ON THE DINOSAUR TRAIN, BUDDY AND THE PTERANODON PALEONTOLOGIST.

ON THE DINOSAUR TRAIN, BUDDY AND THE PTERANODON KIDS PLACED ALL THE DINOSAURS TRAIN, BUDDY AND THE PTERANODON KIDS PLACED ALL THE DINOSAURS INTO GROUPS BASED ON THEIR KIDS PLACED ALL THE DINOSAURS INTO GROUPS BASED ON THEIR FEATURES.

TODAY PALEONTOLOGISTS INTO GROUPS BASED ON THEIR FEATURES.

TODAY PALEONTOLOGISTS DO THE VERY SAME THING.

WE CALL FEATURES.

TODAY PALEONTOLOGISTS DO THE VERY SAME THING.

WE CALL IT CLASSIFICATION.

STEGOSAURUS DO THE VERY SAME THING.

WE CALL IT CLASSIFICATION.

STEGOSAURUS AND KENTROSAURUS ARE PART OF A IT CLASSIFICATION.

STEGOSAURUS AND KENTROSAURUS ARE PART OF A DINOSAUR GROUP CALLED AND KENTROSAURUS ARE PART OF A DINOSAUR GROUP CALLED STEGOSAURS THAT ALL HAVE PLATES DINOSAUR GROUP CALLED STEGOSAURS THAT ALL HAVE PLATES AND SPIKES RUNNING DOWN THE STEGOSAURS THAT ALL HAVE PLATES AND SPIKES RUNNING DOWN THE MIDDLE OF THEIR BACKS.

THE AND SPIKES RUNNING DOWN THE MIDDLE OF THEIR BACKS.

THE STEGOSAUR FAMILY IS CLOSELY MIDDLE OF THEIR BACKS.

THE STEGOSAUR FAMILY IS CLOSELY RELATED TO ANKYLOSAURS LIKE STEGOSAUR FAMILY IS CLOSELY RELATED TO ANKYLOSAURS LIKE ANKYLOSAURUS AND RELATED TO ANKYLOSAURS LIKE ANKYLOSAURUS AND EUOPLOCEPHALUS, WHICH ALL HAVE ANKYLOSAURUS AND EUOPLOCEPHALUS, WHICH ALL HAVE BONEY ARMOR COVERING THEIR EUOPLOCEPHALUS, WHICH ALL HAVE BONEY ARMOR COVERING THEIR BODIES.

TODAY STEGOSAURS AND BONEY ARMOR COVERING THEIR BODIES.

TODAY STEGOSAURS AND ANKYLOSAURS FORM AN EVEN BIGGER BODIES.

TODAY STEGOSAURS AND ANKYLOSAURS FORM AN EVEN BIGGER GROUP CALLED ARMORED DINOSAURS.

ANKYLOSAURS FORM AN EVEN BIGGER GROUP CALLED ARMORED DINOSAURS.

WE CAN DO THE SAME THING WITH GROUP CALLED ARMORED DINOSAURS.

WE CAN DO THE SAME THING WITH MEAT-EATING DINOSAURS, OR WE CAN DO THE SAME THING WITH MEAT-EATING DINOSAURS, OR THEROPODS.

RAPTORS LIKE MEAT-EATING DINOSAURS, OR THEROPODS.

RAPTORS LIKE VELOCIRAPTOR HAD FEATHERS ON THEROPODS.

RAPTORS LIKE VELOCIRAPTOR HAD FEATHERS ON THEIR BODIES AND A BIG CLAW ON VELOCIRAPTOR HAD FEATHERS ON THEIR BODIES AND A BIG CLAW ON THE SECOND TOE, AND RAPTORS ARE THEIR BODIES AND A BIG CLAW ON THE SECOND TOE, AND RAPTORS ARE CLOSELY RELATED TO HUGE THE SECOND TOE, AND RAPTORS ARE CLOSELY RELATED TO HUGE TYRANNOSAUR DINOSAURS LIKE CLOSELY RELATED TO HUGE TYRANNOSAUR DINOSAURS LIKE T. REX.

SCIENTISTS WHO STUDY TYRANNOSAUR DINOSAURS LIKE T. REX.

SCIENTISTS WHO STUDY ANIMALS LIVING TODAY ALSO USE T. REX.

SCIENTISTS WHO STUDY ANIMALS LIVING TODAY ALSO USE CLASSIFICATION, DIVIDING UP ANIMALS LIVING TODAY ALSO USE CLASSIFICATION, DIVIDING UP CREATURES ACCORDING TO THEIR CLASSIFICATION, DIVIDING UP CREATURES ACCORDING TO THEIR FEATURES.

FOR EXAMPLE, MAMMALS CREATURES ACCORDING TO THEIR FEATURES.

FOR EXAMPLE, MAMMALS LIKE RABBITS, HORSES, AND FEATURES.

FOR EXAMPLE, MAMMALS LIKE RABBITS, HORSES, AND CHIPMUNKS ALL HAVE HAIR, AND LIKE RABBITS, HORSES, AND CHIPMUNKS ALL HAVE HAIR, AND BIRDS LIKE CHICKENS, BLUE JAYS, CHIPMUNKS ALL HAVE HAIR, AND BIRDS LIKE CHICKENS, BLUE JAYS, AND FLAMINGOES ARE A WHOLE BIRDS LIKE CHICKENS, BLUE JAYS, AND FLAMINGOES ARE A WHOLE DIFFERENT GROUP.

THEY ALL HAVE AND FLAMINGOES ARE A WHOLE DIFFERENT GROUP.

THEY ALL HAVE FEATHERS.

OK. KEEP WATCHING FOR DIFFERENT GROUP.

THEY ALL HAVE FEATHERS.

OK. KEEP WATCHING FOR MORE DINOSAUR DISCOVERIES.

FEATHERS.

OK. KEEP WATCHING FOR MORE DINOSAUR DISCOVERIES.
