One day, the brontosaurus named Sethi-Mas was walking through the forest, searching for leaves. He had a short neck and long legs. He came upon a triceratops smashing his head against a coconut tree.
“What is wrong?” Sethi-Mas asked the stranger.
The triceratops stopped what he was doing, and turned around. “I have something stuck in my throat, and a friendly troodon told me this would help.”
“Let me help you instead,” the brontosaurus said. He stuck his head inside the triceratops’s mouth and used his teeth to remove what was a small twig in the other dinosaur’s mouth.
Suddenly, the ground began to shake, and Sethi-Mas lost his footing. He fell to the ground, and his head smacked into a rock.
“Come on!” the triceratops yelled at the unconscious Sethi-Mas. “We need to get away!” When he was not answered, the horned dinosaur picked up the brontosaurus by his short neck and began to drag him to safety.
His neck got stretched out, and soon it became the famous long neck we know today-as it is found in all sauropods.
