Why dinosaurs are big and got ecstinced
by: Hester S., Grade: 3


About 1000 million years ago
dinosaurs romed the land but when the first dinosaurs came
they were tiny and never grew untill a dinosaur had
an idea if two dinosaurs stood at two ends and held on to another slowly walking
backwards it would strech and get very tall. soon every
dinosaur had become tall but sill not big so a parasourolophus said to eat more and get fatter and become bigger but if there are no more of us and the plants tuff. a few years later the parasourolophus was
right all of the dinosaurs and plant had gone.
