

ONE DINOSAUR SPECIES THE PTERANODON FAMILY JUST MET DINOSAURS.

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

WE THINK IT WAS A FAST NECK AND A LONG TAIL AND LONG LEGS.

WE THINK IT WAS A FAST RUNNER, A LOT LIKE THIS LEGS.

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

RUNNER, A LOT LIKE THIS MODERN-DAY ANIMAL, THE OSTRICH.

EVERY YEAR, PALEONTOLOGISTS LIKE MODERN-DAY ANIMAL, THE OSTRICH.

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

MAYBE YOU'LL GROW UP MORE OUT THERE WAITING TO BE DISCOVERED.

MAYBE YOU'LL GROW UP TO BE A PALEONTOLOGIST AND DISCOVERED.

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

OK, KEEP WATCHING FOR DISCOVER SOME AMAZING NEW CREATURES.

OK, KEEP WATCHING FOR MORE DINOSAUR DISCOVERIES.
